This document is the primary American National Standard on application of the metric system. It emphasizes use of the International System of units (SI), which is the modern, internationally accepted metric system. It includes information on SI, a limited list of units recognized for use with SI, an...

Guidance on basic qualification principles and appropriate methods of demonstrating the qualification of equipment used in nuclear facilities is provided in this standard. The principles, methods, and procedures described are intended to be used for qualifying equipment.

This standard describes the International System of Units (SI), the modern version of the metric system. It includes listings of the base units, supplementary units, and units derived therefrom. Guidance is provided on application of the SI prefixes, other units in use with SI (including units accep...

The standardisation of methods of testing radio telegraph transmitters is considered. The classification of tests to be performed is discussed, and specific methods of measuring power output, spurious transmitter output, frequency stability, carrier hum, and keying characteristics are given.<>

This recommended practice covers definitions of terms, controlled test conditions, test apparatus, test methods and data presentation, all of which form the basis for establishing the energy levels of spurious emissions of mobile communication transmitters designed to generate frequency-modulated (F...
