1 Scope This Standard is applicable to portable voltage detectors, with or without built-in power sources, to be used on electrical systems for voltages of 1 kv to 52 kV a.c., and frequencies from 15 Hz to 60 Hz. It applies only to capacitive voltage detectors used in contact with the part to be tested, as a single unit including its insulating pole as covered by CAN/ULC-D61235-00 or CAN…

1 SCOPE This part of IEC 61243 is applicable to two-pole voltage detectors to be used on electrical systems for nominal voltages not exceeding 1 000 V a.c. and/or 1 500 V d.c. and below 500 Hz (nominal frequencies). The detector types are classified as follows: voltage class A: up to and including 500 V a.c./750 v d.c.; voltage class B: up to and including 1 000 V a.c./1 500 V d.c.…

1. Scope 1.1 This Standard provides requirements for the design, manufacture, and quality control of all types of concrete poles. 1.2 The provisions of this Standard are applicable to poles manufactured by the casting process and the spinning process. 1.3 This Standard does not address the rules for determining the required strength or other functional properties of any pole application…

Specifies limits for harmonic current emissions applicable to electrical and electronic equipment having an input current up to and including 16 A per phase, and intended to be connected to public low-voltage distribution systems. The tests according to this standard are type tests. Test conditions for particular equipment are given in annex C. For systems with nominal voltages less than 220 V (…

Standardizes the first order modeling of bond wires and the way bond wires are modeled in three dimensional electromagnetic field solvers. Describes the modeling of a bond wire from an integrated circuit die to a package lead in a ball or wedge type wire bond configuration.

This International Standard specifies general requirements, type tests and individual tests for marine electromagnetic compasses intended for steering purposes and/or taking bearings on board ships required by Chapter V of SOLAS, 1974 and the International Code of Safety for High-Speed Craft (HSC Code). The magnetic compasses specified in this standard shall apply to the ships the overall length…

1.1 General This part of ISO 230 specifies methods for testing the noise of stationary floor-mounted machine tools and related auxiliary equipment directly on the shop floor. The purpose of the measurements is to obtain noise-emission data for machine tools. The data obtained may be used for the purpose of declaration and verification of airborne noise emission from machine tools as specified in…

Specifies mechanical dimensions and certain electroacoustic characteristics for condenser microphones used as laboratory standards for the realization of the unit of sound pressure and for sound pressure measurements of the highest attainable accuracy. The specifications are intended to ensure that primary calibration by the reciprocity method can be readily carried out. Establishes a system for…

Defines the standard interface dimensions for the type Mini-MPO family of connectors characterized by a rectangular ferrule nominally 4,4 x 2,5 mm which utilize two pins of 0,7 mm diameter as its alignement.

1. SCOPe 1.1 This Standard applies to hand-fuelled solid-fuel fired space heaters of the radiant, convection or forced-circulating type, intended for residential heating. 1.2 This Standard applies to: A Space heaters having provision for venting directly to the outdoors; B Outdoor-aired space heaters intended for installation primarily in mobile…
