The major changes from EN 60893-1:1994 are the following: a) new material types have been included; b) changes have been made to the property requirements of some existing types; c) a new method for testing permittivity and dissipation factor has been added; d) all non-specification data for
17、 each type has been moved to a new Part 4 document IEC/TR 60893-4: Typical values. The following dates were fixed: latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2004-12-01 latest date by which the national
18、 standards conflicting with the EN have to be withdrawn (dow) 2007-03-01 Annex ZA has been added by CENELEC. _ Endorsement notice The text of the International Standard IEC 60893-1:2004 was approved by CENELEC as a European Standard without any modification. _ Page2 EN608931:2004INTRODUCTION This pa
19、rt of IEC 60893 is one of a series which deals with industrial rigid laminated sheets based on thermosetting resins for electrical purposes. The series consists of four parts: Part 1: Definitions, designations and general requirements (IEC 60893-1) Part 2: Methods of test (IEC 60893-2) Part 3: Speci
20、fications for individual materials (IEC 60893-3) Part 4: Typical values (IEC 60893-4) IEC 60893-1 specifies definitions, designations and general requirements used in this standard.

21、 PURPOSES Part 1: Definitions, designations and general requirements 1 Scope This part of IEC 60893 contains the definitions related to, and the general requirements to be fulfilled by, industrial rigid laminated sheets for electrical purposes, made with any of the following resins as the binder: ep
22、oxy (epoxide), melamine, phenolic, polyimide, silicone and unsaturated polyester. The following reinforcements may be used either singly or in combination; cellulosic paper, cotton cloth, glass cloth, glass roving, glass mat, polyester cloth and wood veneers. Materials which conform to this specific
23、ation meet established levels of performance. However, the selection of a material by a user for a specific application should be based on the actual requirements necessary for adequate performance in that application and not based on this specification alone. 2 Normative references The following re
24、ferenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60893-2, Industrial rigid laminated sheets based on thermoset

27、ayers of reinforcement that have been impregnated with thermosetting resin and bonded together under heat and pressure to form a single piece NOTE Other constituents, for example colouring matter, may be incorporated.

28、e groups, which is formulated to enable cross-linking 3.3 melamine resin amino resin made by polycondensation of melamine with formaldehyde or another compound that is capable of providing methylene bridges 3.4 phenolic resin generic term for a class of resins made by the polycondensation of phenol,
29、 its homologues and/or derivatives, with formaldehyde 3.5 unsaturated polyester resin polymer consisting of chains with repeated structural units of the ester type with carbon-carbon unsaturation, which permits subsequent cross-linking with an unsaturated monomer or pre- polymer 3.6 silicone resin r
30、esin in which the main polymer chain consists of alternating silicon and oxygen atoms, with side groups containing carbon atoms, which is formulated to enable cross-linking 3.7 polyimide resin synthetic resin obtained by polycondensation of aromatic diamines and aromatic dianhydrides 4 Designation T
31、he sheets covered by this standard are classified into types, which differ in the resin and reinforcement employed and in their distinguishing properties. The sheets are designated by: the IEC standard number; a two-letter abbreviation denoting the resin; a second two-letter abbreviation, denoting t
32、he reinforcement; a serial number; nominal thickness width length, in mm. Example of designation: Industrial rigid laminated sheet - PF CP 201 with a nominal thickness of 10 mm, 500 mm wide, 1 000 mm long.

34、t) is used for those laminates containing more than one type of reinforcement. The actual composition is given in the appropriate Part 3 specification sheet. NOTE 2 Table 1 of IEC 60893-3-1 lists the combinations of resins and reinforcements that constitute types covered by this standard. 5 General
35、requirements All material in any one consignment shall have properties within the limits of this standard. 5.1 Appearance The laminates shall be free from blisters, wrinkles and cracks, and reasonably free from other defects, for example scratches, dents, ripples and discoloration. A small amount of
36、 mottle is permissible. 5.2 Sheet sizes Sheet sizes are determined by agreement between purchaser and supplier. Sheets shall be supplied in the trimmed condition, unless otherwise specified in the relevant Part 3 specification or as agreed between purchaser and supplier. 5.3 Thickness The nominal th
37、ickness shall be one of the preferred thicknesses given in Table 1, unless otherwise agreed between purchaser and supplier. The deviation from the nominal thickness of a sheet measured according to IEC 60893-2, shall not exceed the appropriate value specified in Part 3. 6 Conditions of supply The ma
38、terial shall be supplied in a packing material that ensures adequate protection during transport, handling and storage. The IEC designation of the material and the number of sheets or the mass shall be clearly marked on the outside of each package. Where different types of sheets are contained in th
39、e same package, the required information may be on a note accompanying the package. Any marking on individual sheets shall be as specified in the purchase contract. Where marking is carried out with a stamp, the stamping ink used shall not impair the electrical properties of the material. Page6 EN60
