33、ied. 3.4.3 Finish. All exposed metallic surfaces (case, hardware, and terminals) shall be suitably protected against corrosion by plating, solder coating, or other means. The finish shall provide good electrical contact when used on a terminal or as a conductor (see 6.4); shall have uniform texture

34、and appearance; shall be adherent; and shall be free from blisters, pinholes, and other defects that may affect the protective value of the coating. Pure tin plating is prohibited (see 3.3.2).

36、ere shall be no evidence of liquid leakage. 3.5.2 All other units. When filters are tested in accordance with 4.6.2.2, there shall be no continuous stream of bubbles emanating from the filter, nor shall there be any evidence of leakage of compound from the body of the filter. 3.6 Capacitance to grou

37、nd (when specified; see 3.1). When filters are tested in accordance with 4.6.3, the capacitance to ground shall be as specified. 3.7 Temperature rise. When filters are tested in accordance with 4.6.4, the maximum temperature rise shall be as specified (see 3.1). 3.8 Dielectric withstanding voltage.

38、When filters are tested in accordance with 4.6.5, there shall be no breakdown, flashover, or impairment of any characteristic qualities sufficient to cause failure of the filter. 3.9 Barometric pressure (reduced). When filters are tested in accordance with 4.6.6, there shall be no breakdown, flashov

39、er, or impairment of any characteristic qualities sufficient to cause failure of the filter. 3.10 Insulation resistance (terminal to ground). When measured in accordance with 4.6.7, the insulation resistance of any filter section shall be not less than the applicable value shown on figure 1 or as sp

40、ecified (see 3.1). The value of insulation resistance varies with temperature, and it is necessary to apply a correction factor to measurements made at a temperature other than 25C. Correction factors for measurements made at temperatures between 20C and 35C are given in table I. The required value

41、of insulation resistance shall be multiplied by the correction factor to determine the new value required at the test temperature. TABLE I. Insulation-resistance correction factors.
