Scope 1.1 These requirements cover FITTINGS for use with cable and conduit intended for installation in accordance with the National Electrical Code, ANSI/NFPA 70, the Canadian Electrical Code (CEC), Part I, CSA C22.1, and the Standard for Electrical Installations, NOM-001-SEDE. 1.2 These requirements cover CONDUIT LOCKNUTS, conduit BUSHINGS, metal stud BUSHINGS, CONDUIT BODIES, and entrance…

IEC 61034-1:2005+A1:2013 Provides details of the test apparatus to be used for measuring smoke emission when electric or optical fibre cables are burnt under defined conditions, for example, a few cables burnt horizontally. The light transmittance (lt) under flaming combustion and smouldering conditions can be used as a means of comparing different cables or complying with specific requirements.…

Scope 1.1 Scope This Standard specifies requirements for controlling hazardous energy associated with potentially harmful machines, equipment, and processes (including mobile machinery and equipment - see Annex L).Where a CSA Standard or other recognized Standard exists for a specific type of machinery, equipment, or process, it should be used with this Standard to provide the most effective…

Scope 1.1 This Standard applies to surge protective devices (SPDs) intended for a) permanently connected applications designed for limiting surge voltages and discharging surge currents; b) use on 50/60 Hz circuits over 42 V and up to 750 V ac; c) installation on the load side of the main overcurrent protective device; and d) indoor or outdoor use in accordance with the Canadian…

This part of ISO 7211 specifies three methods for the determination of the number of threads per centimetre in woven fabrics. Any of the three methods may be used, the choice depending on the character of the fabric. However, in case of dispute method A is recommended. Method A: Dissection of fabric, suitable for all fabrics. This is the most laborious method but has fewer limitations than…

IEC 62271-109:2008+A1:2013 is applicable to a.c. series capacitor by-pass switches designed for outdoor installation and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 52 kV. It is only applicable to by-pass switches for use in three-phase systems. This standard is also applicable to the operating devices of by-pass switches and to their auxiliary equipment. This…

IEC 60747-5-5:2007+A1:2013 gives the terminology, essential ratings, characteristics, safety test as well as the measuring method for photocouplers (or optocouplers). NOTE The word "optocoupler" can also be used instead of "photocoupler". This standard replaces the clauses for photocouplers (or optocouplers) described in IEC 60747-5-1, IEC 60747-5-2 and IEC 60747-5-3,…

1. SCOPE 1.1 This standard applies to two types of ultra low-sulphur diesel fuel, Type A and Type B, suitable for use in highspeed diesel engines, in on-road and off-road applications and in select medium speed applications. 1.2 Type A is intended for use in selected applications or when ambient temperatures require better low-temperature properties than Type B. 1.3 Fuel meeting this standard may…

1. OBJET 1.1 La présente norme s’applique à deux types de carburant diesel à très faible teneur en soufre, type A et type B, convenant aux moteurs diesels à régime élevé, aux applications sur route et hors route et à certains moteurs à régime moyen. 1.2 Le carburant de type A est destiné à certaines applications, ou lorsqu’un rendement à basse température supérieur à celui du carburant diesel de…

1. SCOPE 1.1 This standard describes two grades of propane used only for fuel purposes. These grades consist mainly of C3 compounds. 1.1.1 Grade 1 is intended for use in internal combustion engines and for general industrial and commercial fuel applications. Grade 1 maintains a minimum octane quality by limiting concentrations of low-octane components (see footnote 6). Note: The…
