Analogue voltage ranges and logic levels for mains operated nuclear instruments.
Applies to all mains operated nuclear electronics instruments used in research laboratories, radiation detectors excepted, and establishes standard voltage ranges and maximum permissible output voltages for analogue signals and output impedances for analogue circuits.
Air dielectric rotary variable capacitors. Part 1: General requirements for tests and measuring meth...
Describes tests that establish, as far as possible under laboratory conditions, their suitability for use and their ability to withstand specified conditions of mechanical shock and rigours of normal assembly processes. A guide to the use and testing of air dielectric rotary variable capacitors is given in an appendix.
Applies to new voltage transformers for use with electrical measuring instruments and electrical protective devices at frequencies from 15 Hz to 100 Hz.
The general requirements apply to all voltage transformers, but, for certain types, e.g. capacitor voltage transformers, the requirements are subject to the modifications stated in the appropriate chapter. Although the requirements relate…
Lays down the conditions and procedure for carrying out impulse tests on cables and their accessories, with a view to rationalizing the practice in different laboratories, and thus to facilitate valid comparisons between the results obtained on cables made to different specifications.
Notes:
1.This publication should be read in conjunction with IEC 60060 and 60141.
2.For voltage measurements…
Construction and Test of Electrically Equipped Machine Tools
1. Scope
This Specification applies to machine tools, not portable by hand, (but which may have certain portable parts), having electrical equipment mounted thereon and designed to be installed and employed in accordance with the rules of Part I of this Code.
It does not apply to:
(a) Machine tools which produce hazardous atmospheres due to their operation and therefore require the…
Laboratory test of dust collection systems utilizing filter media with automatic online cleaning — P...
This Standard specifies the standard test method useful to assess the performance of dust collection systems utilizing integrated fans (compact type dust collector), which shall be applied with or without flow control.
This standard is not intended to offer the superiority or inferiority of performance between dust collectors, but specifies a standard test method that provides users with…
Fans — Laboratory methods of testing air circulating fans
This standard shall be used as the basis for testing electrically powered air circulating fan heads and ceiling fans when air is used as the test gas. The scope is limited to air circulating fans with an input power greater than or equal to 125 W—except for ceiling fans that are larger than 1800 mm, which do not have a lower input power limit. The diameter of the fan being tested shall be limited…
Measurement of radioactivity — Gamma emitting radionuclides — Rapid screening method using scintilla...
ISO 19581 specifies a screening test method to quantify rapidly the activity concentration of gamma-emitting radionuclides, such as 131I, 132Te, 134Cs and 137Cs, in solid or liquid test samples using gamma-ray spectrometry with lower resolution scintillation detectors as compared with the HPGe detectors (see IEC 61563).
This test method can be used for the measurement of any potentially…
