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.

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 specifies the minimum requirements for VHF transmitters and receivers fitted with a 50 Ω external antenna socket or connector for use on board ships and operating in the bands between 156 and 174 MHz allocated to the maritime mobile service by the International Telecommunications Union Radio Regulations (Radio Regulations, Appendices 18 and 19).

This standard specifies the requirements for radio transmitters and receivers for the fixed and land mobile services in bands allocated within 27.41 to 960 MHz range.

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.

These requirements cover products which are molded of insulating material and are intended to cover the outlet slots of receptacles having 1-15R and 5-15R configurations in accordance with Wiring Devices-Dimensional Specifications, ANSI/NEMA WD6.1.2 These requirements do not cover insulating devices provided to cover the unused outlets of a multi-outlet cord connector employed on a general-use cord set. The requirements for these devices are contained in the Standard for Cord Sets and Power-Supply Cords, UL 817. 1.3 These requirements do not cover receptacle closures provided as part of a flush device cover plate. These devices are covered by the requirements in the Standard for Metallic Outlet Boxes, UL 514A, or in the Standard for Nonmetallic Outlet Boxes, Flush-Mounted Boxes, and Covers, UL 514C.
