IEC 61726:2015 describes the measurement of screening attenuation by the reverberation chamber test method, sometimes named mode stirred chamber, suitable for virtually any type of microwave component and having no theoretical upper frequency limit. It is only limited toward low frequencies due to the size of the test equipment, which is frequency-dependent and is only one of several methods of…

ISO 11972:2015 specifies cast steels for general corrosion-resistant applications. The grades covered by this International Standard represent types of alloy steel castings suitable for broad ranges of application which are intended for a wide variety of corrosion applications. NOTE Annex A gives information on ISO grade designation and available UNS numbers which are similar to the ISO…

ISO 19631:2015 specifies performance and quality requirements for the qualification and manufacture of standard tube fittings to ensure reliable performance in aircraft hydraulic 5 080 psi (35 000 kPa) systems. ISO 19631:2015 specifies baseline criteria for the design and manufacture of system fittings that are qualification tested on engines. ISO 19631:2015 covers fittings from size ?04 to ?20…

ISO/TS 14907-1:2015 specifies the test procedures of EFC roadside equipment (RSE) and on-board equipment (OBE) with regard to the conformance to standards and requirements for type approval and acceptance testing which is within the realm of EFC application specifically. ISO/TS 14907-1:2015 is restricted to systems operating within the radio emission, electromagnetic compatibility (EMC)…

1.1 This Standard applies to all types of laboratory fume hoods, except for ductless fume hoods. Note: Ductless fume hoods should not be considered acceptable substitutes for ducted fume hoods. Some jurisdictions prohibit use of ductless fume hoods with certain chemicals. For these reasons, ductless fume hoods have not been included in this Standard. 1.2 This Standard specifies a) safety…

1.1 This Standard applies to assemblies of resistors, enclosures, and other components that provide high impedance grounding for the purpose of controlling the ground fault current or the voltage to ground of an alternating current system, when installed in accordance with the Canadian Electrical Code, Part I. 1.2 This Standard applies to neutral grounding resistor assemblies rated for use on…

This part of IEC 61000, which is informative in its nature, provides guidance on principles that can be used as the basis for determining the requirements for the connection of disturbing installations to low voltage (LV) public power systems. For the purposes of this part of IEC 61000, a disturbing installation means an installation (which may be a load or a generator) that produces disturbances…

1.1 This Standard contains requirements for alarm initiating devices, supervisory detecting devices and accessories for automatic water supply control valves for attachment to water type extinguishing systems (such as, but not limited to wet, dry, pre-action and deluge type sprinklers, residential sprinklers, water mist suppression systems, water spray fixed extinguishing systems, water motors…
