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 13000-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9,

Thermoplastic materials.

This third edition cancels and replaces the second edition (ISO 13000-1: 2005), which has been

technically revised.

ISO 13000 consists of the following parts, under the general title Plastics — Polytetrafluoroethylene

(PTFE) semi-finished products:
— Part 1: Requirements and designation
— Part 2: Preparation of test specimens and determination of properties

Plastics — Polytetrafluoroethylene (PTFE) semi-finished
products —
Part 1:
Requirements and designation
1 Scope

This part of ISO 13000 specifies the requirements and establishes a system of designation for processed

unfilled polytetrafluoroethylene (PTFE) products, which may occur in several forms. The PTFE used

to make the semi-finished product is described in ISO 20568-1 and, as provided in ISO 20568-1, may

contain up to 1 % of a comonomer. The PTFE used to make the semi-finished product may be virgin,

reprocessed or recycled resin. The addition of up to 1,5 % by mass of pigment or colorant is permitted.

This part of ISO 13000 allows for five grades based on tensile strength and elongation at break. The

semi-finished products can be as-processed (type P) or dimensionally stabilized (type S) and may also

have specified electrical properties or other properties when they are required for an application.

NOTE References to other standards for semi-finished products made from polytetrafluoroethylene are

listed in Annex A for information.

4.1  General

After considering the specific shape, dimensions and dimensional tolerances, the primary basis for

designating a semi-finished product of PTFE is the tensile strength and percentage elongation at

break of the product. Tests to determine the values for designation shall be run in accordance with

the methods in ISO 13000-2. The semi-finished product is identified as “type P” for as-processed or

“type S” for stabilized and also may be designated as “type E” with specified electrical properties when
