Zusatzinformation
Acc. to DIN 22252 / DIN 22255 final testing is carried out in “natural black” conditions, before any coating is applied. The breaking force and ultimate elongation values therefore apply in “natural black” condition. Each coating reduces the breaking force of the JDT chains up to 10% and the ultimate elongation by as much as 20% when compared with a chain in “nature black” condition.
