2021-1-27 · Typical permanent elongation values: Polyamide (P): 1,0-2,5%, Polyester (E): 0,5-1,5%, Aramide (D): 0,25-0,75%, Steel: 0,1-0,25%. Other (static) tests, e.g. as per DIN 22102, require a reference tension of 10% of the nominal belt breaking strength. The maximum total elongation for EP belts is 1,5, 2,5 or 3,0 %, depending on belt class.
