Drinking natural mineral water and purified water testing

Packaged drinking water refers to water that is sealed in packaging containers that comply with food safety standards and relevant regulations and can be used for direct drinking. The packaged drinking water includes natural mineral water, purified water, and other types of drinking water. Other types of drinking water include drinking natural spring water, drinking natural water, and other drinking water

Drinking natural mineral water: Water that naturally gushes from deep underground or is collected through drilling, contains a certain amount of minerals, trace elements, or other components, is not contaminated in a certain area, and preventive measures are taken to avoid pollution; Under normal circumstances, its dynamic indicators such as chemical composition, flow rate, and water temperature are relatively stable within the natural cycle fluctuation range

Purified drinking water: refers to water that meets the hygiene standards for drinking water and is prepared by distillation, deionization, ion exchange, reverse osmosis, and other appropriate processing methods. It is sealed in a container and does not contain any additives, and can be consumed directly

Drinking natural spring water: Water that naturally flows out of the ground or is collected through drilling and contains a certain amount of minerals. Its dynamic state (flow rate, water quality, water temperature, water level) is relatively stable, allowing for limited treatment methods such as degassing, aeration, decanting, filtration, ozonation, or ultraviolet disinfection and sterilization. It is sealed in a container without adding any substances and can be directly consumed

Drinking natural water: It is produced from surface water or groundwater (mainly including natural spring water, spring water, mountain spring water, deep lake (reservoir) water, well water, etc.), and only undergoes limited treatment methods such as necessary filtration, ozone treatment, or ultraviolet disinfection and sterilization. It does not contain any chemical additives and can be directly consumed in sealed containers

Introduction to the comprehensive testing items for packaged drinking water:

Color, turbidity, state, taste, odor, conductivity [(25 ± 1) ℃], pH value, chloride (as Cl ˉ Calculation, residual chlorine (free chlorine), carbon tetrachloride, chloroform, label, oxygen consumption (in O), bromate, copper, anionic synthetic detergent, total α Radioactivity, total β Radioactivity, coliform bacteria, Pseudomonas aeruginosa, lead (in Pb), total arsenic (in As), cadmium (in Cd), mercury (in Hg), tin (in Sn), nitrite (in NO), net content, cyanide (in CN), volatile phenols (in phenol), etc. (The testing items are for reference only and can be adjusted based on specific product classification, execution standards, and testing needs.)

Function of testing report:
