20、 sleeving for electrical purposes. The series consists of three parts: Part 1: Definitions and general requirements (IEC 60684-1); Part 2: 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
21、, as follows: Sheet 420: Polyethylene terephthalate textile with acrylic based coating: high breakdown voltage Sheet 421: Polyethylene terephthalate textile with acrylic based coating: medium break- down voltage Sheet 422: Polyethylene terephthalate textile with acrylic based coating: low breakdown
22、voltage Page3 EN606843420TO422FLEXIBLE INSULATING SLEEVING Part 3: Specification for individual types of sleeving Sheets 420 to 422: Polyethylene terephthalate textile sleeving with acrylic based coating 1 Scope This International Standard gives the requirements for three types of sleeving construct
23、ed from polyethylene terephthalate yarns using either braided or knitted construction, with a continuous acrylic based coating and differentiated by their breakdown voltage: high breakdown voltage (sheet 420), medium breakdown voltage (sheet 421) and low breakdown voltage (sheet 422). The sleeving i
24、s normally available with internal diameters between 0,5 mm and 25 mm and is normally supplied in the following colours: black, yellow, 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 com
25、ply with this standard if they comply with the property requirements listed in tables 2 and 4. Experience of product performance 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 refe
