BIS Certified Water Purifiers

The Bureau of Indian Standards, the national organization for standardization and grading in India, offers BIS certification as a mark of guarantee for the quality of its products. A BIS-certified water purifier signifies that it has passed rigorous quality testing and complies with water purification standards as per Indian regulatory guidelines. The ISI mark is another name for the BIS certification mark. The ISI mark provides customers with the assurance that a water purifier is dependable, secure, and of superior quality.

The Purpose of BIS Certification for water purifiers

BIS Certification serves two purposes. First, it assures consumers of the quality and safety of the water purifiers. By adhering to strict standards, BIS certification ensures that water purifiers are efficient, effective, and reliable in removing impurities from water through the process of reverse osmosis. Secondly, BIS certification aids export businesses by providing them with a mark recognized globally. This means that BIS-certified water purifiers can be sold in both domestic and international markets, boosting trade opportunities for manufacturers.

How to Obtain a BIS Certification for water purifiers

To obtain a BIS Certification, the manufacturer of the product must apply to the Bureau to obtain a BIS certification. The examination involves a rigorous process that ensures the products adhere to the water purification standards set by the BIS. The process begins with the producer or manufacturer applying for certification, followed by sample testing by a BIS – approved test laboratory. The Laboratory conducts certain methodical processes such as Reject Water Control Mechanisms, TDS Reduction, Leakage Current Test, and others. If the water purifier meets the specifications and requirements, the manufacturer can proceed with the BIS registration process. This includes providing necessary documentation and the marking of the product with the standard mark of BIS certification. The certification process is regulated by conducted and by the state-approved labs and research bodies, ensuring transparency and fairness in establishing the credibility of the BIS-certified water purifying product.
