19、3-145 to 147 IEC:2001 3 INTRODUCTION This International Standard is one of a series which deals with flexible insulating 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: Sp
20、ecification requirements for individual types of sleeving (IEC 60684-3). This standard contains three of the sheets comprising part 3 as follows: Sheet 145: Extruded PTFE sleeving Thin wall Sheet 146: Extruded PTFE sleeving Standard wall Sheet 147: Extruded PTFE sleeving Thick wall Page3 EN606843145
21、to147 BSI21December200160684-3-145 to 147 IEC:2001 4 FLEXIBLE INSULATING SLEEVING Part 3: Specifications for individual types of sleeving Sheets 145 to 147: Extruded PTFE sleeving 1 Scope These sheets of IEC 60684-3 give the requirements for three types of non-heat-shrinkable sleeving, extruded from
22、 PTFE. Sleeving of this type is normally available with internal diameters up to 8,53 mm and in a range of wall thicknesses between 0,15 mm and 0,51 mm. This specification covers three levels of wall thickness: “thin wall”, “standard wall” and “thick wall” related to nominal internal diameter and wi
23、th corresponding differences in requirements for breakdown voltage. Experience of product performance indicates that PTFE sleeving may be suitable for inclusion in systems for operation at temperatures up to 250 C. These sleevings are normally available in the following opaque colours: black, brown,
24、 red, orange, yellow, green, blue, violet, grey, white, pink and turquoise. It is also available as non- coloured. 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
25、 the other property requirements listed in tables 1 and 2. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC 60684. For dated references, subsequent amendments to, or revisions of, any of these
26、 publications do not apply.
