RPo,*: 0.2 % proof stress; R,: tensile strength; A: percentage elongation after fracture on original gauge length L, =5,65& (where So is the original cross-sectional area); KV: impact strength of IS0 V-notch test pieces; e: thickness of test piece, in millimetres. 1) 1 N/mm2 = 1 MPa 2) The use of a test piece 200 mm long, elongation being measured on a gaugelength of 50 mm across the fracture, is permitted. However, in cases of dispute, only those results obtained on a proportionaltest piece shall be used. 3) Average of three tests; no individual result shall be less than 70 % ofthe specified minimum average value.
