GB 17323-1998Bottled purified water for drinking (English PDF)

Foreword

This Standard is a product standard for bottled purified water for drinking. Its definition, scope all refer to Bottled Water, a modified standard which was issued by United States Food and Drug Administration (FDA) in 1993. The test method of "conductivity" is listed in Annex A of this Standard. This Standard was proposed by China Light Industry Association. This Standard shall be under the jurisdiction of China National Food Fermentation Standardization Center. The drafting organizations of this Standard. China Institute of Food and Fermentation Industries, Guangzhou Station of China Light Industry Association of Quality Supervision and Inspection, Shenzhen Yi Bao Food & Beverage Co., Ltd., Zhaoqing Dinghu Steamed Solid Water Limited, Shenzhen King Tin Food & Beverage Co., Ltd., Guangdong Jianlibao Beverage Factory. Main drafters of this Standard. Xu Qingqu, Zhou Damin, Wang Zhihui, Wu Musheng, Zhou Jingliang, Deng Ruiwen. This Standard shall be interpreted by China National Food Fermentation Standardization Center. Bottled purified water for drinking

1 Scope

China's mandatory national standard for bottled purified drinking water. Purified water is defined by its process rather than its source: mains or ground water put through distillation, deionisation, reverse osmosis or an equivalent treatment that removes essentially everything, so the product is water and nothing else. That distinguishes it in law from natural mineral water, which is defined by its source and its dissolved content and may not be treated in the same way. The requirements follow the definition. Conductivity is the operative test, because it measures directly what the process was supposed to achieve. Around it sit the microbiological limits, which matter more than they might seem: purified water has no residual disinfectant and no competing flora, so a contamination that enters at bottling grows unopposed. The standard specifies the requirements, the test methods, the inspection rules and the labelling.

This Standard specifies technical requirements, test methods, inspection rules and marks, packaging, transport, storage requirements for bottled purified water for drinking. It is applicable to the product defined in Clause 3 of this Standard.
