The purpose of this procedure to define uniform acceptable test methods for determining the performance and other characteristics of aircraft alternating-current generators. Rotating electric equipment for aircraft is subjected to requirements and operating conditions not normally encountered by commercial generators. For example, conditions of temperature, altitude, humidity, and vibration vary over much wider ranges. Aircraft requirements dictate minimum weight, and yet utmost reliability is essential. Weight reduction is generally achieved by sacrifice of life expectancy commensurate with aircraft practices. The necessity for accurate design requires that direct measurements to insure reliability and adequate life be an important part of this test procedure. It is recognized that there may be acceptable methods of making tests other than those described. Such other methods may be considered as alternative procedures accepted by agreement between interested parties. The tests outlined herein are not necessarily complete for any specific generator; and likewise the requirements in each case will determine the number of tests to be made.

These marine recommendations are intended to serve as a guide for the selection and installation of equipment on merchant vessels with electric apparatus for lighting, signaling, communication, power, and propulsion. The recommendations define what are considered good present-day engineering practices with reference to the safety of the personnel and of the ship itself as well as reliability and durability of the apparatus. It is recognized that changes and improvements in shipboard requirements may develop which are not specifically covered herein; such changes, if incorporated in the design, should be equal to the safety and reliability levels defined herein and generally in accord with the text of these standards. Specific IEEE standards are referenced in the text. Other IEEE standards should be followed to the extent applicable. Attention is directed to the fact that regulations for electric installations on shipboard are promulgated by Governmental Regulatory Agencies, the Intergovernmental Maritime Consultative Organization, and Classification Societies. Such regulations have been given due consideration in these recommendations, but they are areas where differences are expressed. Reference should always be made to those regulations which may be applicable to the design.

This standard sets forth the requirements for installation, inspection, and testing of Class I and Class I E electric power, instrumentation, and control equipment and systems during the construction phase of a nuclear power generating station. These requirements are intended to assure that only materials and equipment of acceptable quality are incorporated into the plant, that quality is maintained and quality workmanship prevails throughout the construction process, and that completed installations c o n f o rm to specified requirements, so as to promote public safety, prevent accidents and mitigate the consequences of accidents if they occur, and provide a high degree o f plant reliability. 1.1.1 In addition to the Class I and Class I E systems, the requirements also apply to the following auxiliary equipment that are a part thereof.
