Anotace textu normy ASTM F949-20 :
This specification covers the requirements, test methods, and materials for 4 to 36-in. diameter poly(vinyl chloride) (PVC) corrugated pipes, joints, and fittings that consist of an outer corrugated wall fused to a smooth inner wall, and are suitable for underground use in nonpressure applications for sanitary sewers, storm sewers, and perforated and unperforated pipes for subdrainage. When evaluated by the test procedures enumerated herein, the products shall conform to dimensional and performance requirements as specified for pipe stiffness, flattening resistance, impact strength, extrusion quality, heat reversion, bond strength, and joint tightness.

1.1 This specification covers requirements, test methods, and materials for 4 to 48 in. diameter poly(vinyl chloride) (PVC) corrugated pipe with a smooth interior. This profile wall pipe consists of an outer corrugated wall fused to a smooth inner wall providing pipe stiffness levels of 46 psi and 115 psi. Joints and fittings are included in this specification. 1.2 The requirements of this specification are intended to provide pipe and fittings suitable for underground use in nonpressure applications for sanitary sewers, storm sewers, and perforated and unperforated pipes for subdrainage. Note 1: Industrial waste disposal lines should be installed
only with the specific approval of the cognizant code authority,
since chemicals not commonly found in drains and sewers and
temperatures in excess of 140 °F (60 °C) may be
encountered.
1.3 Pipe and fittings produced to this specification shall be installed in accordance with Practice D2321. Note 2: For perforated pipe applications, the size of the
embedment zone and permeability of the embedment material are
important to the system's ability to provide the desired level of
infiltration or exfiltration. The gradation of the embedment
material must be compatible with the perforation slot size to avoid
backfill migration into the pipe.
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 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. 1.6 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. |
