1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. With the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the "M" designation (SI) of the product specification is specified in the order.

Note 1--The dimensionless designator NPS (nominal pipe siz
e) is used in this standard for such traditional terms as "nominal diameter," "size,"" nominal bore," and "nominal size".

1.4 The following precautionary statement pertains only to the test method portion, Section 21, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
