ABSTRACT
This specification covers requirements and methods of test for the material, dimensions, and workmanship, and the properties of extruded, compression molded, and injection molded PAEK sheet, plate, rod, and tubular bar manufactured from PAEK. The type of PAEK extruded, compression molded, and injection molded product may be categorized by type, grade and class depending on resin and filler compositions. Every type of PAEK shape may be categorized into one of several grades as follows: Grade 1 (general purpose) which is extruded, compression molded or injection molded product made using only 100% virgin PAEK resin and Grade 2 (recycle grade) which is extruded, compression molded or injection molded product made using any amount up to 100% of recycled thermoplastic PAEK. The type, class and grade is further differentiated based on dimensional stability. Different tests shall be conducted in order to determine the following properties of PAEK: tensile stress at break, elongation at break, tensile modulus, dimensional stability, lengthwise camber and widthwise bow, squareness, flexural modulus, and Izod impact.
SCOPE
1.1 This specification covers requirements for the PAEK materials used and the requirements and methods of test for the dimensions, workmanship, and the properties of extruded, compression molded, and injection molded PAEK sheet, plate, rod, and tubular bar manufactured from PAEK. PAEK is a family of thermoplastic materials that differ in properties (see Section 3).  
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 This specification allows the use of key clad plastics (see Section 4).

4.5 Callout Designation—A one-line system shall be used to specify PAEK materialsshapes covered by this specification. The
system uses predefined cells to refer to specific aspects of this specification, as illustrated below:
4.5.1 Description:
4.5.1.1 Example 1—Extruded natural PAEK extruded rod:rod from PEEK:
D6262 − 23
CELL CALLOUT: S-PAEK0111
S-PAEK01 = Product made from PAEK resin in accordance with
Table S-PAEK
S-PAEK01 = Product made from PAEK resin as called in the
material designation in Table S-PAEK and meeting
shape requirements in Table S-PAEK
1 = Unfilled class
1 = General purpose grade product
4.5.1.2 Example 2—Compression molded natural PAEK plate.plate from PEEK.
CELL CALLOUT: S-PAEK0211
S-PAEK02 = Product made from PAEK in accordance with Table
S-PAEK
S-PAEK02 = Product made from PAEK resin as called in the material
designation in Table S-PAEK and meeting stock shape
requirements in accordance with Table S-PAEK
1 = Unfilled class
1 = General purpose grade product
4.5.2 The two examples illustrate how a one-line, alpha-numericalphanumeric 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 should 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.
5. Physical 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 of PAEK shape should be specified at the time of order. Physical
properties for products not yet included in Table S-PAEK shall be specified using Table 1 for extruded, compression molded, and
injection molded products.
6. Dimensional Requirements
6.1 The type, class, and grade is further differentiated based on dimensional stability (elevated temperature excursion test), Table
S-PAEK, 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 products. The manner in which the tolerances
are obtained is not relevant.
6.2 Tubular bar and compression molded 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 as agreed to by order. Physical properties may 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.
Special surface finish shall be supplied only when specified in the purchase order or contract.
7.3 Defects—All products shall be free of voids, dirt, foreign material and embedded particles exceeding ⁄32 in. (0.8 mm)
maximum diameter as defined below.
7.3.1 The criteria for determining the internal cleanliness shall be external visual inspection. A maximum number of two internal
D6262 − 23
defects per square foot of plate/sheet and 1-ft (0.3-m) length of rod and tubular bar is allowed. Clusters of defects less than ⁄32 in.
(0.8 mm) diameter are to be counted as a single defect.
8. Sampling
8.1 The materials shall be sampled in accordance with a sampling procedure statistically adequate to satisfy the requirements of
12.1. A lot shall be considered as a unit of manufacture defined as a production run.
9. Number of Tests
9.1 Routine lot inspection shall consist of all the 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, plate, rod or tubular
bars to this specification. When the number of test specimens is not stated in the test method, a single determination shall be made.
If more than single determinations and separate portions of the same sample are made, the results shall be averaged. The final result
shall conform to the requirements prescribed in this specification.
10. Test Conditions
10.1 Conditioning of Specimens—The specification values and dimensions are based on conditioning techniques outlined in
Procedure A of Practice D618.
10.2 Standard Temperature—The tests shall be conducted at the standard laboratory temperature of 73.4 6 3.6°F (23 6 2°C) and
50 6 10 % RH.
11. Test Methods
11.1 Tensile stress at break, elongation at break, and tensile modulus (tangent) in accordance with Test Method D638, at the rate
of 0.2 in. (5 mm)/min.
11.1.1 All plate and sheet specimens are in accordance with Type I of Test Method D638. Testing of specimens taken in the
machine flow direction is sufficient.
11.1.2 All rod specimens are in accordance with Type I of Test Method D638.
11.1.3 All tubular bar specimens are in accordance with Type I of Test Method D638.
11.2 Dimensional Stability:
11.2.1 Specimen Preparation (a Minimum of Three Test Samples Required):
11.2.1.1 Rods and Tubular Bar—Prepare each specimen by cutting a 1.5 in. (38 mm) long slice from the shape to be tested. The
slice shall then be machined, using a coolant and good machining practices to a length of 1.000 6 0.005 in. (25 6 0.13 mm). Each
end of the specimen shall have a machined surface.
11.2.1.2 Plate and Sheer—The test is not applicable to sheet under ⁄16 in. (4.8 mm) thick. Each specimen shall consist of a 2 in.
(51 mm) diameter disc machined from the flat (diameter shall equal test specimen thickness with a minimum of 2.0 in. (51 mm).
Use the same care in the machining as described above. The thickness of the specimen shall be that of the original flat from which
it was cut, no machining being done on the top or bottom faces.
11.2.2 Testing Procedure—Place the specimen in an oil bath consisting of polyalkylene glycol or an air circulating oven and heated
to the applicable temperature for PAEK type as noted below. Measure the outside diameter and thickness or length of th
