ASTM A906/A906M-99

Standard Specification for Grade 80 and Grade 100 Alloy Steel Chain Slings for Overhead Lifting

SCOPE
1.1 This 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, A 973/A973M for Grade 100 chain, and A952/A952M for components. This specification covers welded and mechanically assembled slings.
1.2 This specification does not cover slings used at elevated temperatures (above 400°F [200°C]), in harmful or corrosive environmental conditions or for applications such as nonsymmetrical legs or loading.
1.3 This 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.
1.4 The values stated in either inch-pound units or SI units shall be regarded 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.
