MODUK - DEF STAN 59-27: PART 1
Precision Instrument, Rotating, Servocomponents Part 1: General Requirements and Common Tests for Servocomponents
|Publication Date:||1 January 1990|
This Standard relates to the following types of prec~s~on instrument, rotating, servocomponents; synchros, resolvers, and transolvers for use in fire control systems, radar, navigational aids, guided missiles and other similar applications.
This document does not necessarily embrace all the test requirements and/or severities appropriate for every possible military application of servocomponents. It is, in all cases, the responsibility of the user to ensure that the requirements stated in this document are adequate for his intended application.
It gives information on or states the requirements for all those aspects or attributes which are common to the components listed in 1.1, viz:
Related specifications and documents.
Constructional requirements and recommendations.
Testing, inspection and approval procedures.
General conditions of test.
Mechanical, electrical and environmental tests.
The document shall be read in conjunction with the separate appropriate associated Parts, each of which relates to a particular class of component (eg synchros), and with the relevant Supplementary Detail Sheets to each Part, which define the attributes of the individual item. An item is thus fully defined by:
This document, dealing with those aspects, requirements and tests common to the classes of servocomponents, specified in 1.1.
The Part relating to the particular class of component, which details the definitions, marking and performance test requirements specific to that class, and
The relevant Supplementary Detail Sheets to any given Part, which specifies the physical, mechanical and electrical characteristics of the individual items.
This Defence Standard requires that the servocomponents specified in 1.1 having the same type designation shall be physically and functionally interchangeable.
Except for the inclusion of those drawings needed to define physical interchangeability, the Standard does not include drawings governing construction nor, other than in a general sense, does it specify methods of construction or the materials to be used.
