Dimensions of low-voltage switchgear and controlgear. Standardized mounting on rails for mechanical ...
Specifies dimensional and functional requirements for the compatible mounting of varied electrical devices on some types of rails in switchgear and controlgear assemblies. An appendix gives the standardized dimensions of steel mounting rails with Top Hat, C and G sections.
A second appendix provides an application guide for the use of rails.
Applies to traditional signal generators using tunable oscillators, to synchronizers for use with these, and to synthesizers and sweep generators. Does not apply to pulse generators.
Establishes the essential definitions; states the requirements intended for evaluating the electrical properties of signal generators; establishes a selection of standard performance characteristics from which the…
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.
Alpha, beta and alpha-beta contamination meters and monitors
Applies to assemblies designed to measure or detect the contamination of surfaces by alpha and/or beta radiation emitters. Lays down standard requirements: gives examples of acceptable methods; specifies general characteristics, general test conditions, radiation characteristics, electrical safety and environmental characteristics, and also the identification certificate.
Methods for measuring the performance of electric dishwashers
States and defines the characteristics of importance for determining the performance of household electric dishwashers in order to inform the consumer and describes the standard methods for measuring these characteristics.
The contents of the corrigendum of January 1998 have been included in this copy.
Methods of measurement of electro-acoustical characteristis of hearing aids. Part 4: Magnetic field ...
Applies to audio-frequency induction loop systems producing an alternating magnetic field and intended to provide an input signal for hearing aids operating with an induction pick-up coil. Specifies a standard value of magnetic field strength in audio-frequency induction loops for hearing aid purposes, such as will give an adequate signal-to-noise ratio without overloading the hearing aid.
Standard Method of Test for Flame Resistance - Methenamine Tablet Test for
Textile Floor Coverings
Intended for the determination of the flammability of finished
textile floor covering materials when exposed to an ignition
source (methenamine tablet) under specified conditions.
Standard Method for Fire Tests of Window and Glass Block Assemblies
1.1 This fire test method is applicable to window and glass block assemblies and
other light transmitting assemblies, for use in walls and partitions that are fire separations.
1.2 Tests made in conformity with this test method will register performance during
the test exposure and develop data to enable regulatory bodies to determine the suitability of
window assemblies for use in wall and…
