This standard describes the properties of mercury the nature of hazards associated with it and essential information on its storage, handling packing , labelling disposal of waste and personal preventive measures.
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.

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.
