LTDS =Tult (RFୈ)(RF୍ୖ)(RFୈ) where:
LTDS = Long Term Design Strength Tult = Ultimate strength RFCR = Reduction factor for creep RFIR = Reduction factor for installation damage RFD = Reduction factor for durability
The minimum reduction factors are as follows:
R F CR = 2.6 for HDPE, 4.0 for PP, 1.6 for PET 110 R F IR = 1.10 RF D = 1.10
