APPLICATION This specification was released originally for material used for electrical purposes. 3. REQU

3、IREMENTS 3.0 STANDARD REQUIREMENTS FOR PRODUCTION MATERIALS Material suppliers and part producers must conform to the Companys Standard Requirements For Production Materials (WSS-M99P1111-A). 3.1 WIRE SIZE The wire size shall be specified on the engineering drawing and/or release according to the Am

4、erican Wire Gage number desired. Example: #28 Gage ESF-M2L1-A. 3.2 CHEMICAL COMPOSITION The copper shall be of such quality and purity that the finished product shall have the physical properties and electrical characteristics herein required. 3.3 ELECTRICAL RESISTIVITY The electrical resistivity at

5、 a temperature of 20 C shall not exceed the following values: . 875.20 Ohm lb/mile2 (0.15328 Ohm g/m2) . 10.371 Ohm cmil/ft (0.017241 Ohm mm2/m) Resistance for any given wire must fall within the range obtained by calculating resistance for both the high and low diameter. The following formula may b

6、e used: Resistivity x Length Resistance = Cross Section Resistance will be in Ohms. Resistivity - 10.371 (0.017241) Length - feet (metre) Cross Section - circular mils (square millimetres) The circular mils for any diameter wire may be calculated by squaring the number of thousandths of inches in an

9、re shall be one continuous length for each spool. There shall be as few joints as possible in the copper and such joints as are necessary to bring the wire up to the required spool weight shall be made by brazing with silver solder, or by welding. The diameter of the wire at the joint shall be subst

10、antially the same as of any other point on the wire. The surface of the wire at the joint shall be smooth. The tensile strength of the wire at the joint shall be at least 80% of the tensile strength of the wire 3 - 4 ft (0.9 - 1.2 m) from the joint. 5. GENERAL INFORMATION The information given below

11、 is provided for clarification and assistance in meeting the requirements of this specification. 5.1 DENSITY For the purpose of calculating weights, the density of the copper shall be taken as 8.89 g/cm3 (0.32117 lb/in3) at 20 C.
