Tolerance of length
The length (L) should be measured between the "bearing points" or the circumference for endless slings.

The length on each leg should be nominal length with a tolerance of -0/+2 chain link lengths.

The difference in length (usally the same for all legs) between the shortest and longest leg in a mulit-leg sling, assembled with connecting links, should not exceed 10 mm if the sling is 2 m or less, for longer slings a value of 5 mm per metre should be used.
