1.1 This European Standard is applicable to the erection and operation of fixed and temporary electrical test installations.1.2 Compliance with this European Standard is not necessary, if contact with live parts presents no danger. This is the case when one of the following conditions is satisfied at live exposed points:a) the voltage at frequencies above 500 Hz does not exceed 25 V a.c. or 60 V d.c. and complies with the requirements for SELV or for PELV in accordance with HD 60364-4-41;b) in case of voltages at frequencies up to 500 Hz exceeding 25 V a.c. or 60 V d.c., the resultant current through a non-inductive resi¬stance of 2 k¿ does not exceed 3 mA

This European Standard specifies general requirements for construction, testing and performance, and describes the test methods that apply to portable, transportable and fixed apparatus for the measurement of the oxygen concentration in gas mixtures indicating up to 25 % (v/v). The apparatus, or parts thereof, may be intended for use in potentially explosive atmospheres (see 4.1) and in mines susceptible to firedamp.In the case of inert gas purging (inertization), it applies also to apparatus with an oxygen measuring function for explosion protection.NOTE Commonly used oxygen sensors in commercial equipment for industrial application are:a) paramagnetic sen

This European Standard specifies minimum requirements and tests for electrical apparatus for the detection and measurement of combustible gases, toxic gases or oxygen using software and/or digital technologies. Additional requirements are specified if compliance with safety integrity level 1 (SIL 1) according to EN 61508 series is required for low demand mode of operation.NOTE 1 It is recommended to apply this European Standard for apparatus used for safety applications with SIL-requirement 1 instead of EN 50402. However, the technical requirements of EN 50271 and EN 50402 are the same for SIL 1.NOTE 2 For fixed apparatus used for safety applications with S

This International Standard is applicable to high-current testing and measurements on both high-voltage and low-voltage equipment. It deals with steady-state and short-time direct current (as e.g. encountered in high-power d.c. testing), steady-state and short-time alternating current (as e.g. encountered in high-power a.c. testing), and impulse-current. In general, currents above 100 A are considered in this International Standard, although currents less than this can occur in tests. NOTE This standard also covers fault detection during, for example, lightning impulse testing. This standard: ? defines the terms used; ? defines parameters and their tolerances; ? describes methods to estimate uncertainties of high-current measurements; ? states the requirements which a complete measuring system shall meet; ? describes the methods for approving a measuring system and checking its components; ? describes the procedure by which the user shall show that a measuring system meets the requirements of this standard, including limits set for uncertainty of measurement.

IEC 60052 sets forth recommendations concerning the construction and use of standard air gaps for the measurement of peak values of the following four types of voltage : a)Alternating voltages of power frequencies; b)Full lightning impulse voltages; c)Switching impulse voltages; d)Direct voltages. Air gaps constructed and used in accordance with this standard represent IEC standard measuring devices in accordance with IEC 60060-2 and are primarily intended for performance checks of high voltage measuring systems .
