HG/T 20637.1-2017 is the English-translated version of 化工装置自控专业工程设计文件的编制规范 自控专业工程设计文件的组成和编制.

HG/T 20637.1-2017 opens the recommended Chinese chemical industry code on the preparation of engineering design documents for instrumentation in chemical plants. Part one sets out what those instrumentation engineering design documents are made up of and how they are to be prepared, so it is the general part on which the rest of the series rests. It is classified as P94 in the Chinese scheme and under 25.040.40 and 71.010 internationally. It quotes HG/T 20573, the companion parts HG/T 20637.2 to HG/T 20637.8, HG/T 20638, HG/T 20639.2 and GB 50493. It takes the place of HG/T 20637.1-1998. Issued on 7 November 2017, it has applied since 1 April 2018.
