(Specification)Standard Specification for Polyvinylidene Fluoride (PVDF) Corrosive Waste Drainage Systems
Standard Specification for Polyvinylidene Fluoride (PVDF) Corrosive Waste Drainage Systems
ABSTRACT
This specification covers requirements for polyvinylidene drainage systems for corrosive applications. Requirements for material, pipe and fittings are included. Polyvinylidene fluoride includes emulsion/suspension polymerization and copolymers of vinylidene fluoride/hexafluoropropylene produced by either method. These requirements apply to Schedule 40 and 80 IPS and SDR 21 pipe sizes. Pipe and fittings are to be joined by heat fusion or mechanical methods. The following tests shall be performed: chemical resistance; water absorption; joint tests— hydrostatic pressure tests; mechanical joint pullout test; threads; flattening; and impact resistance for PVDF pipe and fittings.
SCOPE
1.1 This specification covers requirements for polyvinylidene drainage systems for corrosive applications. Requirements for material, pipe and fittings are included. Polyvinylidene fluoride includes emulsion/suspension polymerization and copolymers of vinylidene fluoride/hexafluoropropylene produced by either method.
1.2 These requirements apply to Schedule 40 and 80 IPS and SDR 21 pipe sizes. Pipe and fittings are to be joined by heat fusion or mechanical methods using the equipment supplied by the manufacturers.
1.3 This specification is not intended to provide for interchangeability between plastic pipe and fittings from different manufacturers, but it does allow for transition fittings for joining one manufacturer's product to another's product, provided the joining technique used is other than heat fusion.
1.4 This specification is not for polyvinylidene pressure systems.
1.5 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.
1.6 Notes and appendixes are not a mandatory part of this specification.
1.7 The following safety hazard caveat pertains only to the test method portion, Section 8, 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.

TABLE 2 Wall Thicknesses and Tolerances for PVDF Pipe Schedules 40 and 80 and SDR 21, in. (mm)
NOTE 1— For fittings, the wall thickness is a minimum value, except that a 10% variation resulting from core shift is allowable. In such a case, the

6.1.2.6 The patterns, dimensions, and laying lengths of molded fittings, including adaptors, shall meet the requirements of
Specification D3311, or shall be of a proven design and allow a smooth transition of fluid flow from one direction to another.
6.1.2.7 Cleanouts, cleanout plugs, and caps as commonly used in the manufacturer’s laboratory drainage system, shall have a
thread size and depth sufficient to ensure that the minimum waterway sizes are maintained.
6.1.2.8 Traps—All traps shall have a minimum water seal of 2 in.
6.2 Chemical Resistance—Pipe and fittings material shall be evaluated in accordance with Practice D543, Procedures I and II,
using the chemicals listed in 8.3. The weight change shall not exceed 2%, nor shall the apparent tensile strength change by more
than 10%. In cases where there is a change in the apparent tensile strength greater than 10%, a further evaluation shall be made
after removal from the chemical and conditioning for 72 h. If there is a minimum of 50% recovery of tensile strength after 72 h,
and that figure is within 610% of the original tensile strength, the specimen shall be considered acceptable.
6.3 Water Absorption—Pipe and fitting materials shall not change in weight more than 0.50% when tested in accordance with
8.4.

NOTE 1—Mechanical joints include transition, compression, threaded, and other type mechanical joints.
6.4.3 Mechanical joints shall incorporate a positive mechanical system for axial restraint in addition to any restraint provided
by friction.
