Visual Display Units (VDUs) and Video Monitors up to 32 inches under Indian Standard IS 13252 (Part 1) must have their BIS CRS (Compulsory Registration Scheme) certification. It guarantees quality, safety for products, and adherence to Indian laws. Manufacturers have to submit paperwork, test their goods in a BIS-registered lab, and apply via the BIS Manakonline site. Approved, they can brand their goods with the BIS CRS mark. The certification must be renewed and lasts two years. Selling VDUs and monitors in India depends on this mechanism, which guarantees customer safety and regulatory compliance.
