Over deze norm
1.1 This practice describes a procedure for making joints with poly(vinyl chloride) plastic (PVC) pipes, both plain ends and fittings, and bell ends, by means of solvent cements. These procedures are general ones for PVC piping. In non-pressure applications, simplified procedures may be used. Manufacturers should supply specific instructions for their particular products, if and when it seems necessary.
1.2 The techniques covered are applicable only to PVC pipe, both plain and bell-end, and fittings of the same classes as described in Specification D1784.
1.3 Pipe and fittings are manufactured within certain tolerances to provide for the small variations in the extrusion, belling, and molding processes and are not to exact size. A partial list of standards for PVC pipe, fittings, and cements suitable for use in making solvent-cemented joints is given in Appendix X1.
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 text of this practice references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the practice.
1.6 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.
