(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 are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two system shall not be combined.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
