NSF International (www.nsf.org) recently announced
that it has expanded its plastics-conduit certification program to include high-density
polyethylene (HDPE) telecommunications duct. The new certification is based on F
2160-01, the new American Society of Testing and Materials (ASTM) Standard
Specifications for Solid Wall High Density Polyethylene Conduit Based on Controlled
Outside Diameter.
ASTM F 2160-01 provides testing protocols and criteria for evaluating the performance
of HDPE telecommunications duct.
"Last year, we expanded our plastics piping certification program to include electrical
safety certification of HDPE and PVC conduit to the applicable UL and NEMA
standards," said Mark Jost, vice president of NSF certification. "We're pleased to provide
yet another service to our current and future plastic piping customers, enabling them to
receive certification to the new telecommunications duct standard." Certified products
bear the NSF mark, and are listed in the NSF listing books and on the NSF Web site.
