The ultimate elongation of uncoated chains (in their natural state) is not less than 25%.
The ultimate elongation of chains with surface treatment is not less than 20%.
The ratio of the carrying capacity to the trial load to the destructive load is 1:2, 5:4, respectively.
The value of the allowable carrying capacity of chains varies depending on the range of operating temperatures according to DIN 818-6.
