Bis Certification For Self-contained drinking water coolers Self-contained drinking water coolers, commonly known as water coolers, offer the convenience of dispensing cold, hot, or room temperature water. With water being essential for our health, ensuring access to clean drinking water is paramount. The Bureau of Indian Standards (BIS) emphasizes safety by requiring ISI mark certification (IS 1475 (Part 1): 2001) and a BIS license for waterfall water coolers. Manufacturers must obtain BIS certification to market their self-contained drinking water coolers confidently, guaranteeing compliance with quality standards and assuring consumers of a safe and healthy hydration option. This regulatory framework safeguards public health while promoting trust and reliability in the market.
