This recommendation relates to ceramic dielectric, disc-style, rotary variable pre-set capacitors for domestic applications (grade 2) intended for use in electronic equipment and for width only a comparatively small number of movements are required during their life. This recommendation does not apply to Grade 1 components intended for professional applications. The object of the test on capacitors described herein is to establish as far as possible under laboratory conditions: a) their suitability for use over stated ranges of temperature, air pressure and humidity; b) their ability to withstand specified conditions of mechanical shock such as are to be expected under transit or operational conditions; c) their ability to withstand the rigours of normal assembly processes (e.g., soldering) attendant on their incorporation in equipments, without detritement to a) and b) above.
