UL 510A:2017 Component Tapes.
1.1 UL 510A covers adhesive and non-adhesive backed tapes intended for use with finished electro-mechanical products.
1.2 Results obtained provide data with respect to the physical, electrical, flammability, thermal, adhesion and other properties of the tapes under consideration and are intended to provide guidance for tape manufacturers, end-product manufacturers, safety engineers, and other interested parties.
1.3 This standard also covers tapes which have only been subjected to thickness and flammability tests in accordance with Thickness, Section 9 and Flame Test, Section 20, respectively. Tapes subjected only to flammability tests in accordance with Section 20 may employ a conductive backing.
1.4 This standard does not cover adhesive coated polyvinyl chloride (PVC), adhesive coated
polyethylene (PE) and rubber tapes intended for use on joints and splices in wires and cables in
accordance with the National Electrical Code, NFPA 70 at not more than 80°C (176°F) and 600 V. These
types of tapes are covered by the Standard for Polyvinyl, Polyethylene, and Rubber Insulating Tape, UL
510.
2 Units of Measurement
2.1 Values stated without parentheses are the requirement in SI units, unless otherwise noted. Values in parentheses are explanatory or approximate information.
3 Referenced Publications
3.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be
interpreted as referring to the latest edition of that code or standard.
4 Use of Tapes
4.1 The safety of electrical equipment often depends upon the correct selection of tapes, design, as well as the assembly, mounting, and relative positions of these parts.
4.2 The properties needed by individual applications are defined by the function or functions of the tape.
A tape used as interwinding insulation in a transformer, for example, must ordinarily be designed to
withstand electrical stress at elevated use temperatures. Accordingly, a tape known to have suitable
thermal endurance and substantial dielectric strength would normally be used although a material of lower
dielectric strength used in multiple layers may also be satisfactory.
4.3 End products may employ many tapes that usually have divergent properties. The ability to match the demands of the application with the attributes of a tape as well as the ability to compare the properties of one tape with those of another can lead to the selection of an acceptable tape.UL 510A pdf download.
