This standards replaces IRE standard 48 IRE 22, SI "standards on Television: Methods of Testing Television Receivers, 1948." At a later date, a standard for color television receivers will be introduced. Reference will be made in that standard to many portions of the present standard which are applicable to color television receivers as well as to monochrome receivers.

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.

The purpose of this procedure is to define uniform acceptable methods for making tests to determine the performance of alternating-current, aircraft type, induction electric motors. The methods in this publication are intended to serve as a standard for both manufacturers and users of aircraft motors. It is intended that the standardizing of test procedures will lead to coincident test data regardless of which party conducts the test. The procedure is applicable to aircraft motors which operate from constant-frequency (nominally 400-cycle-per-second) constant-voltage (nominally 115 volt line to neutral, 3-phase four-wire or 115 volt single-phase) alternating-current aircraft power systems.

This paper focuses on progress in reducing or eliminating exchange restrictions that has been substantial and has been made on a wide front; retrogressions have been comparatively few. The beneficial effects of the widening scope of currency convertibility have been felt in many areas, and the evolution toward freer, more orderly, and less discriminatory trade and payments has been strongly supported by a high level of economic activity, expanding international trade, and the general maintenance of monetary stability. Recent developments in trade and payments have not merely reduced the scope of restrictions; they have also changed the nature of these restrictions. Of key importance was the introduction of external convertibility by several countries at the end of 1958. Quotations for externally convertible currencies in exchange markets throughout the world have shown only minor fluctuations in the past twelve months. Most Western European currencies have generally been strong in terms of the US dollar.
