1 Scope 1.1 This Standard specifies photometric performance requirements for cobra-head-style luminaires that are used for roadway lighting applications and that use 70 to 400 W high-pressure sodium (HPS) lamps. Note: Future editions of this Standard might include other light sources such as metal halide and LED lamps. 1.2 This Standard is based on (a) average luminance, luminance uniformity…

Scope 1.1 This Standard applies to factory-made automatic icemakers with a capacity not exceeding 1814 kg/d, measured at standard rating conditions. These machines produce cube, flake, crushed, or fragmented ice in batches or in a continuous process. They are electrically operated and are designed for a 60 Hz operating current with nominal nameplate voltage. 1.2 This Standard applies to…

1.1 This Standard provides the requirements and test methods for air barrier materials used in building applications. 1.2 The test method involves measuring the airflow through representative samples of the material for a range of differential pressures, and calculating an assigned air leakage characteristic of the material at a reference pressure difference (?P) of 75 Pa. The test methods…
