1.2 The chemical composition, physical and mechanical properties, and all other requirements not included in this specification are prescribed in the product specification.

1.3 The values stated in inch-pounds units or SI units are to be regarded separately in the standard. Within the text the SI values are given in brackets. The values stated in each system of units are not exact equivalents; each system is independent of the other.
