The water nozzle national standard imposes a limit on the precipitation of 17 heavy metals
Lead precipitation per liter of water is not more than 5 micrograms
The General Administration of Quality Supervision, Inspection and Quarantine and the National Standards Committee have issued a new revised “Ceramic Sheet Sealing Water Nozzle†(GB18145-2014) mandatory national standard, which is a mandatory clause for the precipitation of heavy metal, sealing performance, flow rate and life of the nozzle. A strict limit value was imposed on the precipitation of 17 heavy metals. The new standard will be implemented on December 1, 2014.
According to the relevant personages of the National Standards Committee, with the economic development and social progress, the requirements for health and safety of urban and rural residents in China are getting higher and higher. In order to meet the health and safety needs, the National Standards Committee attaches great importance to the problem of excessive lead in water nozzles, and entrusts the National Building Sanitary Ceramics Standardization Technical Committee to organize industry experts, inspection agencies, certification bodies, enterprise representatives, consumer representatives and research institutes to conduct multiple rounds of demonstrations. In-depth discussion, actively revised the "ceramic sheet sealing nozzle" national standard, the standard metal contaminants in the standard to a clear increase in the types of metal contaminants.
China is already the world's largest producer and exporter of faucets. The annual output of the country exceeds 150 million pieces, the annual sales exceed 20 billion yuan, and the output of the largest enterprises is about 20 million pieces. China's ceramic sheet sealing nozzle domestic sales of nearly 300 companies, the vast majority of small private enterprises, mainly concentrated in Guangdong, Fujian, Zhejiang and other coastal areas, accounting for more than 95% of the country's total output.
The new standard imposes heavy metal precipitation, sealing performance, flow, and life as mandatory provisions, and the rest are recommended. According to reports, the sealing performance is the most basic performance requirement of the faucet. It mainly checks whether the faucet leaks water, causing waste of water resources or damage to the user's property. Flow rate is the most important performance of the nozzle. It determines whether the nozzle is water-saving and meets the normal function. The flow is too large to waste water. The flow is too small to meet the normal function. Lifetime is a measure of the faucet life cycle. It is also an important indicator to measure the quality of the faucet. The quality of the faucet components and auxiliary materials will affect the life of the product. By forcing the life of the faucet, the product can be ensured. Meet the normal use function.
For the heavy metal precipitation indicators and limit values ​​that have been widely concerned in the society for some time, the standards respectively stipulate that the precipitation of lead per liter of water is not more than 5 micrograms, and the precipitation limits of the other 16 metals per liter of water are separately specified.
