ISO 3581 specifies requirements for classification of covered electrodes, based on the all-weld metal chemical composition, the type of electrode covering and other electrode properties, and the all-weld metal mechanical properties, in the as-welded or heat-treated conditions, for manual metal arc welding of stainless and heat-resisting steels. It is a combined standard providing for…

IEC 61754-6-1:2003 defines the standard interface dimensions of simplified receptacles for the type MU family of connectors. Keywords: interface dimensions of simplified receptacles for type MU connectors.

1. Scope 1.1 This Standard specifies (a) general design requirements; (b) product marking and labelling; (c) test procedures; and (d) performance requirements for single-occupancy mobility aids that are intended to be transported in vehicles having a gross vehicle weight rating (GVWR) of less than 7000 kg (15 500 lb) and equipped to accommodate occupants who are seated in a mobility aid. See…

1. Scope 1.1 This Standard specifies (a) general design requirements; (b) performance requirements; (c) test methods; (d) requirements for product marking and labelling; and (e) requirements for instructions and warnings for MASOR systems intended for use with forward-facing mobility aids occupied by children and adults with mass of 22 kg or greater, travelling in personally licensed and public…

This National Standard of Canada is equivalent to International Standard CEI/IEC 61558-2-1:1997 (first edition 1997-02). 1 Scope Replacement: This part 2 of IEC 61558 applies to stationary or portable, single-phase or polyphase, aircooled separating transformers, associated or not, having a rated supply voltage not exceeding 1000 V a.c., a rated frequency not exceeding 500 Hz, and a…

This National Standard of Canada is equivalent to International Standard CEI/IEC 61558-2-2:1997 (first edition, 1997-10). 1 Scope Replacement: This part 2-2 of IEC 61558 applies to stationary or portable, single-phase or poly-phases, aircooled control transformers associated or otherwise having a rated supply voltage not exceeding 1 000 V a.c. or 1 415 V ripple free d.c. and rated…

This National Standard of Canada is equivalent to International Standard CEI/IEC 61558-2-4:1997 (first edition, 1997-02). 1 Scope Replacement: This part 2 of IEC 61558 applies to stationary or portable, single-phase or polyphase, air-cooled isolating transformers, associated or otherwise, having a rated supply voltage not exceeding 1000 V a.c. and rated frequency not exceeding 500 Hz,…

Applies only to newly manufactured static var-hour meters of accuracy classes 2 and 3, for the measurement of alternating current electrical reactive energy in 50 Hz or 60 Hz networks and it applies to their type tests only. For practical reasons, this standard is based on a conventional definition of reactive energy for sinusoidal currents and voltages containing the fundamental frequency only.…

Relates to emission and immunity test methods for electrical and electronic equipment using various types of transverse electromagnetic (TEM) waveguides. This includes open (for example, striplines and EMP simulators) and closed (for example, TEM cells) structures, which can be further classified as one-, two-, or multi-port TEM waveguides. The frequency range depends on the specific testing…
