Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
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. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 13000-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic
materials.
This second edition cancels and replaces the first edition (ISO 13000-2:1997), which has been technically
revised.
ISO 13000 consists of the following parts, under the general title Plastics — Polytetrafluoroethylene (PTFE)
semi-finished products:

3 Terms and definitions
For the purposes of this part of ISO 13000, the terms and definitions given in ISO 472 and ISO 13000-1 apply.
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. Sampling shall be statistically
adequate to satisfy the requirements of the test method concerned.
5 Preparation of test specimens
The specimens used for testing shall be taken directly from or shall 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 applicable, ISO standards shall be followed for the preparation of
test specimens. In some instances, special procedures are required that are described either in the general
discussion or in the method.
6 Testing of semi-finished PTFE products
6.1 General
Properties required for specification purposes shall be determined in accordance with the International
Standards referenced in this part of ISO 13000 or the procedures given in this part of ISO 13000. For the
determination of density, tensile properties, hardness and electrical properties, condition the test specimens at
23 °C ± 2 °C for a period of at least 4 h prior to test. The other tests require no conditioning.
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 ISO 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 to 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 moulded basic shapes, rods or tubes conforming to 6.3.1.2 are likely to give
results similar to those obtained with 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 result 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 of reporting test results. The micro-tensile test specimen (see 6.3.1.3) 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, and so that the
shape is as shown in Figure 1. The value of the larger diameter (D) shall be 7 mm ± 0,5 mm, 10 mm ± 0,5 mm
or 20 mm ± 0,5 mm.
