This Standard establishes requirements for Sliding and Folding Door Hardware. Cycle tests@ abuse@ durability static load@ smoothness@ static friction@ kinetic fiction and finish tests are included. Hardware for light to very heavy doors is covered including both residential and industrial applications. Fire doors equipped with sliding door hardware shall successfully pass the requirements of ANSI/UL 10B or 10C. ANSI/UL 14B specifies requirements for sliding door hardware used on sliding type fire doors. Tests described in this Standard are performed under laboratory conditions. In actual usage@ results vary because of installation@ maintenance and environmental conditions. All dimensions which do not carry specific tolerances or are not marked maximum or minimum are permitted to have nominal deviations. Dimensions are given in US units. SI unit (metric) equivalents given in parentheses are approximate. ANSI Standards referenced in this Standard are available from the BHMA website www.buildershardware.com or the American National Standards Institute@ 11 West 42nd Street@ New York@ NY 10036.
