Standard Specification for Extruded and Compression Molded Shapes Made from Poly(Vinylidene Fluoride) (PVDF)

ABSTRACT
This specification covers the requirements and test methods for the material, dimensions, and workmanship, and the properties of extruded sheet, rod and tubular bar manufactured from Poly(Vinylidene Fluoride) (PVDF). The type of PVDF shape product may be categorized by type, grade and class depending on resin and filler compositions. Each type of shape may be categorized into one of several grades as follows: Grade 1 - unmodified virgin-extruded or compression molded product made using only 100 % virgin PVDF material; Grade 2 - general purpose-extruded or compression molded product made using up to 20 % PVDF regrind developed during internal processing steps may be used; and Grade 3 - recycled-extruded or compression molded product made using up to 100 % recycled PVDF resin. The type, class and grade is further differentiated based on dimensional stability (elevated temperature excursion test), and dimensional requirements. Materials shall be tested and the individual grades shall conform to specified values of the physical properties such as tensile strength, tensile elongation, tensile modulus, dimensional stability, flexural modulus, and Izod impact; and dimensional properties such as diameter tolerance, roundness, camber, thickness tolerance, length camber, and width bow.
SCOPE
1.1 This specification covers the requirements and test methods for the material, dimensions, and workmanship, and the properties of extruded sheet, rod and tubular bar manufactured from PVDF.  
1.2 The properties included in this specification are those required for the compositions covered. Requirements necessary to identify particular characteristics important to specialized applications are described by using the classification system given in Section 4.  
1.3 The values stated in English units are to be regarded as the standard in all property and dimensional tables. For reference purposes, SI units are also included in Tables X and S-PVDF only.  
1.4 The following safety hazards caveat pertains only to the test method or test methods described in 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. ISO 12086-1 and ISO 12086-2 have pertinent information.  
1.5 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.

4.5 Callout Designation—A one-line system shall be used to specify PVDF materials covered by this specification. The system
uses predefined 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 unfilled virgin PVDF:
CELL CALLOUT: S-PVDF0111
where:
S-PVDF01 = product made from PVDF in accordance with Table S-PVDF,
1 = unfilled class, and
1 = unmodified virgin grade product.
4.5.1.2 Example 2—Product made from 10 % carbon fiber blended with unmodified virgin PVDF resin:
CELL CALLOUT: S-PVDF0100C10X3454430
where:
S-PVDF0100 = product made from PVDF in accordance with Table S-PVDF, unspecified,
C10 = 10 % carbon fiber,
X = Table X properties,
3 = tensile strength (10,000 psi),
4 = elongation at break (10 %),
5 = tensile modulus (500,000 psi),
4 = dimensional stability (0.4 %),
4 = flexural modulus (550,000 psi),
3 = Izod impact (1.0 ft-lb/in of notch), and
0 = unspecified.
4.5.2 These two examples illustrate how an on-line, alphanumeric sequence identifies the product composition, commercial
parameters and physical characteristics of extruded or compression molded 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 must be preceded by a comma. Special tolerances must be noted at the time of order and are
inserted after the grade in parenthesis and preceded by a comma.
5. Property Requirements
5.1 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 must be specified at the time of order. Physical properties for products
not yet included in Table S-PVDF shall be specified using Table X for extruded or compression molded products.
D6713 − 21
6. Dimensional Requirements
6.1 The type, class and grade is differentiated based on dimensional stability (elevated temperature excursion test), Table S-PVDF
and dimensional requirements, Tables A and B. Products shall be produced within commercial tolerances and with the lowest stress
levels for machined parts as delineated in Tables A and B for extruded and compression molded products.
6.2 Tubular bar dimensions shall be supplied in the unfinished condition, unless otherwise specified at time of order sufficient to
finish to the nominal dimension ordered.
6.3 The maximum allowable camber or bow, or both, shall be within the limits referenced in Tables A and B.
7. Workmanship, Finish, and Appearance
7.1 Appearance—The color of products shall be as published by the shapes manufacturer. They shall be uniform in color
throughout the thickness. Specific colors and color-matching only agreed to by order. It is possible for physical properties to be
affected by colors.
7.2 Finish—All products shall be free of blisters, wrinkles, cracks, gouges and defects that restrict commercial use of the product.
A special surface finish shall be supplied only when specified in the purchase order or contact.
7.3 Defects—All products shall be free of voids, dirt, foreign material and embedded particles exceeding ⁄32 in. maximum
diameter as defined in 7.3.1.
7.3.1 The criteria for determining internal cleanliness shall be external visual inspection. A maximum number of two internal
defects per square foot of sheet and one foot length of rod and tubular bar shall be allowed. Clusters of defects less than ⁄32 in.
diameter are to be counted as a single defect.
8. Sampling
8.1 Sampling shall be statistically adequate to satisfy the requirements of this specification as applicable.
8.2 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.
9. Number of Tests
9.1 Routine lot inspection shall consist of all criteria specified in the applicable product tables.
9.2 The criteria listed in these product tables and definitions are sufficient to establish conformity of the sheet, rod or tubular bars
to this specification. When the number of test specimens is not stat
