    PREFACE

    In our efforts to achieve self reliance in vital areas of defence preparedness , the equipment developed and produced has to meet the most stringent quality standards and should fully meet the operational requirements laid down by the users . This calls for the relevant equipment specification, which is a governing document for production and supply of the equipment for the users and shall always invoke the tests and conditions laid down in this specification, to provide a common basis for comparison for performance of various electronic and electrical equipment under Service environments. Keeping in view the stringent quality and operational requirements of the users, the Joint Services Specification No. 55555 on Environmental Test Methods for Electronic and Electrical Equipment (JSS 55555) was prepared in 1979 which was later revised in 1988. Considerable experience has been gained over the years since 1988 and this has necessitated revision of the existing JSS 55555 . This document JSS 55555 on Environmental Test Methods for Electronic and Electrical Equipment has been reprinted with the various amendments incorporated . In this revised JSS 55555, major changes like introduction of modified L-2 Table and recasting of five Tables pertaining to Naval and Naval Air Services, have been incorporated. In addition Test No. 8 on Corrosion (Alkaline), Test No. 30 on Temperature, Humidity, Vibration and Altitude and Test No. 31 on Vibro Acoustic, Temperature have been added in this revised document.

    SECTION 1

    GENERAL INFORMATION 1. SCOPE 1.1 This specification describes standard procedures and conditions for Environmental tests for Service Electronic and Electrical Equipment (except those associated with explosives and guided missiles). 1.2 This specification includes environmental conditions obtainable in the laboratory, such that if an item is exposed to these conditions and continues to operate in a satisfactory manner, a high degree of confidence will have been established that the item could survive the field environment during its expected operational and storage life. The tests described herein are not to be interpreted as an exact and conclusive representation of actual operational and storage conditions. It is also the purpose of this document to standardize environmental tests in order to obtain, as much as possible, reproducible test results. 1.3 The tests specified herein are intended to serve the need for predetermining the potential causes of failure of equipment under operational and storage environments. In some of the tests, t
