Overview

ASTM D2564-20: Standard Specification for Solvent Cements for Poly(Vinyl Chloride) (PVC) Plastic Piping Systems provides detailed requirements for solvent cements used in joining PVC piping systems. Developed by ASTM International, this standard is critical for manufacturers, installers, and inspectors to ensure reliable and safe solvent-welded joints in PVC plumbing, irrigation, and industrial piping applications. The specification applies to solvent cements formulated for use with PVC pipe and fittings produced from compounds defined in ASTM D1784, ensuring compatibility, performance, and product consistency across the industry.

Key Topics

• Scope and Purpose

  • Defines requirements for solvent cements used for joining PVC piping systems.
  • Covers solvent cements intended for use with rigid PVC pipes and fittings as classified in ASTM D1784.
  • Specifies applicable joining methods, referring to Practice D2855 (two-step) and Practice F3328 (one-step).
  • Establishes standard measurement units (inch-pound as standard; SI units provided for information only).

• Product Requirements

  • Resin Content: Specifies a minimum PVC resin content.
  • Dissolution: Sets requirements for the cement's ability to dissolve PVC compound.
  • Viscosity Classification: Classifies cements as regular-bodied, medium-bodied, or heavy-bodied, each with defined minimum viscosity for different pipe sizes.
  • Bond Strength: Minimum lap shear strength and hydrostatic burst strength requirements ensure quality solvent-welded joints.

• Manufacturing Quality

  • Only clean and compatible rework material from the same manufacturer may be used.
  • The cement must be free of foreign matter, lumps, or gelation that could impact joint performance.
  • Requirements for labeling, lot traceability, and container markings support quality control and safety.

• Safety and Compliance

  • Solvent cements are manufactured from flammable liquids - proper handling and ventilation are vital.
  • For potable water applications, products must be evaluated for health effects per NSF/ANSI Standard 61 or NSF Standard 14 if required by regulatory authorities.

Applications

• Plumbing and Water Supply: Used to create leak-proof joints in residential, commercial, and industrial water distribution systems.
• Irrigation Systems: Essential for joining PVC pipes and fittings in agricultural and landscape irrigation setups.
• Industrial Piping: Facilitates secure connections in chemical and process piping systems using PVC pipes.
• Construction and Maintenance: Utilized by contractors and maintenance teams for new installation and repair of PVC piping networks.
• Potable Water Systems: When certified, ensures safe use in drinking water pipework.

Selection and Use: The standard provides guidance on selecting proper cement viscosity based on pipe size and joint type to achieve optimal performance. Manufacturers’ recommendations and joint fit conditions should always be followed for best results.

Related Standards

For comprehensive compliance and system compatibility, users of ASTM D2564-20 should also refer to these related standards:

• ASTM D1784: Rigid Poly(Vinyl Chloride) (PVC) Compounds and Chlorinated Poly(Vinyl Chloride) (CPVC) Compounds
• ASTM D2855: Practice for Two-Step Method of Joining PVC or CPVC Pipe and Piping Components

• ASTM D1785: Specification for PVC Plastic Pipe, Schedules 40, 80, and 120
• ASTM D2467: Specification for PVC Plastic Pipe Fittings, Schedule 80
• NSF/ANSI Standard 61 & 14: Drinking Water System Components - Health Effects and Plastic Piping Components and Related Materials
• ASTM F402: Practice for Safe Handling of Solvent Cements, Primers, and Cleaners Used for Joining Thermoplastic Pipe and Fittings

Conclusion

Adherence to ASTM D2564-20 ensures that solvent cements for PVC plastic piping systems meet rigorous safety, performance, and quality criteria. This standard supports robust, durable joints in a wide range of piping applications, helping industry professionals maintain compliance and ensure long-term system integrity.

have been found to make cements that are acceptable under the requirements of this specification.
NOTE 1—It is recommended that solvent cements made to this specification not be orange since that color is recommended for use with CPVC solvent
cement under Specification F493.

5.4 Lap Shear Strength—The minimum average lap shear strength, when tested in accordance with 6.3.2, shall be 250 psi (1.7
MPa) after a 2-h curing time, 500 psi (3.4 MPa) after a 16-h curing time, and 900 psi (6.2 MPa) after a 72-h curing time.

5.5 Hydrostatic Burst Strength—The minimum average hydrostatic burst strength, when tested in accordance with 6.3.3, shall be
400 psi (2.8 MPa) after a 2-h curing time.
6. Test Methods
6.1 Solids Content:
6.1.1 Apparatus:
6.1.1.1 Ointment Tins (Style No. 12, 1-oz (30-mL), all metal).
6.1.1.2 Vacuum. Oven
6.1.1.3 Analytical. Balance
6.1.1.4 Centrifuge.
6.1.2 Procedure:
6.1.2.1 Stir the sample thoroughly with a spatula before weighing (Note 4). Weigh 3.0 6 0.5 g of the sample to the nearest 1 mg
into a tared ointment tin. Place tin into the vacuum oven (Note 5), and heat at 248 °F (120 °C) for 45 min +15, −0 min. Discard
specimens left in for more than 1 h. The vacuum must be continually in operation to draw off flammable solvents and shall be
maintained at 15 mm Hg minimum. Remove the tin from the oven and place in a desiccator until cooled to room temperature.
Weigh the tin and dried sample to the nearest 1 mg.
NOTE 4—This material is usually nonhomogeneous and shall be thoroughly stirred before weighing. The weighing shall also be accomplished quickly
to avoid loss of solvent by volatilization.
NOTE 5—The use of a vacuum oven is mandatory for drying the specimen, because this oven has neither an exposed heating surface nor an open flame,
thus avoiding the danger of flashing. The oven also provides an open vacuum to exhaust solvent fumes.
6.1.2.2 After weighing, dissolve most of the dried sample by adding 15 mL of tetrahydrofuran (THF) to the sample in the ointment
tin and stirring with a glass rod for 15 min. Collect the liquid decanted from this step, plus the liquid from the next two steps.
Dissolve the remainder with a second addition of 15 mL of THF, followed by a third addition of 5 mL of THF to rinse the ointment
tin. Centrifuge the entire volume at 20 000 r/min for 15 min. Discard the supernatant liquid. Add 15 mL of THF to the tube, mix
thoroughly, and transfer the tube contents to the ointment tin. Use 2 mL more of THF to wash down the tube, and pour into the
ointment tin. Evaporate off the THF in the vacuum oven at 248 °F (120 °C) for 45 min. Cool in desiccator, weigh the tin to the
nearest 1 mg, and calculate the percent of inert filler present in the cement.
6.1.3 Calculation—Calculate the percentage of PVC resin as follows:

C = weight of tin and specimen before drying, and
D = weight of inert filler, if present.
NOTE 6—Other methods for determination of resin and inert filler content may be used provided the results of the alternative method are as accurate and
consistent as the above method.
6.2 Viscosity—Measure the viscosity in accordance with Method B of Test Methods D1084, except that conditioning to
temperature equilibrium only is required. For qualification purposes, use a Model RVF viscometer, a speed of 10 r/min, and the
spindle that, by trial, gives the closest reading to center range of scale for the cement being tested. Other speeds are also used for
quality control purposes.
6.3 Bond Strength:
6.3.1 Number of Specimens—A minimum of seven specimens shall be tested for the lap shear strength test (see 5.4). A minimum
of five specimens shall be tested for the hydrostatic burst stength test (see 5.4).
6.3.2 Lap Shear Strength:
6.3.2.1 Cut 1 by 1-in. (25 by 25-mm) and 1 by 2-in. (25 by 50-mm) sections from ⁄4-in. (6-mm) thick sheet made
