24、006, Uncontrolled Copy, (c) BSI EN 60684-3-340 to 342:1994 BSI 12-19993 Introduction This International Standard is one of a series which deals with flexible insulating sleeving for electrical purposes. This series consists of three parts: Part 1: Definitions and general requirements (IEC 684-1); Pa
25、rt 2: Methods of test (IEC 684-2); Part 3: Specification requirements for individual types of sleeving (IEC 684-3). This standard contains three of the sheets comprising part 3, as follows: Sheet 340: Expandable braided polyethylene terephthalate textile sleeving, uncoated, general purpose, thin wal
26、l thickness. Sheet 341: Expandable braided polyethylene terephthalate textile sleeving, uncoated, general purpose, intermediate wall thickness. Sheet 342: Expandable braided polyethylene terephthalate textile sleeving, uncoated, general purpose, thick wall thickness. 1 General 1.1 Scope This Interna
27、tional Standard gives the requirements for sleeving having the property of expanding its bore diameter when compressed longitudinally and thereafter returning to its initial diameter after release of the compressing force. It is constructed of polyethylene terephthalate monofilament yarns suitably p
28、rocessed to provide the mechanical ability to conform in the manner described above. Sleeving of this type is generally available in bore sizes from 6 mm through 63 mm and in three levels of wall thickness (thin, intermediate and thick). It has been found suitable for application up to 130 C. It is
29、normally available in the following colours: Black, white, brown, red, orange, yellow, green, blue, grey and natural. Because of its open construction, this sleeving is normally used to provide air-space insulation. Therefore, no requirement for breakdown voltage is specified in this standard. (Any
30、value for this property should be given in the purchase contract, but a typical value is 1,5 kV/mm of wall thickness, although a linear relationship cannot be assumed.) However, it serves to provide mechanical protection to circuit components such as wires, sleeves and flat cable over which it is ap
31、plied as a containing wrap or harness. 1.2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All normative documents are
32、 subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. IE

If the sleeving is to be supplied with additional properties of mould resistance or fray resistance referred to in 3.2, then the letter “X” shall be added to the end of the desig

For example: IEC 684-3-340-6-red-X 3 Requirements 3.1 Basic requirements for compliance Sleeving shall comply with the requirements of: a) IEC 684-1, and b) Table 1 and Table 2 of this standard. 3.2 Special additional requirements If the sleeving is to be supplied with specific resistance to
37、 mould growth or fraying, it shall also comply with the appropriate requirements of Table 3.
