Full Description

1.1This specification covers the requirements and method of rating and testing for alloy chain slings. Slings shall be assembled using components manufactured in accordance with Specification A391/A391M for Grade 80 chain, Specification A973/A973M for Grade 100 chain, and Specification A952/A952M for other components. This specification covers welded and mechanically assembled slings.

1.2This specification does not cover slings used at elevated temperatures (above 400F [200C]), in harmful or corrosive environmental conditions or for applications such as nonsymmetrical legs or loading.

1.3This specification is a performance and assembly specification. Other standards, such as OSHA 1910.184, ASME B30.9, and ASME B30.10, apply to the use of the products in this specification.

1.4The 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 are not exact equivalents; therefore each system shall be used independently of the other, without combining values in any way.
