This specification covers requirements and method of rating and testing for alloy chain slings. Only component parts compatible with alloy chain shall be used. Sling assembled by welding shall be fabricated by the electric or gas welding process, or both. The material shall undergo proof test to meet the prescribed mechanical requirements. Several grades of alloy chain sling shall conform to the specified working load limit values.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, Specification A973/A973M for Grade 100 chain, and Specification A952/A952M for other 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 are to be regarded separately as standard. Within the text, the SI units are shown in brackets. 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 systems shall not be combined.1.5 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.

This specification covers forged alloy steel lifting components and welded coupling and master links for Grade 80 and Grade 100 alloy chain slings. The steel materials shall be melt processed either by electric process or oxygen blown process. The steel shall be fully killed and shall conform to the required austenitic grain size. Product analysis shall be performed on and the steel specimens shall conform to the required chemical compositions of nickel, chromium, molybdenum, phosphorus and sulfur. Proof tests shall be performed and the materials shall conform to the required values of working load and breaking force. Deformation test, breaking force test and fatigue test shall be performed on the steel materials.1.1 This specification covers the requirements for forged alloy steel lifting components and welded coupling and master links for Grade 80 and Grade 100 alloy chain slings as described in Specification A906/A906M.1.2 Two grades of components and welded links are covered:1.2.1 Grade 80.1.2.2 Grade 100.1.3 This specification is a performance standard. Other standards apply to use of these products. Some of these standards are: OSHA 1910.184, ASME B30.9, and ASME B30.10.1.4 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. 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 systems shall not be combined.1.5 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.

1.1 This specification covers insulating lifting links used for protection of workers positioning a load from accidental contact of the load lifting equipment with live electrical conductors, apparatus, and circuits.1.2 This specification includes design, material, and testing requirements for the manufacturer and in-service inspection, testing and care requirements for the user or the agent of the user.1.3 Insulating links whose primary application does not pertain to power line electrical safety are not within the scope of this specification.1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 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.
