A. Maximum tensile strength of the coating: minimum guaranteed value of 1,500 psi (10,500 kPa).
B. Final elongation: minimum 400%.
C. Accelerated Aging Test: The tensile strength and ultimate elongation of the vulcanized rubber compound were tested with oxygen at a pressure of 300 psi +/- 10 psi (2100 kPa +/- 70 kPa) and a temperature of 70 degrees Celsius +/ -1 degree (158 ºF +/- 18 ºF) for a period of 96 hours, after which the rubber properties are at least 60% of the original values.
