Methods of measurement of performance of electric irons for household or similar use
States and defines the principal performance characteristics of electric irons for household or similar use which are of interest to the user and describes the standard methods for measuring these characteristics. Safety and performance requirements are not considered.
Supplement C - Essential ratings and characteristics of
semiconductor devices and genera...
Deals with transistors and considers collector-base capacitance of transistors, gives voltage ratings and measurable characteristics limiting the working voltages, indicates methods of measuring thermal resistance and defines switching and high-
frequency parameters.
Rules for ohmic resistors used in the power circuits of electrically powered vehicles
Are intended to define the conditions which resistors should satisfy, the tests to check that the conditions are in fact satisfied, and the descriptive marking to be applied on the rated plate of the resistors.
International code for testing of speed governing systems for hydraulic turbines
Defines the terms and quantities necessary to describe the regulating behaviour of the speed governing system. It presents methods of testing and ways of measuring the quantities involved so that the performance and behaviour of the governing system can be ascertained and the guarantees verified.
Rotating electrical machines - Part 6: Methods of cooling rotating machinery
Identifies circuit arrangements and movement methods of the coolant. Classifies methods of cooling and gives a designation system for them. Complete and simplified designations are defined.
Methods of measurement of performance of vacuum cleaners for household and similar use
States and defines the principal performance characteristics of vacuum cleaners which are of interest to the user and describes the standard methods for measuring these characteristics.
Replaces IEC 272. Covers the selection and implementation of reliability and maintainability activities, appropriate to each of the defined phases of the life of electrotechnical products. Provides management guidelines for establishing reliability and maintainability programmes applicable in varying degrees to the complete life cycle of electrotechnical products. Serves as a general standard…
