Standard Specification for General Requirements for Alloy and Stainless Steel Pipe
|Publication Date:||1 March 2018|
|ICS Code (Iron and steel pipes):||23.040.10|
This specification2 covers a group of general requirements that, unless otherwise specified in an individual specification, shall apply to the ASTM product specifications noted below.
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.
The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. 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. 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."
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
