ISO/TC 61/SC 9/WG 22 - PTFE raw materials and products

ISO 20568-1:2017 establishes a system of designation for fluoropolymer materials, which may be used as the basis for specifications. The various types of fluoropolymer are differentiated from each other by a classification system based on appropriate levels of the designatory properties and on information about the intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.

ISO 20568-2:2017 describes the preparation of test specimens and provides test methods to define characteristics of thermoplastic fluoropolymer resins. Results from the testing can be used as the basis for designation, material specifications or both.

ISO 13000-2:2005 specifies the preparation of test specimens and gives the test methods applicable to semi-finished products of polytetrafluoroethylene (PTFE).

ISO 13000-1:2005 specifies the requirements 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 12086-1 and, as provided in ISO 12086-1, 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 four 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.

ISO 12086-2:2006 describes the preparation of test specimens and provides test methods to define characteristics of thermoplastic fluoropolymer resins. Results from the testing may be used as the basis for designation, material specifications or both.

ISO 12086-1:2006 establishes a system of designation for fluoropolymer materials that may be used as the basis for specifications. It covers the homopolymers and various copolymers of fluoromonomers used as dispersions and for moulding, extrusion and other specialized applications.

Describes the preparation of test specimens and provides test methods to determine characteristics of thermoplastic fluoropolymer resins. Results from the testing may be used as the basis for designation, material specifications, or both. Specifies the conditions of test for the determination.

Establishes a system of designation for fluoropolymer materials that may be used as the basis for specifications. Covers the homopolymers and various copolymers of fluoromonomers used as dispersions as well as for moulding and extrusion materials. Describes the designation system and provides codes and tables of values for the designatory properties.
