21、eets Based on Thermosetting Resins for Electrical Purposes73. Terminology3.1 DefinitionsFor definitions of terms used in this specification, refer to Terminologies D883 or D1711.4. Types and Grades4.1 Laminated materials covered by this specification are classified in accordance with the types of re

22、inforcement used in theirmanufacture, and the electrical, mechanical, and heat-resisting characteristics of the finished products (Note 2).NOTE 2Further descriptive information regarding these various types and grades of laminated thermosetting materials is given in Table 1 andAppendix X1 Appendix X

23、3. Appendix X3 also includes tables covering engineering information on other properties of the various grades of laminatedthermosetting products that are not included in these specification requirements.5. Forms5.1 Laminated thermosetting materials are available in four forms: sheets, tubes (Note 3

24、), rods (Note 4), and molded shapes(Note 5), as indicated in Table 2. This specification covers the material in three forms: sheets, tubes of two classes (rolled andmolded), and molded rods. The classes of tubes desired shall be specified by the purchaser in the contract or order. In cases wherethe

25、purchaser desires a particular class of molded rod the purchaser shall so specify.NOTE 3Tubes are made of laminations of fibrous sheet impregnated material, rolled upon mandrels under tension or between heated pressure rolls,or both. They are of two classes, rolled and molded. Rolled tubes are oven-

26、baked after rolling on the mandrels. Molded tubes are cured in molds underheat and pressure.NOTE 4Molded rods are composed of laminations of impregnated sheet material molded in cylindrical molds under heat and pressure, and thenground to size. Molded rods are of two classes made by winding the impr

27、egnated sheet convolutely before molding or by forming strips in the moldingoperation.Machined rods, manufactured from certain grades of sheet material, are not covered by this specification. In rods machined from sheets, the laminationsare parallel chords of a circular cross-section. In general, th

28、e properties of these rods conform to those of the grade of sheet stock from which they arecut. This type of rod has the potential to be low in flexural strength when stress is applied perpendicular to the lamination.NOTE 5Molded shapes are composed of impregnated sheet materials cut into various si

29、zes and shapes to fit the contours of a mold, and molded underheat and pressure. In special cases some macerated material is used in combination with impregnated sheet materials, depending upon the design of thepiece. The requirements of this specification, particularly with regard to mechanical pro

30、perties, cannot be considered as applying to molded shapes, exceptfor rectangular and square tubes, since such properties will depend to a considerable extent upon the design of the piece.6. General Requirements6.1 Materials and WorkmanshipLaminated material shall be uniform in quality. It shall be

31、free of blisters, wrinkles, or cracksand shall be reasonably free of other small defects such as scratches, heat marks, and so forth, as defined in Terminology D883.Tubes of any grade having wall thickness greater than 12 in. (13 mm) and molded paper-base rods (Grades XX and XXX) havingdiameters gre

32、ater than 1 in. (25 mm) have the potential to show checks or cracks between the laminations on machined or sawededges.6.2 Finish and ColorRequirements for finish (Note 6) and color (Note 7) shall be as specified by the purchaser in the contractor order.5 Available from National Electrical Manufactur
