1. Scope and Introduction
1.1 This Standard is intended to cover the field of technical drawing practice. It applies primarily to end-product drawings, which usually consist of detail drawings, and assembly or subassembly drawings, but is not intended to fully cover other supplementary drawings such as check lists, schematic diagrams, electrical wiring…
