19、 to severalof the above product specifications as indicated therein. Such requirements are provided for use if additional testing or additionalrestrictions are required by the purchaser, and apply only if specified individually in the purchase order.1.2 Appendix X1 provides information on coil as a

23、 thatsuch requirements do not negate any of the requirements of this general requirements specification or the applicable productspecification.1.9 For purposes of determining conformance with this general requirements specification and the applicable productspecification, values are to be rounded to
24、 the nearest unit in the right-hand place of figures used in expressing the limiting valuesin accordance with the rounding method of Practice E29.1.10 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in eachsystem may not be exact
25、equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.1.11 This general requirements specification and the applicable product specification are expressed in both inch-pound units andSI units;
