Methods of measurement for equipment used in terrestrial radio-relay systems - Part 1: Measurements ...
Gives standard conditions of measurement and methods of measuring the characteristics common to sub-systems of terrestrial line-of-sight radio-relay systems and to simulated radio-relay systems using frequency modulation. The tests described are limited to analogue transmission systems. Standardizes the conditions and methods of measurement to be used to ascertain the performance of terrestrial…
Ceramic dielectric disk-style rotary variable pre-set capacitors: Grade 2. Part 1: General requireme...
Describes the tests on capacitors to establish as far as possible under laboratory conditions: their suitability for use over stated ranges of temperature, air pressure and humidity; their ability to withstand specified conditions of mechanical shock such as are to be expected under transit or operational conditions: their
ability to withstand the rigours of normal assembly processes attendant on…
