Code information

A number of model building codes require independent, third-party certification of PVC pipe against the criteria of nationally and internationally accepted physical property and general performance standards of organizations such as the American Water Works Association (AWWA), the American Society for Testing and Materials (ASTM) and NSF International. For specifiers as well as building owners and managers, that means every foot of PVC pipe will be as strong, durable, safe and reliable as every other. And there are dozens of manufacturers across the country making PVC pipe according to these standards. This allows localized and efficient specification of PVC pipe and ensures ready availability of product.

Relevant standards.

Drain, Waste and Vent Systems. PVC pipe conforms to either ASTM D 2665, which specifies the requirements for solid wall Schedule 40 pipe; ASTM D 2949, which specifies 3.25-inch outside diameter pipe and fittings; or ASTM F 891, which specifies the requirements for Schedule 40 pipe having a cellular core.

•PVC tube and tubular fittings conform to ASTM F 409. Solid wall PVC pipe fittings conform to ASTM D 2665 or CSA CAN/CSA B181.2.
 
•Drainage pattern fittings conform to ASTM D 3311. And solvent cements for PVC conform to ASTM D 2564.

•For the purposes of quality control, pipe and fittings for this application conform to the ANSI/NSF 14 standard.

Hot and Cold Water Distribution Systems. CPVC SDR 11 (CTS) pipe and fittings conform to requirements of ASTM D 2846 or CSA CAN/CSA B137.6.

•Schedule 40 and 80 pipe conform to the requirements of ASTM F 441. SDR-PR pipe conforms to requirements of ASTM F 442.

•Schedule 40 socket fittings conform to ASTM F 438. Schedule 80 socket fittings conform to ASTM F 439, as do solvent cements for CPVC.

•For the purposes of quality control, pipe and fittings for this application conform to the ANSI/NSF 14 and 61 standards.
 
Water Service Systems. Schedule 40, Schedule 80 or Schedule 120 PVC pipe conform to ASTM D 1785 or CSA CAN/CSA B137.3.

•PVC pipe having a wall thickness of SDR 13.5, SDR 17, SDR 21, SDR 26, SDR 32.5, SDR 41 or SDR 64 conforms to ASTM D 2241.

•PVC pipe having a wall thickness of DR 14, DR 18 or DR 25 conforms to AWWA C900 or AWWA C905.

•PVC Schedule 40 fittings conform to ASTM D 2466 or CSA CAN/CSA B137.3.

•For the purposes of quality control, pipe and fittings for this application conform to the ANSI/NSF 16 and 61 standards.

Code information. Model plumbing codes sponsored by associations of enforcement officials or other industry groups are the basis for most of the more than 14,000 local codes in the United States. Every model plumbing code in the United States approves the use of PVC pipe.

PVC pipe is permitted to be used in any water service system, without limitation, in the National Plumbing Code (Building Officials and Code Administrators International), Uniform Plumbing Code (International Association of Plumbing and Mechanical Officials), National Standard Plumbing Code (Plumbing-Heating-Cooling Contractors Association) and Standard Plumbing Code (Southern Building Code Congress International).

PVC pipe is also permitted to be used in any sanitary drain, waste and vent system and storm drainage system as above. CPVC pipe is permitted to be used in any hot and cold water distribution system, without limitation. In fact, it is also permitted in the One & Two Family Dwelling Code (International Code Council).

PVC pipe – like all plastic pipe products – must meet strict requirements for safety and performance. PVC piping systems have been certified to national standards by qualified, independent certifiers for more than 40 years.
