The official documents that decide how CRS products are grouped, tested and registered, and the deadlines for revised standards, with a plain-English summary of each and a copy of the PDF.
Registration under BIS's Compulsory Registration Scheme (CRS) is governed by MeitY's Compulsory Registration Order and by guidance documents that BIS and MeitY publish on crsbis.in. The documents below are the ones we use most when planning a CRS registration. They set how many models one test can cover, which products are in scope, how IT and audio-video products move to IS/IEC 62368-1:2023, and the deadlines when a product's Indian Standard is revised.
Every document is official. The summaries are ours. Where a document has been replaced or its deadline extended by a later circular, we say so and link to the newer one.
