Standards
This standard covers thermoplastic and rubber tapes for use as electrical insulation at not more than 600 V and at 80 C (176 F) and lower temperatures on joints and splices in wires and cables in accordance with the National Electrical Code.. It is intended that rubber tape on a joint or splice be mechanically protected by a covering such as friction tape . Thermoplastic tape is acceptable without the additional mechanical protection.
BESP 100, Issue 1, November 1, 1996. This procedure describes the process for obtaining a Technical Acceptance Certificate (TAC) for Broadcasting Equipment.
This standard specifies legal metrology requirements for labelled packaged commodities with constant nominal content and subject to international trade. It also covers sampling plans for net content verification of goods declared in units of mass or volume.
This Recommendation specifies
· legal metrology requirements for prepackaged products (also called prepackaged commodities or prepackaged goods) labeled in predetermined constant nominal quantities of mass, volume, linear measure, area, or count, and
· sampling plans and procedures for use by legal metrology officials in verifying the quantity of product in prepackages.
NOTE: The sampling plans are not recommended for use in the quantity control processes of the packer.
These requirements cover ballasts of the resistance, reactance, and electronic (solid state) types for use with fluorescent lamps involving a potential of 2500 volts or less in accordance with the National Electrical Code, NEPA 70. A fluorescent lamp ballast may be determined by investigation to be acceptable for use, in a fixture or other device, with electric-discharge lamps of other than the fluorescent type. A product that contains features, characteristics, components, materials, or systems new or different from those in use when the standard was developed, and that involves a risk of fire, electric shocks, or injury to persons shall be evaluated using the appropriate additional component and end-product requirements as determined necessary to maintain the level of safety for the user of the product as originally; anticipated by the intent of this standard.
These requirements cover portable, stationary, and fixed uninterruptible power supplies (UPS) rated 600 volts or less ac or dc that are intended for installation in accordance with the National Electrical Code, NFPA 70. During intended operation, the UPS allows the utility to deliver ac and dc power to the connected load through either the power conversion portion of the UPS or a bypass source. The power conversion portion of the UPS consists of a rectifier and an inverter. During periods of power fluctuations, or power outage, or both, the connected load receives ac and dc power from the battery supply and power conversion portion of the UPS.
These requirements cover temporary-use, seasonal decorative-lighting products and accessories with a maximum input voltage rating of 120 V to be used in accordance with the National Electrical Code, ANSI/NFPA 70. Temporary-use is considered to be a period of installation and use not exceeding 90 days. 1.2 These requirements cover factory-assembled seasonal lighting strings with push-in, midget-screw, or miniature-screw lampholders connected in series for across-the-line use or with candelabra- or intermediate-screw lampholders connected in parallel for direct-connection use. These requirements also cover factory-assembled seasonal decorative outfits such as wreaths, stars, light sculptures, crosses, candles or candle sets without lamp shades, products in the shape of, or in resemblance to, Christmas trees with simulated branches and needles, products in the shape of, or in resemblance to, wreaths provided with simulated branches and needles, blow-molded figures or objects, animated figures, tree tops, controllers, tree stands, electric tree poles, and motorized decorative displays. These requirements cover products which are portable and not permanently connected to a power source.
This standard describes the requirements and operational parameters for electrical appliance protectors for use with equipment at normal voltage of 110V, 120V,220V, 240V and a current of up to including 40 A.
This British Standard specifies requirements for the construction dimensions and mechanical and electrical properties of non- armoured polyvinyl chloride (PVC) insulated cables for operation at voltages up to and including 450 V a.c. to earth and 750 V a.c between conductors, intended for electric power lighting and internal wiring.
1.1 The requirements of this standard cover holders and connectors for electric lamps, including incandescent, fluorescent, and other electric-discharge-type lamps, rated as indicated in Clause 6, to be used in accordance with the Canadian Electrical Code (CEC), Part I, C22.1, and the National Electrical Code (NEC), ANSI/NFPA 70. 1.2 These requirements cover screw lampholders, including those intended to be mounted directly on an outlet-box, lampholders for special uses, lampholders for electric signs, and adapters that convert one lampholder size to another.
