Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 13000-2 was prepared by Technical Committee
ISOTTC 61, Plastics, Subcommittee SC 9, Thermoplastic materials.
IS0 13000 consists of the following parts, under the general title Plastics -
Polytetrafluoroethylene (PTFE) semi-finished products:
Par? I: Requirements and designation
Par? 2: Preparation of test specimens and determination of properties
Annex A of this part of IS0 13000 is for information only.

4. Sampling
Details of procedures for sampling semi-finished products depend to a large extent on
the physical shape of the particular material. Whenever feasible, the materials shall
be sampled in accordance with IS0 842. Adequate statistical sampling shall be
considered an acceptable alternative.
5. Preparation of test specimens
The specimen used for testing shall be taken directly from or be machined from the
semi-finished product without other treatment. Thus, conversion of a semi-finished
product into a test specimen by any moulding procedure is not permitted. Where
In

Testing of semi-finished PTFE products

6.1 General
Properties required for specification shall be determined according to the
International Standards as referenced in this part of IS0 13000 or the procedures in
this part of IS0 13000. For the determination of density, tensile properties, hardness,

---------------------- Page: 12 ----------------------

and electrical properties, condition the test specimens at 23 * 2 “C for a period of at
least 4 hours prior to test. The other tests require no conditioning.
Informative annex A provides a list of other standards relating to testing semi-
finished products of PTFE.
6.2 Linear dimensions
These shall be determined by the procedures provided in IS0 1923 for cellular
plastics.
6.3 Tensile properties
6.3.1 Tensile specimens
6.3.1.1 General
The appropriate type of test specimen shall be chosen from those given in 6.3.1.2
through 6.3.1.5. At least three test specimens shall be prepared from the sample and
three specimens shall be tested.
NOTE&--Test specimens prepared from the moulded basic shapes, rod, or tube
and conforming to 6.3.1.2 are likely to give similar results to test specimens
prepared from the same product but conforming to 6.3.1.3.
When testing extruded products, the test specimens shall be cut parallel to the axis of
extrusion so that, as far as possible, each test specimen represents a different section
along the axis and a different area of the cross section.
When testing skived tape, skived sheet, or skived film, the test specimens shall be cut
perpendicular to the direction in which the pressure was applied when moulding the
billet from which the product was skived. If this direction is not known, two sets of
test specimens shall be prepared and tested, the test specimens in one set being cut at
90° to those in the other set and the mean results shall be calculated from the higher
set of values (indicating, typically, the direction perpendicular to the axis of applied
pressure). This procedure ensures a uniform way to report results from the testing.
The micro tensile test specimen is used most commonly for PTFE products.
6.3.1.2 Turned dumb-bell test specimens
The test specimens shall be turned so that their dimensions are in the ratios given in
figure 1, with the shape shown in Figure 1. The value of the larger diameter (D) shall
be 7 t 0,5 mm, 10 t 0,5 mm, or 20 t 0,5 mm.

Figure 1 - Turned dumb-bell specimen for tensile testing
6.3.1.3 Micro tensile die (Small punched dumb-bell) test specimens
The sample shall be machined to produce a sheet or disc of thickness 1,5 to 2,5 mm, or
turned to produce a rectangular sectioned ring which can be cut and flattened to give
such a sheet.
Test specimens conforming to the shape shown in Figure 2 and the dimensions given
in table 1 for the micro tensile die shall be punched from sheet or disc using a single
stroke press and the appropriate knife-edged die. In any one test specimen, the
thickness of the narrow parallel-sided portion shall nowhere deviate by more than two
percent from the mean. The sheet shall be supported, while the test specimens are
punched from it, on a slightly yielding material having a smooth surface (e. g. leather,
rubber, or high quality cardboard) on a flat rigid base. The cutting edge of the die
shall be sharp and free from notches or other visual defects. In the case of thin sheet
or skived tape of thickness from 0,125 mm to 3,0 mm, the test specimens shall be
punched from the material ‘as received ’.
