Circular 12/2019/TT-BKHCN stipulates the criteria for determining water-saving products and equipment issued by the Ministry of Science and Technology on November 15, 2019.
Products and water-using devices deemed to be water-efficient must meet the following criteria:
- The product or device's features ensure the intended usage is consistent with the standards declared applicable to the product or device;- The water use efficiency grade conforms to the corresponding national standards published by the Ministry of Science and Technology for water-efficient products and devices.
In addition to the above criteria, the Ministry of Science and Technology classifies the water use efficiency of water-efficient products and devices into three levels in ascending order to reflect the degree of water savings. Specifically, level 1 represents the lowest water use efficiency corresponding to the least water savings, and level 3 represents the highest water use efficiency corresponding to the most water savings.
For detailed content, see Circular 12/2019/TT-BKHCN effective from January 1, 2020.
