Description:
The ANSI/NSF 61, Section 8 standard is intended to protect the public from in-line brass plumbing products that might leach excessive levels of lead to potable water. Experiments were conducted to examine the practical rigor of this test. Contrary to expectations, the test was not highly rigorous with respect to likely lead release into tap water. Rather, it was determined that small devices made of pure lead can easily pass the leaching protocol. Reforms are needed to help prevent such unacceptable outcomes in the future. Brass devices passing the test can cumulatively add to lead levels at the tap in residences, schools and other buildings.
