CS 22.613  Material strength properties and design values

CAA ORS9 Decision No. 1

(a) Material strength properties must be based on enough tests to establish design values on a statistical basis. 

(b) The design values must be chosen so that the probability of any structure being understrength because of material variations is extremely remote. (See AMC 22.613(b)) 

(c) Where the temperature attained in an essential component or structure in normal operating conditions has a significant effect on strength, that effect must be taken into account. (See AMC 22.613(c))
