1.1 These requirements cover ballasts of the resistance, reactance, and electronic (high frequency) types for use with fluorescent lamps involving a potential of 2500 volts or less in accordance with the National Electrical Code, ANSI/NFPA 70.1.2 A fluorescent-lamp ballast may be determined by investigation to be acceptable for use, in a fixtureor other device, with electric-discharge lamps of other than the fluorescent type.1.3 Fluorescent self ballasted lamps and ballast adaptors are evaluated using the Standard forSelf-Ballasted Lamps and Lamp Adapters, UL 1993. The component ballast is evaluated to requirementsin this Standard.1.4 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shockor injury to persons shall be evaluated using appropriate additional component and end-productrequirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
This standard gives general instructions for carrying out microbiological examinations in accordance with specific standards. To help to ensure the validity of the examinations. To ascertain the general techniques used for conducting the examinations are the same in all labs. To help to achieve homogeneous results.
