ANSI BHMA-A156:2015 pdf download.AMERICAN NATIONAL STANDARD FOR CABINET HARDWARE
1. SCOPE
1.1 This Standard contains requirements for cabinet hardware and includes hinges, knobs, pulls, catches,shelf rests, standards and brackets, drawer slides, rotating shelves and track with guides for sliding panels.Included are performance tests covering operational, cyclical, strength, and finish criteria.
1.2 Tests described in this Standard are performed under laboratory conditions. In actual usage results vary because of installation, maintenance and environmental conditions. Tests required are applicable to hardware products only and are not intended to evaluate systems incorporating cabinet components.Fixtures described are designed to withstand the test forces required and only hardware items are measured.
1.3 Grade qualifications Manufacturers shall indicate the grade level of their products. Cabinet hardware shall meet all tests for the grade listing. Three grades are offered for most products; for drawer slides, additional grades 1HD are available.
3.1 Values Required values in this Standard are given in US units. SI (metric) units are shown in parentheses and are approximate.
3.2 Finishes All products shall meet the applicable performance requirements for finishes. A product with a finish not specifically described shall be acceptable if such finish meets or exceeds the lowest finish resistance requirements for that product class.
3.3 Lubrication
No lubricants shall be added before or during tests unless called for in the manufacturers' printed instructions supplied with the product. It is permitted to add lubricants during the manufacturing process.
3.4 Equipment It is important to ensure that test units are adequately secured to prevent tipping under all test loads.
3.5 Reference to other Standards American National Standards referred to in this Standard are available from American National Standards Institute, Inc., 11 West 42nd Street New York, NY 10036 or www.buildershardware.com.
3.6 Several requirements in this Standard were extracted in whole or part, with permission, from the BIFMA X5.5 1998, Desk Product Standard.
4.1.4 The test door with the hinges shall be mounted to a solid metal member that simulates the hinge side of the cabinet face frame and the test door shall be able to operate freely through at least 90 degrees.The hinge shall be aligned and spaced to eliminate hinge bind.
4.1.5 A separate set of hinges shall be used for the Hinge Permanent Set Test, the Hinge Operating Life Test and the Concealed Hinge Over Opening Test.
4.1.6 A dial indicator shall be used to measure vertical permanent set and vertical sag. This indicator shall be located as shown in Figures 1 and 2 and is identified as Indicator 1 on Figure 2.
4.1.7 When testing Grade 1 hinges, a second dial indicator shall be used to measure horizontal permanent set and horizontal sag. The indicator shall be located opposite the upper hinge as shown in Figures 1 and 2 and is identified as Indicator 2 on Figure 2. Exception: With top and bottom pivot type hinges, Indicator 2 shall be centered % in. (12.7 mm) from the top of the door.ANSI BHMA-A156 pdf download.
