Standard Specification for Chlorinated Poly(Vinyl Chloride) (CPVC) Plastic Hot- and Cold-Water Distribution Systems

ABSTRACT
This specification covers requirements, test methods, and methods of marking for chlorinated poly(vinyl chloride) plastic hot- and cold-water distribution system components made in one standard dimension ratio and intended for water service up to a certain temperature. These components comprise pipe and tubing, socket-type fittings, street fittings, plastic-to-metal transition fittings, solvent cements, and adhesives. The components are intended for use in residential and commercial, hot and cold, potable water distribution systems. The products covered by this specification are intended for use with the distribution of pressurized liquids only, which are chemically compatible with the piping materials. CPVC 4120 pipe, tubing, and fittings shall be classified by a single standard dimension ratio which shall be SDR 11, by a certain maximum continuous use temperature and by a certain diameter range for nominal pipe or tubing. CPVC plastic-to-metal transition fittings intended for use up a certain temperature are classified on the basis of resistance to failure by thermocycling. The chlorinated poly(vinyl chloride) plastics are categorized by two criteria: basic short-term properties and long-term hydrostatic strength. These short-term properties include mechanical strength, heat resistance, flammability, and chemical resistance which shall be determined after performing different tests. A test shall also be conducted in order to determine the long-term hydrostatic strength of CPVC 41 pipe, tubing, and fittings.
SCOPE
1.1 This specification covers requirements, test methods, assembly, and methods of marking for chlorinated poly(vinyl chloride) plastic hot- and cold-water distribution system components made in one standard dimension ratio and intended for water service up to and including 180 °F (82 °C). These components comprise pipe and tubing, socket-type fittings, street fittings, plastic-to-metal transition fittings, solvent cements, and adhesives. Requirements and methods of test are included for materials, workmanship, dimensions and tolerances, hydrostatic sustained pressure strength, and thermocycling resistance. The components covered by this specification are intended for use in residential and commercial, hot and cold, potable water distribution systems.  
1.2 The products covered by this specification are intended for use with the distribution of pressurized 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 1: 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.  
1.3 The text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
Note 2: Suggested hydrostatic design stresses and hydrostatic pressure ratings for pipe, tubing, and fittings are listed in Appendix X1. Design and installation considerations are discussed in Appendix X2. An optional performance qualification and an in-plant quality control program are recommended in Appendix X3.

of the standard as published by ASTM is to be considered the official document.
Designation: D2846/D2846M − 19a D2846/D2846M − 24 An American National Standard
Standard Specification for
Chlorinated Poly(Vinyl Chloride) (CPVC) Plastic Hot- and
Cold-Water Distribution Systems
This standard is issued under the fixed designation D2846/D2846M; the number immediately following the designation indicates the
year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last
reapproval. A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the U.S. Department of Defense.
1. Scope*
1.1 This specification covers requirements, test methods, assembly, and methods of marking for chlorinated poly(vinyl chloride)
plastic hot- and cold-water distribution system components made in one standard dimension ratio and intended for water service
up to and including 180 °F (82 °C). These components comprise pipe and tubing, socket-type fittings, street fittings,
plastic-to-metal transition fittings, solvent cements, and adhesives. Requirements and methods of test are included for materials,
workmanship, dimensions and tolerances, hydrostatic sustained pressure strength, and thermocycling resistance. The components
covered by this specification are intended for use in residential and commercial, hot and cold, potable water distribution systems.
1.2 The products covered by this specification are intended for use with the distribution of pressurized 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 1—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.
1.3 The text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notes and
footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each
system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the
two systems may result in non-conformance with the standard.
NOTE 2—Suggested hydrostatic design stresses and hydrostatic pressure ratings for pipe, tubing, and fittings are listed in Appendix X1. Design and
installation considerations are discussed in Appendix X2. An optional performance qualification and an in-plant quality control program are recommended
in Appendix X3.
1.5 The following safety hazards caveat pertains only to the test method portion, Sections 9 and 10, 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, health, and environmental practices and determine the applicability of regulatory
limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
This specification is under the jurisdiction of ASTM Committee F17 on Plastic Piping Systems and is the direct responsibility of Subcommittee F17.61 on Water.

D2846/D2846M − 24
3.1.1 General—Definitions used in this specification are in accordance with Terminology F412, unless otherwise specified. The
abbreviation for chlorinated poly(vinyl chloride) is CPVC. Plastic tubing denotes a particular diameter schedule of plastic pipe in
which the outside diameter of the tubing is equal to the nominal size plus ⁄8 in. (3.18 mm).(3.18 mm).
3.1.2 relation between standard dimension ratio, stress, and internal pressure—the following expression is used to relate standard
dimension ratio, stress, and internal pressure for pipe and tubing:
2S/P 5 R 2 1 (1)
or
2 S/P 5 ~D / t ! 2 1 (2)
where:
S = stress in circumferential or hoop direction, psi (MPa),
P = internal pressure, psi (MPa),
D = average outside diameter, in. (mm),
t = minimum wall thickness, in. (mm), and
R = standard dimension ratio, SDR
3.1.3 standard dimension ratio (SDR)—a selected series of numbers in which the average outside diameter to minimum wall
thickness dimension ratios are constant for all sizes of pipe and tubing in each standard dimension ratio, and which are the ANSI
Z17.1 Preferred Number Series 10 modified by +1. SDR fittings shall by definition be equivalent in minimum socket wall thickness
to the minimum wall thickness of the corresponding SDR and size of pipe or tubing, and the minimum body wall thickness shall
be 125 % of that value.
3.1.4 standard material designation code—the chlorinated poly(vinyl chloride) material designation code shall consist of the
abbreviation CPVC followed by two digits indicating the ASTM type and grade in Arabic numerals. Where necessary, a third and
fourth digit shall be added to indicate the hydrostatic design stress for water at 73 °F [23 °C] 73 °F [23 °C] in units of 100 psi [0.69
MPa].
4. Classification
4.1 Pipe, Tubing, and Fittings—This specification classifies CPVC 4120 pipe, tubing, and fittings by a single standard dimension
ratio which shall be SDR 11, by a maximum continuous use temperature which shall be 180 °F [82 °C] 180 °F [82 °C] and by
nominal pipe or tubing diameters from ⁄4 in. [9.5 mm] through 2 in. [50 mm].[50 mm].
4.2 Transition Fittings—This specification classifies transition fittings intended for use up to and including 180 °F [82 °C] as
CPVC-180 °F on the basis of resistance to failure by thermocycling.
4.3 Solvent Cements and Adhesives—This specification classifies solvent cements and adhesives meeting the requirements
contained herein as CPVC Solvent Cement or CPVC Adhesive.
NOTE 3—This specification does not include requirements for pipe fittings intended to be used to vent combustion gases. UL 1738 is a standard that does
include specific testing and marking requirements for flue gas venting products, including CPVC.
5. Materials
5.1 Basic Materials Description—Chlorinated poly(vinyl chloride) plastics used to make pipe, tubing, and fittings meeting the
requirements of this specification are categorized by two criteria; namely, basic short-term properties, and long-term hydrostatic
strength. Sections 5.1.1 and 5.1.2 respectively define these categories.
5.1.1 Basic Short-Term Properties—This specification covers CPVC 41 pipe, tubing, and fittings made from plastic materials
meeting the mechanical strength, heat resistance, flammability, and chemical resistance requirements for CPVC 23447 in
Specification D1784.

A
All dimensions are in inches and millimetres. (1 in. = 25.4 mm.)
B
The minimum is the lowest wall thickness at any cross section. The maximum permitted wall thickness, at any cross section, is the minimum wall thickness plus the stated
tolerance. All wall tolerances are on the plus side of the minimum requirement.
C
The maximum out-of-roundness applies to the average measured outside diameter.
D 1
For tubing sizes of ⁄2 in. and below, wall thickness minimums are not a function of SDR.
NOTE 4—CPVC 23447 was formerly designated as CPVC Type IV Grade 1, and is herein designated as CPVC 41. This is also used in marking pipe,
tubing, or fittings.
5.1.2 Long-Term Hydrostatic Strength—This specification covers CPVC 41 pipe, tubing, and fittings which are further defined by
hydrostatic design stress as CPVC 4120. Pipe and tubing are so defined on the basis of long-term hydrostatic strength tests and
are made from compounds having an established 180 °F [82 °C] hydrostatic design stress of 500 psi [3.45 MPa] or greater in
accordance with Test Method D2837. Fittings are so defined by hydrostatic sustained pressure tests on fitting assemblies, required
by this specification (see 6.2), based on the hydrostatic strength of the corresponding pipe or tubing.
NOTE 5—No hydrostatic design stress, as such, exists for fittings until such time as long-term hydrostatic strength test methods for fittings are developed.
5.2 The PEX fitting ends of CPVC to PEX transition fittings shall meet the material and dimensional requirements of the
corresponding PEX fitting standard.
5.3 The PERT fitting ends of CPVC to PERT transition fittings shall meet the material and dimensional requirements of the
corresponding PERT fitting standard.
5.4 Rework Material—Clean rework plastic material generated from the manufacturer’s own plastic tube or fitting production may
be used by the same manufacturer provided the pipe, tubing, or fittings meet all the requirements of this specification.
6. Requirements for Pipe, Tubing and Fittings
6.1 Dimensions and Tolerances:
6.1.1 General:
6.1.1.1 Wall Minimums—Table 1 and Table 2 show wall thickness minimums. Calculated SDR 11 fitting wall thicknesses that fall
below 0.102 in. [2.59 mm] 0.102 in. [2.59 mm] for the fitting socket bottom, or 0.128 in. [3.25 mm] 0.128 in. [3.25 mm] for the
fitting body, shall be arbitrarily increased to these values.
6.1.1.2 Interference Fit—The diameters and tolerances in Table 1 and Table 2 provide for socket-type joints having an interference
fit based on the major diameter of pipe and tubing having a degree of out-of-roundness.
6.1.1.3 Out-of-Roundness—The maximum out-of-roundness requirements shown in Table 1 and Table 2 for pipe, tubing, and
fittings apply to the average measured diameter.
NOTE 6—Example: In the 1-in. [25 mm] tubing size, if the measured average tubing diameter was 1.123 in. [28.52 mm], then the extreme measured
diameters due to ovality could be 1.129 in. [28.68 mm] maximum and 1.117 in. [28.37 mm] [28.37 mm] minimum.

log P = −0.097269 log t + 2.619884 (95 % confidence in water)
(2) CPVC tapered socket-ends of CPVC to PEX and CPVC to PERT transition fittings shall meet the dimensional requirements
of Table 2 where applicable.
(3) The PEX fitting end of CPVC to PEX and CPVC to PERT transition fittings shall meet the applicable requirements of the
corresponding ASTM fitting standard. See the following specifications for these requirements: F1960, F1961, F1807, F2080,
F2098, F2159, F2434 and F2735.
6.2 Hydrostatic Sustained Pressure:
6.2.1 General—Pipe, tubing, and fittings (tested as assemblies) shall meet the minimum hydrostatic sustained pressure
requirements of both test conditions shown in Table 5 when tested in accordance with 9.3.
6.2.2 Pipe and Tubing Quality—Test Condition B shall be termed the primary sustained pressure test for pipe and tubing and shall
be used for quality control (see Appendix X3). Test Condition A shall be termed the secondary sustained pressure test for pipe and
tubing and shall be used for periodic performance qualification. Failure to pass either test is cause for rejection.
6.2.3 Fitting Quality—Test Condition A shall be termed the primary sustained pressure test for fittings and shall be used for quality
control (see Appendix X3). Test Condition B shall be termed the secondary sustained pressure test for fittings and shall be used
for periodic performance qualification. Failure to pass either test is cause for rejection.
NOTE 7—Drop weight impact resistance is correlatable with hydrostatic sustained pressure resistance for CPVC 41 components, and may be useful for
predicting compliance with the sustained pressure requirements of Table 5. Such correlations will necessarily differ with the size, wall thickness, and
geometry of individual components. Test Method D2444 using Tup A and Holder A is suggested for nominal diameters of 1 in. [25 mm] and above. For
smaller components, a guided mandrel type of impacter such as the Gardner Impacter equipped with a ⁄2 in. [12.7 mm] radius mandrel is suggested.
Drop impact is not included in this specification directly as a quality requirement because of the wide test scatter normally associated with this test, and
also because of the wide differences in value over the range of sizes and components covered in this specification.
6.3 Thermocycling—Transition fittings (other than metal socket-type transitions for use with adhesives), assembled according to
the manufacturer’s instructions, shall not separate or leak when thermocycled 1000 times between the temperatures of 60 °F and
180 °F [16 °C and 82 °C] in accordance with 9.3.
7. Requirements for Solvent Cement and Adhesive Joints
7.1 CPVC Solvent Cements:
7.1.1 General—CPVC solvent cements, for use in CPVC 41, plastic-to-plastic, socket-type joints using the one-step solvent
cementing procedure (Practice F3328) shall meet the requirements set forth in Specification F493.

NOTE 8—Medium bodied viscosity cement is recommended for CPVC products in this standard requiring the one-step solvent cementing procedure
(Practice F3328). Local or national codes often define color requirements for the solvent cement
7.1.2 Hydrostatic Burst Strength—2-in. [50-mm] CPVC solvent cement joints shall exceed the minimum hydrostatic burst strength
requirements given in Table 6 after a maximum drying interval of 2 h when tested in accordance with 10.1.1. Failure to pass the
burst requirement at either temperature is cause for rejection.
7.1.3 Hydrostatic Sustained Pressure Strength— ⁄2-in. [15-mm] CPVC solvent cement joints shall meet the requirements of 6.2
when tested in accordance with 9.3.
7.1.4 Safe Handling of Solvent Cement—Refer to Practice F402.
7.2 CPVC Adhesives:
7.2.1 General—CPVC adhesives (other than CPVC solvent cement), shall qualify for use in CPVC socket-type joints by a rigorous
simulated use testing program as further defined in 7.2.2 and 7.2.3. CPVC adhesives shall be tested in the largest size joint and
in the exact type of joint for which they are intended; that is, 2-in. [50-mm] plastic-to-metal or 2-in. [50-mm] plastic-to-plastic.
7.2.2 Hydrostatic Sustained Pressure Strength—Socket-type CPVC adhesive joints, made and cured according to the adhesive
manufacturer’s instructions, shall not separate or leak when tested in accordance with 10.2 at the hydrostatic sustained pressure
condition given in Table 7.
7.2.3 Thermocycling—Socket-type CPVC adhesive joints, made and cured according to the adhesive manufacturer’s instructions,
shall not separate or leak when thermocycled 10 000 times between the temperatures of 60 °F and 180 °F [16 °C and 82 °C] in
accordance with 10.2.
8. Workmanship, Finish, and Appearance
8.1 Workmanship—The pipe and fittings shall be homogeneous throughout and free of visible cracks, holes, foreign inclusions,
or other defects. The pipe shall be as uniform as commercially practicable in color, opacity, density, and other physical properties.
9. Test Methods for Pipe, Tubing, and Fittings
9.1 Sampling—A sufficient quantity of pipe, tubing, or fittings, as agreed upon between the purchaser and the seller, shall be
selected at random from each lot or shipment and tested to determine conformance with this specification. In the case of no prior
agreement, random samples selected by the testing laboratory shall be deemed adequate.
9.1.1 Test Specimens—Not less than 50 % of the test specimens required for any pressure test shall have at least a part of the
marking in their central sections. The central section is that portion of pipe which is at least one pipe diameter away from an end
closure.
9.2 Flattening—Flatten three specimens of the pipe, 2 in. [50-mm] long, between parallel plates in a suitable press until the
distance between the plates is 40 % of the outside diameter of the pipe or the walls of the pipe touch, whichever occurs first. The
rate of loading shall be uniform and such that the compression is completed within 5 min. Upon removal of the load, examine the
specimens for evidence of splitting, cracking, or breaking.
9.3 Hydrostatic Sustained Pressure:
9.3.1 Summary of Test Method—This test method describes a pass-fail test for CPVC 41 pipe, tubing, or fittings (tested as
assemblies) subjected to a constant internal hydrostatic pressure for a predetermined period of time. Test conditions are based on
