Water is the source of life and plays an important role in social and economic development. The water quality testing is an important means of ensuring the water quality.
The quality of domestic drinking water is related to the health of residents so that the national health authorities have issued strict laws and regulations to strengthen the management of the quality of domestic drinking water, in order to guarantee the hygienic security of domestic drinking water. The water quality sampling point, inspection item and monitoring frequency of all kinds of water supply facilities, especially the secondary water supply facilities are specified in various laws and regulations.
With its professional qualifications, sophisticated equipment and advanced technology, we (Attestation of Global Compliance) is able to carry out the specialized tests to mineral water, purified water and other types of water, in accordance with various standards related to the drinking water.
On July 1, 2007, the Standardization Administration of China and the Ministry of Health jointly issued a mandatory national standard, i.e., "Standards for Drinking Water Quality" (GB5749-2006) and other 13 national standards related to sanitary inspection of domestic drinking water.
On October 1, 2009, "Standard for Natural Mineral Waters" (GB8537-2008) was officially implemented.
