Switching impulse tests on high-voltage insulators.
Applies to switching impulse tests on insulators intended for use on a.c. installations with highest voltage 300 kV and above. Defines switching impulse characteristics of insulators and prescribes the conditions under which the specified values of these characteristics shall be verified. Prescribes methods for switching impulse tests on insulators under standard conditions.
High-voltage metal-enclosed switchgear for rated voltages of 72.5 kV and above
Specifies requirements for gas-insulated metal-enclosed switchgear in which the insulation is obtained, at least partly, by an insulating gas other than air at atmospheric pressure, for alternating current of rated voltages of 72.5 kV and above, for indoor and outdoor installation, and for service frequencies up to and including 60 Hz. For the purpose of this standard the term
Safety in electro-heat installations - Part 2: Particular requirements for resistance heating equipm...
Cancels and replaces the previous edition which had the status of a report. Applies to direct and indirect resistance heating installations. Standardizes the safety requirements to be respected in the industrial furnaces energized with d.c. or a.c. single-phase or polyphase voltage of frequency up to 60 Hz.
Dimensional standardization of terminals for high-voltage switchgear and controlgear
Recommends diameters and lengths for terminals of cylindrical shape as well as the diameters and distances between the holes of terminals of rectangular shape. This publication has the status of a report.
Plugs and socket-outlets for domestic and similar general use. Standards.
Contains specification sheets for three groups of plugs and socket-outlets for domestic and similar general use:
Group A:American National Standards Institute (ANSI)
Group B:British Standards Institution (BSI)
Group C:International Commission on Rules for the Approval of Electrical Equipment (CEE)
This publication has the status of a technical report.
Supplement D - General principles of nuclear reactor instrumentation - Principles of instrumentation...
Applicable more particularly to instrumentation for pressurized water reactors. Deals in particular with measurements of neutron fluence rate (flux). The IEC 60231 series of standards is no longer up-to-date and will not be revised by IEC. The standards are maintained for the time being for bibliographical purposes and because they were used in the past for the design of nuclear power plants…
Environmental testing. Part 2: Tests. Test Ed: Free fall
Determines the effect on a specimen of standard treatments which are representative of the falls likely to occur during rough handling.
Has the status of a basic safety publication in accordance with IEC Guide 104.
