FOREWORD (Not a part of ANSI/BHMA A156.18)

The general classification of builders hardware includes a wide variety of items which are divided into

several categories. To recognize this diversity, a sectional classification system has been established. Each

Standard is the result of the collective efforts of members of the Builders Hardware Manufacturers

Association, Inc. who manufacture the products included in each Section. The total product standards effort

is, therefore, a collection of Section Standards, each covering a specific category of items.

In BHMA Standards, performance tests and, where it has been necessary, material and dimensional

requirements have been established to ensure safety, security, and stability to which the public is entitled.

There are no restrictions on design except for those dimensional requirements imposed for the reasons given

above. It is also required that some hardware items fit certain specified cutout dimensions.

This Standard on materials and finishes contains a description of types of finishes and divides them into

categories. A numbering system has been established which identifies base material and finish.

Performance test methods for finishes are included. Requirements and exemptions concerning appearance

are contained in this Standard.

The BHMA recognizes that new finishes, methods and materials will be developed. With this in mind, the

Association plans to update, correct and revise this Standard on a regular basis.

Only finishes produced by three or more manufacturers are listed and are numbered starting with 600.

Numbers 001 through 599 are reserved for individual manufacturers to use, as they desire for their own

unique finishes.

The finish test methods, code numbers and finish descriptions contained in this Standard are intended to

apply to the builders hardware industry. However, the Standard is suitable for use in other industries.

1. SCOPE

1.1 This Standard establishes finish test methods and code numbers for finishes on various base materials.

It includes criteria for viewing comparative finishes to the BHMA match plates and establishes five

categories of finishes.

2. DEFINITIONS

2.1 Blackened A surface treated to be light absorbing, and darkened.

2.2 Bright A reflective mirror like surface.

2.3 Coating Coating is the application, of organic or inorganic materials to, or the conversion of the

surface of the base material or substrate, for the changing of appearance, or for protection or both. The

topcoat when applied establishes the type of coating for test purposes. When the top coat is transparent, it is

often referred to as a clear coat.

2.3.1 Organic Coating Coatings with a material containing carbon compounds, excepting cyanides and

carbonates, and including mixtures of organic and inorganic materials.

2.3.2 Inorganic Coating Coating with metallic or other non-carbonaceous materials or conversion of

the surface to an oxide.

2.3.2.1 Plating Coating with a metallic deposit by chemical, electro-chemical, mechanical or

electro-mechanical means.

2.3.2.2 Oxidizing Coating by conversion of the surface of the base material to an oxide by addition

of oxygen or removal of hydrogen.

2.3.2.2.1 Anodizing (aluminum) Coating by electro-chemical process which converts the surface

(aluminum) metal to (aluminum) oxide due to reactions at the anode in an acidic solution.

2.3.3 Vacuum Applied Coating Electrochemical or electrophysical (PVD or physical vapor deposition)

deposition, operated in a vacuum to deposit an adherent, dense, thin film coating.

2.4 Corrosion The result of breakdown or eating away of the base material or substrate, not to be

confused with staining. Corrosion of brass or bronze material can be green, brown or pink; corrosion of steel

or stainless steel material is red rust, corrosion of aluminum or zinc base material is white.

2.6 Finish Matching Equivalent in color, texture, and appearance.

2.7 Relieved To set off by contrast through the partial removal of finish, creating a brushed, satin, or

antique effect.

2.8 Satin A smooth dull finish with or without a directional pattern.

2.9 Significant Surfaces Surfaces of a product that are visible or exposed after the product are installed.

2.10 Stain Any obvious color change other than corrosion, which cannot be removed by rinsing with water.

2.11 Substrate The surface to which a coating is applied; may be a coating or the base material.

2.12 Unstable Finish A finish that intentionally lacks sufficient protection to ensure consistent color,

texture, and appearance for the intended period of use.

5

3. FINISH TEST METHODS AND CRITERIA

3.1 These test methods do not predict the performance life of the finishes in actual use but are used as a

quality control method to ensure consistent finish quality. Consult the applicable BHMA Product Standards

for minimum exposure times and other values.

3.1.1 Exempt Surfaces Surfaces on which a controlled deposit ordinarily cannot be obtained, such as

holes, edges, recesses, bases of angles, and similar areas, are exempt from the requirements for significant

surfaces.

3.1.2 Exempt Finishes Category B and equivalent finishes 634, 640, 683, 703, 704, 727 are not subject to

testing but may be listed in the certified products directory to represent the manufacturer’s product line.

3.1.3 Test Specimens Actual product components shall be used except where otherwise specified.

Components without surfaces which are compatible with the prescribed test methods, shall use a finished flat

test panel using substrate of the same base material of the actual product or component. The flat panels shall

have a minimum exposed area of 2.50 x 3.75 in (64 x 95 mm) and shall be 0.020 to .25 in (0.5 to 6.4 mm) thick.

A painted finish in several different colors, where each color is composed of all the same materials except

for variations in tints, is considered to be one finish type for test purposes.

3.2 Salt Spray Test This test shall be conducted in accordance with ASTM B 117-03 Standard Method of

Salt Spray (Fog) Testing. Parts shall withstand exposure for the time specified in the applicable

ANSI/BHMA A156 Series Standard without base material or substrate corrosion exceeding one spot visible

to the unaided eye per one square inch (25.4 square mm) of significant surface and without any spot larger

than 1/16 in (1.6 mm) in diameter. The spread of corrosion on significant surfaces that originate from holes,

edges, recesses, and bases of angles, shall not exceed 1/16 in. (1.6mm). Staining shall not exceed 5% of the

significant surface area of the component under test and without any spot larger than 1/4 in. (6.4 mm) in

diameter.

3.3 Humidity Test This test shall be conducted in a chamber with conditions as described in ASTM

D1735-04, except that this test shall be conducted in a chamber having a 95% ± 5% relative humidity. The

parts shall be allowed to stabilize at room temperature for 30 minutes before they are examined. Blistering

or staining of the part shall not be visible to the unaided eye. The coating shall, within an additional 15

minutes, pass a pencil hardness test (see 3.4) as specified in the applicable ANSI/BHMA A156 Series

Standard and shall pass the method B Cross-Cut Tape Test as defined in ASTM D 3359-02 Method for

Measuring Adhesion by Tape Test.

3.4 Pencil Hardness Test.

3.4.1. Berol Turquoise pencil lead of the hardness specified in the applicable ANSI/BHMA A156 Series

Standard, if applicable, shall be placed in a Hardness Test Fixture similar to the one shown in Figure 1 with

1/8 to 1/4 in (3.2 to 6.4 mm) of lead exposed beyond the tip of the holder. The test part shall be grounded to

the test fixture chassis. Abrade, in accordance with 3.4.2, the end of the lead flat and perpendicular to its

axis with the means provided in the Hardness Test Fixture. Using a 3 lb. 10 oz ± 1 oz (1644 g ± 28.3 g)

weight bearing on the pencil lead and as provided in the Fixture, push the coated surface under test toward

and beneath the lead for ¼ to ½ in. (6.4 to 12.7 mm). Failure occurs if the coating is removed to the

substrate, or near enough to the substrate, to activate the holiday detector alarm on the fixture.

3.4.2 Abrade the lead with #400 grit sandpaper and finish with light pressure to minimize grooves in the

abraded surface. The circular edge shall be sharp, not serrate, when inspected with 5X magnification after

each abrading. Repeat the abrading as required until the inspected edge is sharp. By rotating the lead holder

after each test either 180 or 120 degrees ± 1 degree, three tests maximum shall be performed per abrading

3.4.3 In lieu of the BHMA Hardness Test Fixture a similar fixture is permitted to be used. The following

details are required.

6

a) lead holder firmly held at 45 degrees ± 1 degree to test surface

b) Weight and lead holder “float” vertically on a miniature slide

c) Table moves on linear ball bearings

d) Lead abrading means is provided for 90

0

dressing

e) The BHMA Holiday Detector alarm circuit of Figure 2

3.5 Perspiration Test This test shall be conducted using a reagent made up by weight of 5% sodium

chloride, 5% acetic acid, 3% butyric acid, 3% valeric acid and 84% distilled water which is less than one

year old and has been stored at 40 degree F ± 5 degrees F (4 degrees C ± 3 degrees C). A dam of epoxy or

similar adhered material, shall be used to contain the solution over an area between ½ and 1 square in. (323

and 645 square mm) with a minimum solution depth of 1/16 in. (1.6 mm). Apply the reagent; let stand for

15 minutes and wash off with cold water. The coating shall then pass a pencil hardness test in accordance

with 3.4 using a pencil lead of 2B hardness. This constitutes one cycle. Repeat within the test area

(avoiding the same line), the number of cycles specified in the applicable ANSI/BHMA A156 Series

Standard.

3.6 Ultraviolet Light and Condensation Test This test shall be conducted in accordance with ASTM

G154-05 Standard Practice for Operating Fluorescent Light Apparatus for UV Exposure of Nonmetallic

Materials except as follows. For all products, use UVA-340 lamps with a typical irradiance: 0.77 W/m

2

/nm.

The test cycles and duration shall be specified in the applicable ANSI/BHMA A156 Series Standards. Three test

specimens shall be tested for each finish and one additional specimen shall be retained for comparison at the end

of the test. For coatings used on multiple base materials, testing of only one material is required. The retained

specimen shall be stored in a controlled environment and protected from UV exposure. Start the test at the

beginning of a UV cycle and end it at the conclusion of a condensation cycle. Test specimens shall be the actual

product or component. Refer to 3.1.2 when finished product or component cannot be adopted to the UV test

equipment. The test specimen shall be mounted as specified in ASTM G 154. Any of the cut edges of the panels

are permitted to be sealed with silicone sealant or vinyl electrical tape. At the conclusion of the test, the retained

panel and the tested panels shall be viewed in accordance with 4.3.3 and shall appear the same. Visual failure

modes shall be any chipping, flaking, cracking, color loss, or change (from clear to white, yellow or brownish).

At the completion of the Ultra Violet Light and Condensation Test, the panel shall pass F pencil hardness when

tested in accordance with 3.4.

3.7 Taber Abrasion Test This Test shall be conducted in accordance with ASTM D4060-01 Test Method

for Abrasion Resistance of Organic Coatings by the Taber Abraser. A uniform thickness of the coating to be

tested shall be applied to a .060 in. (1.5 mm) minimum thick coupon using the manufacturer's normal coating

materials and processes. The coating thickness of specimen shall reflect the average coating thickness of the

manufacturer's products. The wheel shall be a CS-10 calabrase with a 1000 gram load. Reface the wheel

every 500 cycles. Failure constitutes wearing through the coating to the coupon prior to completing the

number of cycles specified in the applicable ANSI/BHMA A156 Series Standard. Detection shall be by a

BHMA Holiday Detector (see Figure 2) or by visual inspection when the conductivity test is not applicable

with non-conducting substrates nor with conductive coatings.

3.8 CASS Salt Spray Test. This test shall be conducted in accordance with ASTM B368—97

(2003)Standard Method for Copper-Accelerated Acetic Acid-Salt Spray (for) Testing. Parts shall withstand

exposure for the time specified in the applicable ANSI/BHMA A156 Series Standard without base material

or substrate corrosion exceeding one spot visible to the unaided eye per one square inch (645 square mm) of

significant surface and without any spot larger than 1/16

in. (1.6 mm) in diameter. The spread of corrosion

on significant surfaces that originate from holes, edges, recesses, and bases of angles, shall not exceed 1/16

in. (1.6mm). Staining shall not exceed 5% of the significant surface area of the component under test and

without any spot larger than 1/4 in. (6.4 mm) in diameter.

4. MATERIALS, CATEGORIES, AND FINISHES

4.1 Materials Except for the generic classifications of materials shown, there shall be no restrictions other

than those specified in the applicable ANSI/BHMA A156 Series Standard and so long as good commercial

practices are observed. The following identification numerals are used and often appear as the first numeral

in the product type numbers used in individual ANSI/BHMA A156 Series Standards and identify the

predominant material from which the product is made:

4.2 Categories BHMA code numbers for finishes fall into one of five categories defined as follows:

A. Category A finishes are those that shall match BHMA match plates and are applied to the base

material or are the base material defined by the description in 5.2 when viewed according to the formula in

4.3.3. Nominal reference values for color measuring equipment using the L*a*b* scale are listed in the

appendix.

B. Category B finishes are those that are unstable and are applied to the base material or are the base

material defined by the description in 5.2. These finishes shall be compatible with the BHMA match plates,

but these finishes cannot and do not match from one alloy or form of material to the next and from one

manufacturer to the next.

C. Category C includes ornamental finishes that are applied to the base material defined by the

description of 5.2. The material is blackened or oxidized then relieved or highlighted.

D. Category D finishes are functional protective finishes and appearance is not a factor.

E. Category E finishes shall be equivalent in appearance when compared with the corresponding

Category A, B or C finishes. They shall be viewed using the method specified in 4.3.3.

4.2.1 BHMA provides certain Category A and Category B match plates including 605, 606, 611, 612,

613, 618, 619, 625, 626, 628, 629, and 630. Contact individual manufacturers for other finish samples.

Category B finish match plates shall be kept fresh and shall be considered so if not held over six months and

are kept in the original container and the viewing surface not touched.

4.3 Finishes

4.3.1 There are separate numbers for finishes as they are applied to each separate base material except

when brass or bronze is permitted to be used interchangeably without affecting the final finish, and with

some painted finishes which apply to several base materials.

4.3.2 All BHMA product types as described in the ANSI/BHMA A156 Series Standards are not available

in all finishes. Consult individual manufacturers' catalogs.

4.3.3 Test Methods for Finish Matching

4.3.3.1 Comparative finishes shall appear the same when viewed two feet apart and three feet away,

on the same relative plane.

8

4.3.3.2 Viewing Conditions. Place the specimen on a neutral background (middle gray to white) and

illuminate it with natural or artificial daylight in 4.3.3.3.

4.3.3.3 Light Source. The artificial daylight source shall approximate the color and spectral quality

of average daylight as represented by CIE illuminant D65 (as shown in appendix A) in accordance with

ASTM D 1729-96 (2003).

9

5. FINISH NOMENCLATURE AND CODE NUMBERS

5.1 Finish Nomenclature Finishes shall be specified using the categories listed in 4.2. A finish

designation with a letter suffix E indicates the finish code that the BHMA match plate is derived from.

Example: 605 means that all the significant surfaces are produced from the same base material (brass) that

the match plate is derived from. However 605E means that the finish is to be compared to the 605 match

plate for appearance only regardless of the base material or finish process used.

APPENDIX A USERS GUIDE

(NOT A PART OF ANSI/BHMA A156.18)

A1 FINISHING PROCESSES

A1.1 Blackened is a darkened surface usually produced by chemical or applied means.

A1.2 Bright is a reflective finish generally produced mechanically or chemically.

A1.3 Satin is a surface usually with a limited reflectivity produced mechanically with a fine scratch

pattern, which is straight, concentric, spiral or random. It is also produced electro-chemically with a non-

reflective surface. A grit size of 150 to 220 is typically used to obtain patterns similar to the BHMA

matchplates although results vary by material and process.

A1.4 Oxidizing is chemically changing the color of the base material in shades ranging from dark to

light.

A1.5 Relieving or highlighting is mechanically removing oxide or blackening from portions, usually

raised, of a patterned or textured surface thereby providing a two toned effect.

A1.6 Organic Coating Examples Coatings such as polyester, acrylic, lacquer, epoxy, or enamel in which

the principal ingredients are derived from some compound of carbon (excluding carbides).

A2 VIEWING FORMULA

A2.1 Variations in surface appearance of hardware products occur because of equipment used, the alloys

being finished or the processes performed in the finishing operations. For this reason, side by side

comparison testing is not realistic and the viewing formula given in 4.3.3 is used.

A3 Alternate Test method for Finish Matching. The following method is a more precise technique

which is being developed by BHMA for comparing finish match. Since it is in the development stage the

absolute values and tolerances may be different when adopted into the standard.

A3.1 Spectrophotometer/Colorimeter Test. Spectrophotometers and Colorimeters (hereafter referred to

as measuring equipment) can be used to determine finish match to the BHMA match plate when the match

test is conducted using the following guidelines.

a) Illumination. A light source representing CIE illuminate D65 should be used for all measurements

b) Observer Angle. The measuring equipment should be set for a 10 degree observer angle.

c) Specular Components. If the measuring equipment can have the specular component included or

excluded, the equipment should be set to include the specular component.

d) Aperture Size. The match plate and sample to be measured shall be sized such that it completely fills

the measuring equipment’s viewing aperture.

e) Measurement Scale. The measuring equipment must be capable of measuring the CIE L*a*b* method.

f) Averaging. If capable, the measuring equipment should be set to take several readings and average

their value. For surfaces that are not Bright (satin, relieved, etc.), the average should include readings where

the samples have been rotated 90 degrees (both match plate and comparison sample).

21

g) Other Settings. Other settings required by the measuring equipment should be set in accordance with

the manufacturer’s recommendations. These settings must be documented for each test. Procedures. Since

actual procedures may vary dependent upon the measuring equipment being used, the actual measuring

procedure/process must be documented for each test. All tests conducted on similar type finishes should be

conducted in a consistent manner. Deviations must be documented.

Unused proposals for US “de-emphasis”:

The use of nearest former US designations of finishes is anathema to the proper use of ANSI finish code numbers

contained in this Standard. While discouraging the use of these former US designations, the committee responsible

for this standard continued for several decades to print a column of “nearest former US equivalent” for each

ANSI/BHMA finish code numbers. This practice is discontinued with this revision. The committee determined that

printing such a column has in fact served to encourage the continued use of the US numbers in the jargon of a small

segment of our industry.

The “E” designation is loosely comparable to the former US numbers; that is, neither the base material, nor

process is specified. For the most predictable performance, specify Category A finishes; specifying finish soley

by US number is not recommended.
