3 1.0 INTRODUCTION 1.1 General This Standard establishes practices for the generation and interpretation of drawings and related documents at Randtron Antenna Systems (RAS). This Standard basically invokes requirements as set forth in ASME Y Engineering Drawings Practices. To accommodate how design engineering, manufacturing engineering, fabrication, procurement and quality assurance are uniquely implemented at RAS, this Standard includes some level of tailoring of ASME Y Paragraph 3.0 of this Standard includes an ASME Y applicability matrix. This matrix addresses each paragraph of ASME Y and states the level of applicability invoked by this Standard. 1.2 DOD-D-1000 This Standard establishes practices for the preparation of engineering drawings in accordance with Military Specification DOD-D-1000B level 3 (production) requirements. 1.3 Legacy Drawings The requirements as defined in this Standard shall be applicable to all RAS drawing documents from the date of initial release. It is not necessary or advisable to revise legacy drawings generated and released prior to initial release of this Standard. EP-5.0-3
