ISI Mark for Domestic Water Heaters for use with LPG

To receive a BIS license for LPG-powered domestic water heaters, producers must follow IS 15558 under the ISI Mark Certification Scheme. The process entails applying through the Manak Online Portal, submitting papers, undergoing a factory inspection, and having product samples tested at a BIS-approved laboratory. If the product passes safety and performance standards, BIS provides the authorization to use the ISI mark. Regular audits and renewals are required to ensure ongoing compliance. The fees include an application cost, a license price, and a marking charge. BIS certification guarantees product quality, safety, and consumer trust in the marketplace.
