AS 3775.1-2004 specifies requirements for chain slings using Grade T chain complying with AS 2321.

This Standard specifies requirements for chain slings using Grade T chain complying with AS 2321. NOTES: 1 AS 2321 specifies chain in terms of the ISO quality grade designation system. The ISO system also permits Grade T to be designated as Grade 8. 2 Guidance on information that should be supplied with enquiries and orders is given in Appendix A. 3 Recommendations for the care and use of Grade T chain slings are published as AS 3775.2. 4 Standards for components that are used in lifting systems are listed in Appendix B.
