Specifies performance requirements for the subfamily as shown in the title. This publication forms part of a series dealing with measuring relays with more than one input energizing quantity and for which IEC 60255-6 gives the general requirements.

This standard includes two types of tests: -the shock test (on energized and non-energized specimen), -the bump test (on non-energized specimen).[
]These requirements are applicable only to measuring relays and protection equipment in a new condition.

Specifies the general requirements for impedance measuring relays. Covers test methods and methods of presenting relay characteristics and performance.

Specifies IEC type designation, dimensions, characteristics (climatic, electrical and mechanical) and test schedules for one, two, three and four-pole centrally bush mounted miniature lever switches for use in electrical and electronic equipment, having a rated voltage not exceeding 250 V and a rated current not exceeding 6 A. The switches covered by this specification are not intended for use as main switches and therefore the requirements of IEC 65 do not apply.

Specifies IEC type designation, construction, dimensions, electrical ratings for 12-position switches. Establishes a schedule for type tests.

Deals with terminology, classification into groups, electrical ratings, marking, IEC type designation, type tests, standard conditions for testing, visual inspection, dimensions, clearances and creepage distances, electrical tests, mechanical tests, climatic tests and endurance tests.
