New standard for low-lead plumbing products
NSF International’s new standard affects products that come in contact with drinking water, including faucets.
NSF International has developed a new compositional standard for products that come in contact with drinking water, including faucets. The new requirements are incorporated into the NSF/ANSI American National Standard for Drinking Water Products and are designed to help protect the public from exposure to lead.
Annex G%%MDASSML%%Weighted Average Lead Content Evaluation Procedure to a 0.25 Percent Lead Requirement allows manufacturers to demonstrate compliance to recently enacted California legislation that limits the weighted average of lead content in plumbing products that come in contact with drinking water to 0.25%. The annex was recently incorporated into NSF/ANSI Standard 61: Drinking Water System Components--Health Effects, a standard that includes procedures to evaluate products that come in contact with drinking water and to screen out those products that could contribute excessive levels of contaminants into drinking water.
Products covered in the standard include: pipes and related products; protective and barrier materials (including cements/coatings); joining and sealing materials (including gaskets, adhesives, lubricants); process media (including carbon, sand, zeolite, ion exchange media); mechanical devices (including water meters, in-line valves, filters, process equipment); mechanical plumbing devices (faucets, drinking fountains, and components); and potable water materials (non-metallic materials)

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
