Abstract

<u>Purpose</u> The purpose of this document is to provide a standard for specifying bonded resistance strain gages. In accomplishing the purpose of this document, it is necessary to: <br>(a) Establish standard nomenclature for describing bonded resistance strain gages in this specification. <br>(b) Prescribe the minimum amount and kind of qualification and quality control tests to be performed by strain gage manufacturers, and to standardize the manner in which the data are furnished. <br>(c) Define the minimum capabilities of the test equipment to be used to perform the qualification and quality control tests. <br>(d) Set forth the methods to be used to perform the qualifications and quality control tests. <br>(e) Establish criteria for classification of strain gages with respect to performance. <br>(f) Classify strain gages with respect to performance.<b><u>Intended Use:</u></b> The specifications in this document provide a means for comparing and selecting strain gages on a preliminary basis. This document will require manufacturers to furnish that minimum information which the user or purchaser needs to make a selection for a particular application. This document is not intended to provide information to be used for the calibration of a specific strain gage installation, except in the cases of gage factor, resistance, and the thermal output coefficient. This document will also provide the purchaser and the manufacturer with a standard means of specifying strain gage characteristics.<br>
