(Specification)Standard Specification for Machine and Coil Chain
Standard Specification for Machine and Coil Chain
ABSTRACT
This specification covers welded carbon steel machine chain and coil chain. Although these chains are not intended for pocket wheel use, they can be used for pocket and sprocket wheel use. There are two classes each of machine and coil chain: class MS which are machine, straight-link steel chains; class MT which are machine, twist-link steel chains; class CS which are coil, straight-link chains; and class CT, which are coil, twist-link steel chains. The steel shall be made by the open-hearth, electric-furnace, or basic-oxygen process. Classes MS, MT, CS, and CT shall be electric welded. All chain in classes MS and CS shall be subjected to proof test and all chain classes shall undergo a breaking force test.
SCOPE
1.1 This specification covers welded carbon steel machine chain and coil chain. Although these chains are not intended for pocket wheel use, they can be used for pocket and sprocket wheel use. This chain shall never be used for overhead lifting applications.
1.2 There are two classes each of machine and coil chain:
1.2.1 Class MS—Machine, straight-link steel chain,
1.2.2 Class MT—Machine, twist-link steel chain,
1.2.3 Class CS—Coil, straight-link chain, and
1.2.4 Class CT—Coil, twist-link steel chain.
1.3 The values stated in either inch-pound units or SI units shall be regarded separately as standard. Within the text, the SI units are shown in brackets. 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.

manufacture, has been found by representative testing to break when a constantly increasing force is applied in direct tension.

3.1.2 lotlot, n—for the purpose of acceptance testing, a lot shall consist of 3000 ft [1000 m], or fraction thereof, of the same
grade and size chain. If a continuous length of chain exceeds 3000 ft [1000 m], it shall also be considered a lot.
