This document specifies the requirements, methods of rating and testing of single, double, three and four leg welded chain slings of grade 8 using components such as sling chains according to ISO\u00c3\u201a\u00c2 3076<\/span><\/span>together with links according to ISO\u00c3\u201a\u00c2 16798<\/span><\/span>, hooks according to ISO\u00c3\u201a\u00c2 7597<\/span><\/span>and forged components according to ISO\u00c3\u201a\u00c2 8539<\/span><\/span>.<\/p>\n

\n
\n NOTE\u00c3\u201a\u00c2 1\n <\/div>\n

For special lifting purposes not covered by this document, additionally intermediate links can be used, for example to connect components to each other having different working load limit.<\/p>\n<\/div>\n

The range of nominal diameter, d<\/i>n<\/sub>, covered by this document is from 4\u00c3\u201a\u00c2 mm to 45\u00c3\u201a\u00c2 mm.<\/p>\n

Chain slings according to this document are for use in the temperature range \u00c3\u00a2\u00e2\u201a\u00ac\u00e2\u20ac\u015340\u00c3\u201a\u00c2 \u00c3\u201a\u00c2\u00b0C to +400\u00c3\u201a\u00c2 \u00c3\u201a\u00c2\u00b0C according to ISO\u00c3\u201a\u00c2 3056<\/span><\/span>.<\/p>\n

\n NOTE\u00c3\u201a\u00c2 2\n <\/div>\n

Concerning the use and maintenance of chain slings of grade\u00c3\u201a\u00c2 8, see ISO\u00c3\u201a\u00c2 3056<\/span><\/span> .<\/p>\n<\/div>\n

Chain slings according to this document comply with the general conditions of acceptance of ISO\u00c3\u201a\u00c2 1834<\/span><\/span>and are used for symmetrically distributed loads only.<\/p>\n

\n
\n NOTE\u00c3\u201a\u00c2 3\n <\/div>\n

For rating of chain slings with asymmetrically distributed loads, see ISO\u00c3\u201a\u00c2 3056<\/span><\/span> .<\/p>\n<\/div>\n

This document does not apply to mechanically joined chain slings.<\/p>\n
