BIS Certification Consultancy for Self-Contained Drinking Water Coolers | IS 1475 (Part 1):2001 | ISI Mark & Testing Support – Qualitance India

Introduction

Self-contained drinking water coolers are widely used in offices, schools, hospitals, factories, commercial buildings, hotels and public facilities. Manufacturers and importers supplying drinking water coolers in India must understand the applicable BIS certification requirements, product testing procedures and quality-control obligations. The original standard for this product was IS 1475 (Part 1):2001 — Self-Contained Drinking Water Coolers: Energy Consumption and Performance. However, BIS revised this standard to IS 1475:2024 — Drinking Water Coolers. The revised standard's implementation deadline was 12 February 2025. The applicable Quality Control Order (QCO) requires covered drinking water coolers to conform to the relevant Indian Standard and bear the BIS Standard Mark under a valid licence. Therefore, manufacturers seeking certification should prepare against the current applicable requirements rather than rely solely on the earlier 2001 edition. Qualitance India provides BIS certification consultancy, product-scope assessment, documentation support, product testing coordination and factory inspection preparation for manufacturers of self-contained drinking water coolers.

1. What Is IS 1475 for Drinking Water Coolers?

IS 1475 is the Indian Standard applicable to drinking water coolers. The earlier edition, IS 1475 (Part 1):2001, covered energy consumption and performance. It was revised and published as IS 1475:2024, titled Drinking Water Coolers. The revised standard and its BIS Product Manual address important aspects of product construction, cooling performance, energy consumption, storage capacity and electrical safety. Key areas include:

Classification of drinking water coolers.
Construction and components.
Materials used in the product.
Cooling capacity and operating conditions.
Pull-down performance.
Maximum power consumption.
Annual energy consumption.
Water storage capacity, where applicable.
