17、 Use This PublicationFirst, review Part 1 for general information. Then in Part 2, locate the specification for the type of insulation and conductor of interest. Part 2 is arranged in numerical order as shown beginning on page 14. The dimensions for each Part 2 MW type are provided in Part 1, beginn

18、ing with Table 1. The specification in Part 2 will indicate the requirements to be met and will refer to the test procedures and corresponding test values to be attained in Part 3.Part 1 of this publication deals with information common to all types of magnet wire: ordering information, general mate

19、rial requirements, general test conditions, definitions, and manufacturing data in support of thermal rating. This part also includes dimensions with metric equivalents for all bare, minimum insulation increase, and overall dimensions for all Part 2 MW specification requirements. Part 2 consists of

20、product specifications requirements (other than dimensions) for magnet wire with different types of coatings and/or coverings. Insofar as possible, the product specifications are complete on one sheet, since they are arranged to include only one insulation or covering per sheet. The title on each sh

21、eet identifies the product. Example: MW 15-C, Polyvinyl Acetal Round Copper Magnet Wire. MW 15-A covers the aluminum version of the same generic product.Part 3 contains the test procedures to be followed and corresponding tables of specific test values to be attained in determining compliance with t

22、he requirements given in Part 2. The requirements are consolidated with the test procedures and testing parameters for a given property. An index of the main test paragraphs is provided, beginning on page 14, Part 3 Test Procedures, in the Table of Contents.Annex A provides a cross reference between

23、 test procedures in this standards publication and those published by the American Society for Testing and Materials (ASTM). Annex B consists of definitions, requirements, and recommended test procedures for reusable magnet wire packaging, standardized dimensions for spools and reels, and formatting

24、 for the labeling of magnet wire products.Annex C provides a cross reference between NEMA and IEC magnet wire specifications.Annex D provides the formulas for determining dimensional requirements of round film-insulated magnet wire and dielectric breakdown, as well as cross-sectional area and resist

25、ance calculations.Annex E provides the dimensional criteria for ranges of sizes of rectangular bare, film, and fabric magnet wire products, setting the general rules and guidelines for various traditional yet non-standard rectangular magnet wire products.Annex F provides properties of selected refri

26、gerants determined as suitable alternatives to refrigerant R22 in the Refrigerant Extraction Test, clause 3.55.Annex G provides recommended winding tensions for round copper and aluminum magnet wire to ensure that wire, as it is de-reeled, is not stretched beyond end user requirements.Annex H provid
