ASTM A999/A999M-04a
(Specification)Standard Specification for General Requirements for Alloy and Stainless Steel Pipe
Standard Specification for General Requirements for Alloy and Stainless Steel Pipe
SCOPE
1.1 This specification covers a group of general requirements that, unless otherwise specified in an individual specification, shall apply to the ASTM product specifications noted below.
1.2 In the case of conflict between a requirement of a product specification and a requirement of this specification, the product specification shall prevail. In the case of conflict between a requirement of the product specification or a requirement of this specification and a more stringent requirement of the purchase order, the purchase order shall prevail.
1.3 The values stated in either 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 are not exact equivalents; therefore each system is to be used independently of the other without combining values in any way. The inch-pound units apply unless the "M" designation (SI) of the product specification is specified in the order.
Note 1—The dimensionless designator NPS (nominal pipe size) 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 22, 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.
