20、Standard without any modification. Page 3 EN 60684-3-420 TO 422 INTRODUCTION This International Standard is one of a series which deals with flexible insulating sleeving for electrica I purposes. The series consists of three parts: Part 1: Definitions and general requirements (IEC 60684-1); Part 2:
21、Methods of test (IEC 60684-2); Part 3: Specification for individual types of sleeving (IEC 60684-3) This standard contains three of the sheets comprising Part 3, as follows: Sheet 420: Sheet 421: Sheet 422: Polyethylene terephthalate textile with acrylic based coating: high breakdown voltage Polyeth
22、ylene terephthalate textile with acrylic based coating: medium break- down voltage Polyethylene terephthalate textile with acrylic based coating: low breakdown voltage Page 4 EN 60684-3-420 TO 422 FLEXIBLE INSULATING SLEEVING - Part 3: Specification for individual types of sleeving - Sheets 420 to 4
23、22: Polyethylene terephthalate textile sleeving with acrylic based coating 1 Scope This International Standard gives the requirements for three types of sleeving constructed from polyethylene terephthalate yarns using either braided or knitted construction, with a continuous acrylic based coating an
24、d differentiated by their breakdown voltage: high breakdown voltage (sheet 420), medium breakdown voltage (sheet 421) and low breakdown voltage (sheet 422). The sleeving is normally available with internal diameters between 0,5 mm and 25 mm and is normally supplied in the following colours: black, y
25、ellow, brown, blue and red. Sizes or colours other than those specifically 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 property requirements listed in tables 2 and 4. Experience of product performance
26、indicates that sleeving of the types specified in these sheets may be suitable for operation at 130 “C or in some applications at temperatures up to 155 “C. 2 Normative references The following referenced documents are indispensable for the application of this document.
