21、54-1:1994 BSI 12-1999 3 Introduction This part of IEC454 is one of a series which deals with the characteristics of pressure-sensitive adhesive tapes for electrical purposes. The series consists of three parts: Part1: General requirements (IEC454-1); Part2: Methods of test (IEC454-2); Part3: Specifi

22、cations for individual materials (IEC454-3). 1 Scope This part of IEC454 gives general requirements for pressure-sensitive adhesive tapes for electrical purposes. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions

23、of this part of IEC454. At the time of publication, the editions indicated were valid. All normative documents are subject to revision, and parties to agreements based on this part of IEC454 are encouraged to investigate the possibility of applying the most recent editions of the normative documents

24、 indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. IEC304:1982, Standard colours for insulation for low-frequency cables and wires. ISO472:1988, Plastics Vocabulary. 3 Definition For the purpose of this International Standard, the following defini

25、tion applies: 3.1 pressure-sensitive adhesive tapes category of tapes coated on one or both faces with a pressure-sensitive adhesive which is permanently tacky at room temperature. They require no activation by water, solvent or heat to adhere to a variety of dissimilar surfaces upon contact, using

26、only light pressure 4 Classification and designation The tape shall be classified by: a) form and nature of backing (base) material; b) temperature index of pressure-sensitive adhesive tape(4.1); c) nature of adhesive(4.2); d) the addition of “2” at the end of the designation denotes that the tape i

27、s coated with adhesive on both sides. Particular types of tape may be designated by using the code letters for the form and nature of backing material given in Table 1, followed by the figures for temperature index and code letters for the adhesive, as indicated in4.2. Examples of designation: Code

29、e tape used in the classification shall be that value given in the Part3 sheet. NOTEThe temperature index, while giving guidance of the thermal ageing behaviour of the material, should not be identified with the maximum admissible service temperature of this material in an insulation system. 4.2 Adh

30、esive The designation of the adhesive is given in Table 2. 5 Appearance Tape may be transparent, translucent or opaque and be supplied coloured or not coloured. For tapes that are coloured, the colours shall be as near as possible a match for the colours in IEC304. 6 Freedom from defects Each roll s

31、hall be reasonably free from telescoping and distortion. When unwound, the tape shall show negligible transfer of adhesive to the backing of the underlying turn, tearing of the backing (base), fraying or tearing of threads. 7 Dimensions 7.1 Core diameter The preferred internal diameters of the cores

32、 on which the tape is rolled are approximately26mm and76mm. 7.2 Width The preferred widths of the tape are6mm,9mm,12mm,15mm,19mm,22mm,25mm,30mm,38mm or50mm. Alternative widths may be used based on agreement between purchaser and supplier. 7.2.1 Tolerance on width The width shall not deviate by more

33、than1mm for widths up to and including19mm and 1,5mm for greater widths. Closer tolerances than those stated can be specified in the individual specifications sheets, if needed. 7.3 Length The preferred lengths of tape on a roll are5m,10m,16m,20m,25m,33m,50m,55m,66m and82m. The actual length shall b

34、e not less than the stated length. Other lengths may be used based on agreement between purchaser and supplier. 7.4 Thickness Thicknesses are specified in the individual specification sheets.

37、eet of part3 or the declared expiry date given by the supplier. 9 Packing The individual rolls of tape shall be packed in such a manner that: a) they are reasonably protected from moisture, dust and sunlight; b) they can easily be separated; c) they are reasonably protected from damage during normal

38、 transit conditions. 10 Marking Each roll shall have the manufacturers or suppliers identification clearly marked on the core of the roll or on the roll label. Each transit pack (carton) shall have the following information clearly and indelibly marked on it: a) the number of this standard; b) the d

39、esignation of the tape, in accordance with clause4; c) the appearance of the tape, according to clause5; d) the nominal width of the tape; e) the length of the tape on each roll; f) the nominal thickness of the tape; g) the number of rolls in the transit pack; h) “This side up” or a similar indicati

Polymer type Characteristics R=Rubber Tp=Thermoplastic a A=Acrylic Tc=Thermosetting b S=Silicone Tx=Crosslinked c O=Other a thermoplastic (adjective): Capable of being repeatedly

44、 softened by heating and hardened by cooling through a temperature range characteristic of the plastic and, in the softened state, of being repeatedly shaped by flow into articles by moulding, extrusion or forming (ISO472). b thermosetting: Capable of being changed into a substantially infusible and

45、 insoluble product when cured by heat or by other means such as radiation, catalysts, etc. (ISO472). c crosslinked: Better solvent resistance and softening temperature than thermoplastic type (Tp) without the need for heat treatment. Heat treatment may, however, improve the solvent resistance still
