Companies scramble to meet requirements of more lead-free legislation
The Water Quality Assn. (WQA) announced it will offer testing and certification to companies needing to comply with the requirements of a new lead-free law in Louisiana.
The law takes effect Jan. 1, 2012, and requires “not more than 0.2% lead when used with respect to solder and flux, and not more than a weighted average of 0.25% when used with respect to the wetted surfaces of pipes and pipe fittings, plumbing fittings, and fixtures.” Exceptions are made for plumbing not expected to be used for human consumption.
With this law Louisiana joins California, Vermont and Maryland in mandating lead-free plumbing. The Federal Lead Plumbing Law, which takes effect Jan. 1, 2014, is expected to drive more states to implement such laws.
WQA created its lead certification program for companies facing a low-lead law that took effect in California in the beginning of 2010. Under WQA’s process, guided by the NSF/ANSI 372 standard:
• WQA will perform a desktop review of lead content.
• WQA’s laboratory will perform XRF (x-ray fluorescence) scanning on materials that contain lead in their formulation and some materials that are disclosed not to contain lead in their formulation to confirm the exact lead content.
• Digestion will be performed if the results from the XRF scan are higher than the disclosed percentage lead content.
