This British Standard specifies requirements for unsintered polytetrafluoroethylene (PTFE) tapes with a mass per unit area within the range 25 g/m2 to 300 g/m2 and with a thickness in the range 0.05 mm to 0.25 mm.
It specifies requirements for three grades of unsintered PTFE tape, for general or special engineering applications at temperatures between –270 °C and +260 °C. All grades of this tape are suitable for use with most common liquids and gases and in an oxygen-enriched environment.
In addition to the definitive requirements, this standard also requires the items detailed in Clause 3 to be documented. For compliance with this standard, both the definitive requirements and the documented items have to be satisfied.
