7、 foreword This British Standard has been prepared by Subcommittee GEL/15/3 and is the English language version of EN 61629-1:1996 Aramid pressboard for electrical purposes Part 1: Definitions, designations and general requirements published by the European Committee for Electrotechnical Standardizat
8、ion (CENELEC). It is identical with IEC1629-1:1996 published by the International Electrotechnical Commission (IEC). IEC 1629 consists of the following parts, under the general title Aramid pressboard for electrical purposes: Part 1: Definitions, designations and general requirements; Part 2: Method
9、s of test; Part 3: Specifications for individual materials. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from
10、legal obligations.

Materials which conform
24、to this specification meet established levels of performance. However, the selection of a material for a specific application should be based on the actual requirements necessary for the adequate performance in that application and not based on this specification alone. While the primary use of thes
25、e materials is an electrical insulation, there is no intent to discourage their use in other applications for which their properties may make them suitable. 2 Definitions For the purpose of this part of IEC1629, the following definitions apply: 2.1 aramid pressboard board produced normally on an int
26、ermittent board-making machine from pulp made from high temperature resistant aramid fibres and fibrids which are produced of synthetic polyamid having at least85% of amide linkage attached directly to two aromatic rings 2.2 calendered aramid pressboard aramid pressboard which is densified by a subs
27、equent calendering process 2.3 high-density aramid pressboard aramid pressboard which is densified by a subsequent heat-pressing operation 3 Designation The aramid pressboard materials shall be designated as follows: 4 General requirements 4.1 Composition The material shall be manufactured from aram
28、id high temperature resistant fibres, according to the definition given in2.1. 4.2 Finish Boards shall be plane, free from local deformations or surface defects. All boards shall be supplied with trimmed edges. The surface texture of types APB-LD, APB and APB-C shows a cloth mark impression. Type AP
29、B-HD has a smoother surface than the other types of aramid pressboard and an off-white aspect. 4.3 Machinability When cut, sawn, punched or otherwise machined in accordance with the recommendations of the supplier, the board shall not show any undue splitting, cracking, or ragging of the edges. Type
30、 Description Apparent density (g/cm 3 ) APB-LD Low density 0,5 to 0,7 APB Standard density 0,6 to 1,0 APB-C Medium density/calendered 0,8 to 1,1 APB-HD High density/heat compressed 1,0 to 1,2EN61629-1:1996 4 BSI 09-1999 5 Thickness 5.1 Preferred nominal thicknesses of the boards 5.2 Deviation of thi
31、ckness The deviation from nominal thickness shall not exceed the values which will be given in the sheets of the futureIEC 1629-3 1) . 6 Conditions of supply Packaging The material shall be supplied in a packaging which ensures adequate protection during handling, transportation, and storage. 7 Mark
32、ing 7.1 Identification Every material consignment shall be legibly marked with a clearly identifiable code. 7.2 Marking material Any marking material used on the pressboard shall be electrically neutral, oil resistant and non-polluting to oil.
