◎ The values given in this table are the mean values of the scatter band so far obtained, which will be checked from time to time as further test results become available and if necessary corrected.
◎ * 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.
