1.1 This specification establishes materials, performance requirements, test methods, workmanship, dimensions, inspection, retest, and marking for polybutylene (PB) tubing products intended for exposed and undergound service in the delivery of irrigation water with maximum working pressures of 110 psi (0.76 MPa) at 73°F (23°C) and 75 psi (0.52 MPa) at 140°F (60°C) for DR 17 tubing, and 90 psi (0.62 MPa) at 73°F (23°C) and 60 psi (0.41 MPa) at 140°F (60°C) for DR 21 tubing, both inside diameter-controlled. 1.2 This specification defines tubing only, that is, a hollow cylinder having no special shape or multiple channels. 1.3 The values stated in parentheses are provided for information only. 1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
