The finished material must be free from all internal and surface defects, such as cracks, seams, flakes, pipe and segregation. Dimensional tolerances must be in accordance with the standard. The finished product must be subjected to check analysis. 1387:1967 specifies the general requirements for material supply. The material must be tested to ensure that it complies with the requirements of the standards.

TESTS

The following tests shall be carried out in accordance with the method prescribed.
