1.2 One or more of Sections 1.3, 5, 6, 17, 18, 19, 20, 21, 22, and 23 apply when the product specification or purchase order has a requirement for the test or analysis described by these sections.

1.3 In case of conflict between a requirement of the product specification and a requirement of this general requirement specification only the requirement of the product specification need be satisfied.

1.4 The values stated in eithe inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. the values Stated in each system must be used independently of the other. combining values from the two systmes may result in nonconformance with the specification. the inch-pound units shall apply unless the "M" desigantion (SI) of the product specification is specified in the order.
