This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

INTRODUCTION
This specification is intended to be a means of calling out mechanical grade plastic product used in
the fabrication of end items or parts.
1. Scope*
1.1 This specification covers requirements and test methods for the material, dimensions, and workmanship, and the properties of
extruded shapes of rods and bars made from poly(vinyl chloride) (PVC), and chlorinated poly(vinyl chloride) (CPVC).
1.2 The properties included in this specification are those required for the compositions covered. Use the classification system
given in Section 4 to describe requirements necessary to identify particular characteristics important to specialized applications.
1.3 This specification allows for the use of regrind and recycled plastics providing products produced from regrind or recycled
PVC material can be shown to meet the requirements of this standard with regard to material classification, physical performance,
dimensions and workmanship; and the regrind or recycled plastics used have not been subjected to severe environments in post
consumer applications (such as chemical service) which could adversely affect the end products performance when subjected to
machining or critical applications or both.
1.4 The values are stated in inch-pound units and are regarded as the standard in all property and dimensional tables. For reference
purposes, SI units are also included in Table 1 only.
1.5 The following safety hazards caveat pertains only to the test method portions section 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.
NOTE 1—There is no known ISO equivalent to this standard.
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 D20 on Plastics and is the direct responsibility of Subcommittee D20.15 on Thermoplastic Materials

4.4.3 To facilitate the incorporation of future or special materials not covered by Tables S-PVC-I and S-PVC-II, the “as specified”
category (00) for type, class and grade is shown in the applicable table with the basic properties to be obtained from Table 1 as
they apply.
4.5 Callout Designation—A one-line system shall be used to specify poly(vinyl chloride), or chlorinated poly(vinyl chloride)
materials covered by this specification. The system uses pre-defined cells to refer to specific aspects of this specification as
illustrated below:
4.5.1 Examples:
4.5.1.1 Example 1—Product made from general purpose poly(vinyl chloride):
CELL CALLOUT: S-PVC0111
S-PVC01 = Product made from PVC in accordance with Table
S-PVC-I and Table S-PVC-II
1 = Unfilled class
1 = General purpose grade product
4.5.1.2 Example 2—Product made from general purpose chlorinated poly(vinyl chloride):
CELL CALLOUT: S-CPVC0211
S-PVC02 = Product made from CPVC in accordance with
Tables S-PVC-I and S-PVC-II
1 = Unfilled class
1 = General purpose grade product
4.5.2 These two examples illustrate how a one-line, alpha-numeric sequence can identify the product composition, commercial
parameters and physical characteristics of extruded product. A space must be used as a separator between the specification number
and the type designation. No separators are needed between type, class, and grade. When special notes are to be included, such
information shall be preceded by a comma. Special tolerances must be noted at time of order and are inserted after the grade in
parenthesis and preceded by a comma.
4.5.2.1 The material used in the manufacture of PVC and CPVC shapes intended for contact with or the transport of potable water,
or both, must be evaluated and certified as safe for this purpose by a testing agency acceptable to the local health authority. The
evaluation shall be in accordance with the requirements for chemical extraction, taste, and odor, that are no less restrictive than
those included in the National Sanitation Foundation (NSF) Standard 61.
5. Ordering Information
5.1 All shapes covered by this specification shall be ordered using the proper callout designation (see 4.5).
6. Physical Property Requirements
6.1 The physical property values listed within this specification’s tables are to be considered minimum specification values. Any
requirement for specific test data for a given production lot shall be specified at the time of order. Use Table 1 to specify physical
properties for extruded products not yet included in Table S-PVC-I or S-PVC-II.
7. Dimensional Requirements
7.1 The type, class, and grade is differentiated based on dimensional stability (elevated temperature excursion test) as indicated
in Table S-PVC-II.
7.2 Products shall be produced within the commercial tolerances and with the lowest stress levels for machined parts as delineated
in Table A.
7.3 Tubular bar dimensions shall be supplied in the unfinished condition, unless otherwise specified at time of order, sufficient to
finish to the nominal dimensions ordered.
D6263 − 23
7.4 The maximum allowable camber at final inspection at the factory shall be within the limits referenced in Table A.
8. Workmanship, Finish, and Appearance
8.1 Appearance—The resin material color for poly(vinyl chloride) shall be dark gray. The resin material color for chlorinated
poly(vinyl chloride) shall be light gray. All shapes shall be uniform in color throughout the thickness. Specific colors and color
matching only as agreed to by order.
8.1.1 It is possible that physical properties will be affected by other colors. Regardless of color, minimum properties of 4.4 must
be met.
8.2 Finish—All products shall be free of blisters, wrinkles, cracks, gouges and defects that restrict commercial use of the product.
Special surface finish shall be supplied only when specified in the purchase order or contract.
8.3 Defects—All products shall be free of visual voids, dirt, foreign material and embedded particles exceeding 0.040 in. (1 mm)
maximum diameter as defined in 8.3.1
8.3.1 The criteria for determining the cleanliness shall be external visual inspection. A maximum number of two defects per one
foot length of rod and tubular bar are allowed. Clusters of defects less than 0.040 in. (1 mm) diameter are to be counted as a single
defect.
8.4 Extrusion Quality—Products shall not flake or disintegrate when tested in accordance with the test method for degree of fusion
as defined in 12.6.
9. Sampling
9.1 Sampling shall be statistically adequate to satisfy the requirements of this specification as applicable (see ANSI Z1.4-1993).
9.2 For purposes of sampling, an inspection lot for examination and tests shall consist of all material of the same type, class, grade
and nominal size submitted for inspection at one time.
10. Number of Tests
10.1 Routine lot inspection shall consist of all the criteria specified in the applicable product tables.
10.2 The criteria listed in these product tables and definitions are sufficient to establish conformity of the shape to this
specification. When the number of test specimens is not stated in the test method, it is acceptable to make a single determination.
If more than single determinations and separate portions of the same sample are made, the results shall be averaged. The final
