DIN EN ISO 13000-1:2006-02

This part of the standard specifies requirements for processed unfilled polytetrafluorethylene (PTFE) products which may occur in several forms. The PTFE used to make the semi-finished product is described in ISO 12086-1and, 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 colourant 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 processed (type P) or dimensionally stabilized (type S) and also may have specified electrical properties of other properties when are required for an application.
