The series consists of three parts: Part 1: Definitions and general requirements (IEC 60684-1); Part 2: Methods of te
19、st (IEC 60684-2); Part 3: Specifications for individual types of sleeving (IEC 60684-3). This standard is one of the sheets comprising Part 3.

20、 Specifications for individual types of sleeving Sheet 320: Polyethylene terephthalate textile sleeving, lightly impregnated 1 Scope This International Standard gives the requirements for sleeving constructed from polyethylene terephthalate yarn, lightly impregnated with resin to provide mechanical
21、stability. This sleeving has been found suitable for use at temperatures up to 130 C. It is normally available in internal diameters between 1 mm and 12 mm and is normally supplied in the following colours: natural, blue, red, yellow, black, green and brown. Sizes or colours other than those specifi
22、cally listed in this standard may be available as custom items. These items shall be considered to comply with this standard if they comply with the other property requirements listed in tables 2 and 3. Materials which conform to this specification meet established levels of performance. However, th
23、e selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. 2 Normative references The following referenced documents are indispensable for the application
24、of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
