1. Scope and Field of Application This Standard is an Application Layer Standard within the Open Systems Interconnection framework defined by CSA Standard CAN/CSA-Z243.100. This Standard defines the services for interlibrary loan. These services are provided by the use of the ILL protocol in conjunction with supporting telecommunications services. This Standard does not specify…

Establishes these values for nuts, with a self-locking feature achieved by forming the upper portion of the nut element out-of-round, having these classifications and into which a sealing ring is incorporated to stop leakage past the threads. Is intended solely for the drawing up of complete product standards.

The volatile bases are distilled in alkaline medium under specified conditions and collected in a known volume of a standard volumetric hydrochloric acid solution in the presence of an indicator. The excess of the acid is titrated with a standard volumetric sodium hydroxide solution.

This standard is applicable to the calculation of short-circuit currents: -in low-voltage three-phase a.c. systems, -in high-voltage three-phase a.c. systems with nominal voltages up to 230 kV operating at nominal frequency (50 Hz or 60 Hz). This standardized procedure is given in such a form as to facilitate as far as possible its use by non-specialist engineers.

This standard applies to the following types of reactors: shunt reactors, current-limiting reactors including neutral-earthing reactors, damping reactors, tuning (filter) reactors, earthing transformers (neutral couplers), arc-suppression reactors, smoothing reactors, with the exception of the following reactors: small reactors with a rating generally less than 2 kvar single-phase and 10 kvar…

The Standard specifies the following characteristics of the oil. Appearance: Clear, mobile liquid. Colour: Pale yellow. Odour: Characteristic rose like, with grassy note. Relative density at 20/20 °C: 0,880 - 0,894. Refractive index at 20 °C: 1,4710 - 1,4780. Optical rotation at 20 °C: Range from - 1,4 to + 3 . Miscibility with 70 % (V/V) ethanol at 20 °C: 1 : 2. Acid value: Maximum 1,0. Further…

Applies to packaged heat-recovery ventilators that comprise factory-assembled elements including fans in which heat is transferred between two isolated airstreams, and that are intended for use in ducted supply and exhaust systems.

Parts 1 and 2 of this Standard apply to newly produced gas appliance connectors constructed entirely of new unused parts and materials, consisting of corrugated tubing depending on all-metal construction for gastightness, having nominal internal diameters of l/4, 3/8, 1/2, 5/8, 3/4 and 1, and having fittings at both ends provided with taper pipe threads for connection to a gas appliance and…

1. SCOPE 1.1 This standard applies to a low-density felt for cushioning, packing, padding and crating. This felt is not intended for use in ammunition components. 1.2 For more detailed information on intended uses, see par. 8.2.

1. Scope 1.1 This Standard applies to electrical metallic tubing fabricated from mild steel, aluminum alloy, or copper alloy intended for use as a metal raceway for the installation of wires and cables in accordance with the Rules of the Canadian Electrical Code, Part I.
