(Specification)Standard Specification for Weldless Chain
Standard Specification for Weldless Chain
ABSTRACT
This specification covers weldless chain suitable for applications where a light and flexible chain is required. The material may be steel, brass, or bronze. The chain shall conform to the dimensional requirements as specified. Breaking force test shall be made to conform to the minimum requirements specified.
SCOPE
1.1 This specification covers weldless chain suitable for applications where a light and flexible chain is required. The material may be steel, brass, or bronze.
1.2 Seven classes of chain are covered:
1.2.1 Class SL—Single-loop chain.
1.2.2 Class DL—Double-loop chain.
1.2.3 Class SH—Sash chain.
1.2.4 Class SF—Plumbers' chain.
1.2.5 Class SJ—Single-jack chain.
1.2.6 Class DJ—Double-jack chain.
1.2.7 Class RG—Register chain.
1.3 The values stated in either SI units or in other units shall be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way.
