This CSA Standard is joint with UL Standard 1786. 1 Scope 1.1 This Standard applies to direct plug-in nightlights not exceeding 10 W input, for indoor use only, in non-hazardous locations and intended to be used in accordance with the Canadian Electrical Code, Part I, CSA C22.1, and the National Electrical Code, ANSI/NFPA 70. Light source types include incandescent candelabra base lamps,…

1 Scope This Standard applies to HRC non-renewable cartridge current-limiting fuses of the HRCI-MISC (Form I) type rated 600 A or less and 600 V ac or less, and to HRC non-renewable cartridge current-limiting fuses of the HRCII-MISC (Form II) type rated 1200 A or less and 600 V ac or less, that are intended to be used in accordance with the Canadian Electrical Code, Part I.

1. PURPOSE AND SCOPE 1.1 The procedures that follow can be used to analyze mixtures of many commonly occurring textile fibres. In selecting these procedures, a number of possible methods were considered. Interlaboratory analyses of prepared fibremixtures of known composition were carried out, and only those methods found to be satisfactory were accepted. In most cases, the scope of the method is…

1. OBJET 1.1 Les modes opératoires suivants peuvent servir à analyser des mélanges constitués d'un certain nombre de fibres textiles communes. Le choix de ces modes opératoires résulte de l'étude de plusieurs méthodes possibles. Des analyses interlaboratoires ont été effectuées sur des mélanges de fibres préparés de composition connue et seules les méthodes jugées satisfaisantes ont…

1 Scope This International Standard is applicable to flexible insulating covers (line hoses) for the protection of workers from accidental contact with live or earthed electrical conductors and for the avoidance of short circuits during live working. 1.1 Classes Five classes of conductor covers, differing in electrical characteristics, are provided and designated as class 0, class 1, class 2,…

ISO/IEC 14496-3:2005 (MPEG-4 Audio) is a new kind of audio International Standard that integrates many different types of audio coding: natural sound with synthetic sound, low bitrate delivery with high-quality delivery, speech with music, complex soundtracks with simple ones, and traditional content with interactive and virtual-reality content. By standardizing individually sophisticated coding…

ISO 7663:2005 specifies: physical and chemical tests on raw rubbers;standardized materials, a standardized test formulation, and the equipment and processing methods for evaluating the vulcanization characteristics of all types of halogenated isobutene-isoprene rubber (BIIR and CIIR).

Deals with the limitation of harmonic currents injected into the public supply system. Specifies limits of harmonic components of the input current which may be produced by equipment tested under specified conditions. Harmonic components are measured according to Annexes A and B. This part of IEC 61000 is applicable to electrical and electronic equipment having an input current up to and…
