INTRODUCTION
This Test Procedure is a compilation of recommended rate gyro test procedures derived from those currently in use, including test conditions to be considered. In some cases alternate methods for measuring a performance characteristic have been included. In selecting among the alternates, attention should be paid to the intended application of the gyro, available test facilities, and the standard methods in use by the test facility. This document is intended to be n guide in the preparation of Section 4 of a specification that follows the format of IEEE Standards Publication No. 292, Specification Format for Single-Degree-of-Freedom Spring-Restrained Rate Gyros. The intent is for the specification writer to extract the applicable test conditions and equipment from Section 3 of this document for inclusion in the paragraphs concerning test conditions and equipment corresponding to paragraph 4.5 of the Specification Format. Similarly, it is intended that the writer extract the applicable test procedures from Section 4 of this Procedure for inclusion in the paragraphs concerning test procedures, corresponding to the paragraphs listed under paragraph 4.6 of the Specification Format. This Test Procedure can also be used as a guide in the preparation of a rate gyro test specification, but would require reorganization into the proper Specification Format.
Blanks have been used in this document for two distinct purposes. One purpose is to provide for selection of specific values of test parameters and their tolerances. Other blanks are to be filled in with the number of the applicable paragraph from Requirements Section 3 of the specification being written.
Aerospace Industries Association EETC Report No. 5 (Revision A), "Standard Gyro Terminology"* has been utilized in the preparation of this Test Procedure. Although this Procedure is limited to electrically energized single-degree-of-freedom spring-restrained rate gyros, it can be used as a guide in the preparation of Test Procedures for other types of rate gyros.
