◎ * and () indicate values of extended stress extrapolation or time extrapolation, respectively.
① This is the stress relative to the initial cross- section leadina to a permanent elongation of 1 % after 10000 h and 100000 h.
② This is the stress relative to the initial cross- section leading to fracture after 10000 h, 100000 h and 200000 h.
