Paragraph 4 Tensile testI1

Tensile tests shall be made on samples of stampings or pressings taken at random from any consignment. The result of the tensile test shall conform to the following conditions—

• Yield Stress.—Not less than 231.6 N/mm ².

• Ultimate Tensile Stress.—Not less than 463.3 N/mm ².

• Elongation on 50 mm gauge length.—Not less than 25%.

Note.—When the gauge length is less than 50 mm the required elongation shall be proportionately reduced.

The fractured test piece shall be free from piping and other defects (see paragraph 3 of this Part of this Schedule).
