These are provided for use when additional testing or inspection is desired and apply only when specified individually by the purchaser in the order. 1.3 In case of conflict between the requirements of the individual specification and this general specification, the former shall prevail. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
