1.1 This specification covers glass fabric impregnated, coated, and sintered on both sides with PTFE to a nominal thickness of
0.318 mm (0.015 in.) or less.
1.2 The PTFE-coated glass fabric is for electrical, chemical, and mechanical uses.
1.3 The PTFE-coated glass fabric of this specification does not pertain to structural fabric, single-sided PTFE coatings, or materials used for laminates.
1.4 The values stated in SI units as detailed in IEEE/ASTM SI-10. NOTE 1—There is no ISO standard that covers information included in this specification. The dielectric test is mentioned in ISO 12086-2 and ISO 13000–1 and 2.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
