Standard Practice for the Two-Step (Primer and Solvent Cement) Method of Joining Poly (Vinyl Chloride) (PVC) or Chlorinated Poly (Vinyl Chloride) (CPVC) Pipe and Piping Components with Tapered Sockets

ASTM Vol.08.04 (2023)

This practice describes a two-step (primer and solvent cement) method of joining poly(vinyl chloride) (PVC) or chlorinated poly(vinyl chloride) (CPVC) pipe and piping components with tapered sockets. NOTE 1: Simplified procedures may be allowed in non-pressure applications where local codes permit. NOTE 2: Where conflicts occur between the code and the manufacturer’s installation instructions, the more restrictive provisions apply. The products covered by this practice are intended for use with the distribution of pressured 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 3: Pressurized (compressed) air or other compressed gases contain large amounts of stored energy which present serious safety hazards should a system fail for any reason. This standard practice does not address the one-step method of joining pipe and piping components with tapered sockets with solvent cement without the use of primer. For the one-step method see Practice F3328The techniques covered are applicable to joining PVC to PVC or CPVC to CPVC pipe and piping components with tapered sockets. In the remainder of this standard practice, the term “piping components with tapered sockets”, whether it be bell end pipe, spigot connections, or any other type of tapered connections, will be referred to as “fittings.”
