Anotácia textu normy ASTM D2997-21 :
This specification covers machine-made glass-fiber-reinforced thermosetting-resin pressure pipe manufactured by the centrifugal casting process. Pipe covered by this specification has been found suitable for conveying gases, petroleum products, or corrosive fluids. For the purposes of this standard, polymer does not include natural polymers. Pipe meeting this specification shall be categorized by the prescribed long-term static or cyclic hydrostatic design basis when tested. Additionally, the pipe shall meet the applicable cell limit requirements for short-term rupture strength, longitudinal tensile strength, tensile modulus, and pipe stiffness.

1.1?This specification covers machine-made glass-fiber-reinforced thermosetting-resin pressure pipe manufactured by the centrifugal casting process. Included are a classification system and requirements for materials, mechanical properties, dimensions, performance, test methods, and marking. Note 1:?The term fiberglass pipe as described in Section
3 applies to both reinforced
thermosetting resin pipe (RTRP) and reinforced polymer mortar pipe
(RPMP).
Note 3:?For the purposes of this standard, polymer does not
include natural polymers.
1.2?The values given in parentheses are for information only. Note 4:?There is no known ISO equivalent to this
standard.
1.3?The following precautionary caveat pertains only to the test method portion, Section 7, 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. 1.4?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. |
