Standard Specification for Polybutylene (PB) Plastic Pipe (SIDR-PR) Based on Controlled Inside Diameter (Withdrawn 2003)

SCOPE
1.1 This specification covers polybutylene (PB) pipe that is inside diameter controlled, made in standard thermoplastic pipe dimension ratios, and pressure rated for water (see appendix). Included are criteria for classifying PB plastic pipe materials and PB plastic pipe; a system of nomenclature for PB plastic pipe; and requirements and test methods for materials, workmanship, dimensions, sustained pressure, and burst pressure. Methods of marking are also given.  
1.2 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.  
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.
1.4 The following safety hazards caveat pertains only to the test methods 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 and health practices and determine the applicability of regulatory limitations prior to use.

The minimum is the lowest wall thickness of the pipe at any cross section. The maximum permitted wall thickness, at any cross section, is the minimum wall thickness
plus the stated tolerance. All tolerances are the plus side of the minimum requirement.
B
The 2 ⁄2to 6-in. pipe with a pressure rating of 0.69 MPa (100 psi) is not included.
