3.1 Resistance or voltage values alone do not provide sufficient detail for an engineering evaluation of contact noise. This practice lists the test conditions that should be reported with noise measurements and indicates some conditions (open circuit voltages, currents, etc.) that...
5.1 This test method is useful for the comparison of materials, as a quality control test, and for specification purposes. 5.2 This test method is useful in the selection and use of materials in wires, cables, bushings, high-voltage rotating machinery, and other electrical...

Specifies the quality, performance and test procedures for electro-mechanical relays for control and switching circuits whose rated coil voltages do not exceed 500 V a.c. or 440 V d.c. and whose contact ratings do not exceed 20 A a.c. or d.c., 500 V a.c. or 440 V d.c. Also...
Ratings, characteristics and inspection requirements to be included in detail specifications for use in the CECC system of harmonized specifications. Applications include low frequency amplification, high frequency amplification, switching, chopper, voltage-controlled, low level d.c....
The efficiency of light-emitting diodes is known to vary with the carrier density of the starting material. This procedure provides a technique to prepare specimens in which the Hall carrier density can be measured in a region typical of that in which devices are fabricated. This quantity, which is...
