36.—(1) In paragraph 37, the following symbols have the following meanings—
(a)Re/t, yield limit, indicates the value at the calculation temperature of—
(i)the upper flow limit for a material presenting upper and lower flow limits,
(ii)the 1.0 % proof strength of austenitic steel and non-alloyed aluminium,
(iii)the 0.2 % proof strength in other cases.
(b)Rm/20 indicates the minimum value of the ultimate tensile strength at 20oC.
(c)Rm/t designates the ultimate tensile strength at the calculation temperature.
