Domestic Water Saving Standards Basic Stereotypes At present, domestic sanitary water-saving standards have been basically established. From the perspective of national standards, the flow of water outlets sold in the domestic market should meet the requirements of GB18145-2003 Ceramic Sealing Taps, toilet water consumption. It shall comply with the regulations of GB6952-2005 "Sanitary Ceramics": the regular type (single/double gear) is 9L, the water saving type (single/double) is 6L, and the maximum water consumption of the toilet shall not exceed 1.5. L.
From the standpoint of water efficiency standard of sanitary products produced by sanitary ware companies, the latest standards implemented in the domestic sanitary ware industry are GB25501-2010 â€œWater nozzle water efficiency limit value and water use efficiency gradeâ€ and GB25502-2010 â€œThe limit value of toilet water efficiency and Water efficiency rating.
GB25501-2010 specifies that the water nozzle water use efficiency grade is divided into 1, 2, and 3 levels, the water efficiency limit value is 3 (0.150 L/s), and the water saving evaluation value is 2 (0.125 L/s). After the implementation of this standard, the maximum flow of the spout (excluding the spout, the shower spout, the washing machine spout, and the temperature control spout in the outlet part of the bathtub (bathroom renderings)) under the conditions specified in GB 25501-2010 shall not be greater than 0.150. L / s, otherwise it is unqualified products, flow is not more than 0.125L / s water faucet for the water-saving faucet.
The GB25502-2010 toilet water efficiency is divided into 1, 2, 3, 4, 5 five, water efficiency limit value of 5 (single file water consumption is 9.0L, double block water consumption has 3 evaluation indicators: large Block water consumption is 9.0L, small block water consumption is 6.3L/s, average value is 7.2L/s); water saving evaluation value is 2 (single block water consumption is 5.0L, there are 3 evaluations for double block water consumption Indicator: 5.0L for large block, 3.5L/s for small block, 4.0L/s average). Toilet water consumption is less than 5 requirements for substandard products, not less than 2 requirements for the evaluation of water-saving toilet.
According to the expert from the National Center for Testing and Qualification of Water Drainage and Water Saving Equipment, the evaluation value of the water faucet water-saving is Grade 2 of the water efficiency rating, and the flow rate of the evaluation indicator has been increased from 0.150L/s to 0.125L/s. This requires the manufacturer The internal structure of the spout product should be optimized, and the selection of accessories, especially attachments (bubblers), should be appropriate to meet the requirements of water-saving indicators specified by the water spout water efficiency standards. From the perspective of the current production situation of the company, it is not difficult to meet these standards. The popular brands in the market basically have mature standard production and technical conditions.
Convergence with international standards is a trend When reporters visited the market, they found that most major bathroom brands have almost all water-saving and energy-saving products. Whatâ€™s more, direct promotion of all products in their brands is based on energy saving and water saving. However, when asked carefully about the principles and characteristics of its energy-saving products, most businesses can only ambiguous, or come up with some different "water-saving certification." Obviously, at present, there are many false information and â€œpseudo-products for water savingâ€ in the bathroom market.
In recent years, water quality standards have often been found to be unsatisfactory in spot checks of bathroom products in various markets throughout the country. From an industry perspective, the key is still lack of effective constraints. In the current sanitary ware industry, it is unrealistic to carry out compulsory inspection of water quality standards for all sanitary ware products. At the same time, there is no universal audit standard for â€œwater savingâ€ in the industry. This means that many sanitary companies can obtain a title and certificate of â€œwater-savingâ€ products by looking for a listed company and paying some fees. Because of this, the management of water efficiency standard signs has become crucial.
What can be done now is that, according to GB25501-2010 Water Sprinkler Water Efficiency Value Article 6 â€œDescription of Water Use Efficiency Levelâ€, the manufacturer shall determine the flow rate and rated water use efficiency rating of the product according to the requirements of this standard and the test results. And on the package indicate the flow of the product, rated water efficiency rating, based on the standard number. Prior to the implementation of the â€œAdministrative Measures for Water Efficiency Labellingâ€ of the relevant state agencies, the product identification of the company may be designed on its own, but at least the product flow rate, rated water use efficiency rating, and Standard.
When purchasing, consumers can first refer to the â€œrated water use efficiency rating, flow rate or water consumptionâ€ marked on the product manual or package, and clearly know the flow of the spout, the water consumption of the toilet, and select products with high rated water use efficiency levels. .
With the occurrence of the "lead-containing door" incident in the tap (faucet decoration effect drawing) in July this year, domestic consumers have become more aware of the standard of bathroom products, and the sanitary industry is also interested in directly establishing international standards in the formulation of standards. The convergence of European and American standards, as the current production technology has gradually matured, the realization of the same standards as developed countries in the actual process has also become a reality.
At present, the standard for heavy metal content of water spout products and the IPC-2012 standard for enforcement of plumbing sanitary products are expected to be implemented in the next year. This is also seen as an important symbol of convergence with international standards.
