IEC 61095:2023 applies to electromechanical air break contactors for household and similar purposes provided with main contacts intended to be connected to circuits the rated voltage of which does not exceed 440 V AC (between phases) with rated operational currents less than or equal to 63 A for utilization category AC-7a, and 32 A for utilization categories AC‑7b, AC‑7c and AC-7d (expressed in…

This test method covers the use of an impedance tube, two microphone locations and a frequency analysis system for the determination of the sound absorption coefficient of sound absorbing materials for normal incidence sound incidence. It can also be applied for the determination of the acoustical surface impedance or surface admittance of sound absorbing materials. As an extension, it can also…

This document specifies safety, construction, performance and testing requirements for multifunctional controls with integral overpressure protection safety function (OPSF) intended for use with portable gas appliances. This document is applicable to: —     multifunctional controls which consist of a pressure-limiting device and at least one or more controls, including but not limited to a manual…

This document specifies measures applicable to the class B2 voltage DC bus of a supply system which is intended to power detachable electrical CS(s). —     electrical specification of the high power interface —     operating modes (e. g. initialization, normal operation, energy feedback, connect/disconnect procedures and disconnect in case of malfunction) —     Communication parameters (basic…

1 Scope 1.1 The requirements of this standard apply to off-board unidirectional and bidirectional equipment rated 1000 Vac and 1500 Vdc or less, that transfers electrical energy between an electric vehicle and off board loads as well as operating in parallel with an electric power system, such as the electric utility grid, using a permanently attached vehicle connector. Equipment that has…

IEC 60512-99-003:2023 is used for the assessment of connectors within the scope of SC 48B that are used in balanced single-pair communication cabling with remote power, in support of e.g., IEEE 802.3 remote powering applications for point-to-point connections. The object of this document is to detail a test schedule to determine the ability of sets of single-pair connectors as defined in the IEC…
