On April 1, 2003, the World Health Organization began enforcing a standard of 0.01mg/l of lead in drinking water. In accordance with this the Japan Industrial Standards Committee created JISH5120 which specifies 6 types of lead-free bronze. There is also a standard related to the removal of lead from the surface of leaded bronzes through an etching procedure. We provide advice and solutions to our customers in relation to these matters.
