Anotace textu normy ASTM D1785-21a :
This specification covers poly(vinyl chloride) (PVC) plastic pipe, schedules 40, 80, and 120 for use with the distribution of pressurized liquids only. This specification also includes classification criteria, nomenclature system, test methods, requirements, workmanship, dimensions, sustained pressure, burst pressure, flattening, extrusion quality, finish, appearance, and marking methods for PVC plastic pipe. PVC pipe covered are marked with one of six type/grade/design stress designation and defined by four hydrostatic design stresses. PVC plastics are categorized by short-term and long term-strength tests.

1.1?This specification covers poly(vinyl chloride) (PVC) pipe made in Schedule 40, 80, and 120 sizes and pressure-rated for water (see Appendix X1). Included are criteria for classifying PVC plastic pipe materials and PVC plastic pipe, a system of nomenclature for PVC plastic pipe, and requirements and test methods for materials, workmanship, dimensions, sustained pressure, burst pressure, flattening, and extrusion quality. Methods of marking are also given. 1.2?The products covered by this specification are intended for use with the distribution of pressurized liquids only, which are chemically compatible with the piping materials. Due to inherent hazards associated with testing components and systems with compressed air or other compressed gases some manufacturers do not allow pneumatic testing of their products. Consult with specific product/component manufacturers for their specific testing procedures prior to pneumatic testing. Note 1:?Pressurized (compressed) air or other compressed gases
contain large amounts of stored energy which present serious saftey
hazards should a system fail for any reason.
Note 2:?This standard specifies dimensional, performance and
test requirements for plumbing and fluid handling applications
only. It does not include provisions for the use of these products
for venting of combustion gases. UL 1738 is a standard that does
include specific testing and marking requirements for flue gas
venting products, including PVC.
1.3?The text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification. 1.4?The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5?The following safety hazards caveat pertains only to the test methods portion, Section 8, 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.A specific precautionary statement is given in Note 9. Note 3:?CPVC plastic pipes, Schedules 40 and 80, which were
formerly included in this specification, are now covered by
Specification F441/F441M.
Note 4:?The sustained and burst pressure test requirements,
and the pressure ratings in the Appendix X1, are calculated from stress
values obtained from tests made on pipe 4 in. (100 mm) and smaller.
However, tests conducted on pipe as large as 24 in. (600 mm)
diameter have shown these stress values to be valid for larger
diameter PVC pipe.
Note 5:?PVC pipe made to this specification is often belled
for use as line pipe. For details of the solvent cement bell, see
Specification D2672 and for
details of belled elastomeric joints, see Specifications
D3139 and D3212.
1.6?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. |
