The graph below shows a stress/strain diagram comparing Reilloc's ULTRASPEC 2000 (Graph A) with DIN 22 252 (Graph B). The area under the graph is a measure of a chain's durability and is used by some customers as an energy absorption factor. The increased energy absorption factor of ULTRASPEC 2000 can be seen from the blue area on the diagram. Reilloc's higher test force at 1.4% maximum total elongation compared with the DIN 22 252 value at 1.6% maximum extension is also shown.
