Below is picture collection of toilet certifications.

Toilet certification

There are ten-ring certification, water-saving and other bathroom certifications in China. And foreign countries are no exception, and the standards for manufacturing inspection are even stricter. Different foreign markets and different countries have different standards for the same category of products. While generally they are higher than the national standard. For example, for household faucets, the American LF standard requires the use of low-lead copper materials with a lead content of less than 0.25% as the base material. The national standard requires that the lead content of ordinary H59 brass is ≤0.5%.

China toilet certification

It will help improve the water-saving efficiency of households and public facilities, and thereby achieve the goal of protecting water resources and reducing waste. The products involved are energy efficiency certifications for toilets, urinals, bathroom faucets, and showerheads.
