CuraFlo’s CuraPoxy LS Coating First to Earn NSF International Certification to American Society for Testing and Materials’ Performance Standard (ASTM F2831) in addition to NSF/ANSI 61

ANN ARBOR, Mich. and MESA, Ariz. — NSF International, a global independent organization that writes public health standards, and tests and certifies products for the water, food, health science and consumer goods industries, now offers dual certification to ASTM 2831, the American Society for Testing and Materials’ (ASTM) performance standard for epoxy coatings used to rehabilitate pressurized piping systems, as well as NSF/ANSI 61, the nationally recognized health effects standard for all devices, components and materials which contact drinking water. Pipe rehabilitation using a certified epoxy coating saves municipalities, building operators, plumbers and homeowners the cost, time and disruption associated with pipe replacement.

In addition to its NSF/ANSI 61 certification, CuraFlo’s CuraPoxy LS Coating is the first epoxy coating NSF International has certified to ASTM 2831. Certification to both health effects and performance standards provides plumbers, contractors and municipal water treatment and distribution facilities with assurance that CuraFlo’s CuraPoxy LS Coating can effectively coat, seal and rehabilitate pipes without compromising water quality.

NSF certification to ASTM F2831: Standard Practice for Internal Non Structural Epoxy Barrier Coating Material Used In Rehabilitation of Metallic Pressurized Piping Systems verifies that CuraFlo’s CuraPoxy LS Coating meets the minimum durability (resistance to corrosion), strength, adhesion and immersion performance criteria for use in rehabilitating pressurized piping systems. NSF engineers tested CuraPoxy LS Coating to the manufacturer’s instructions for coating thickness and curing time to confirm testing matches field use. Some of the key performance criteria set forth in the standard includes:

  • A pull-off strength test to verify that the minimum pull-force without loss of coating adhesion on metallic surfaces is at least 2500 psi
  • An immersion test to confirm there is no blistering, peeling or disbondment of the epoxy barrier coating
  • An adhesion test to make sure the adhesion of the coating to the piping material is within specifications

CuraFlo’s CuraPoxy LS Coating also earned certification to NSF/ANSI Standard 61: Drinking Water System Components -- Health Effects in 2012. To earn certification to NSF/ANSI 61, CuraFlo’s CuraPoxy LS Coating was subjected to toxicological and chemical evaluation by NSF scientists under various conditions to verify the product did not leach harmful contaminants into drinking water. NSF auditors also inspected Curaflo’s Mesa, Arizona manufacturing facility to verify product formulations, suppliers, and quality assurance/quality control records and that only authorized ingredients were used to manufacture the product. NSF will conduct annual unannounced facility audits and product re-testing to verify CuraFlo’s continued compliance with the requirements of both the NSF and ASTM standards.

“Epoxy coatings are an important tool for maintaining our water distribution infrastructure as they provide an alternative that enables pipes to be rehabilitated instead of replaced. This offers an economical alternative to homeowners and municipal water treatment and distribution facilities,” said Nasrin Kashefi, General Manager of NSF International Plastics and Mechanical Plumbing Certification Programs. “As the first to earn NSF certification to both performance and health effects standards, CuraFlo is providing municipalities, plumbers and contractors with a very valuable pipe rehabilitation product that meets the highest standards for performance, health and safety.”

“CuraFlo has focused its efforts on providing real solutions to multi-tenant housing, schools, universities and other institutions that need to restore failing pipes instead of replacing them. Our research led us to the development of the CuraPoxy LS Coating and now that it has earned both ASTM F2831 and NSF/ANSI 61 certification, users can be confident in its safety for restoring pipes that reach temperatures as high as 180° F,” said Brian LeMaire, President of CuraFlo.

For earning certification, CuraFlo is authorized to use the NSF mark on CuraPoxy LS Coating product packaging and marketing materials, a signal to buyers and regulators that the product has passed the highest standard for health and safety.  This product also appears in NSF’s online listings.

About NSF International: NSF International is an independent global organization that writes standards, and tests and certifies products for the food, water and consumer goods industries, to minimize adverse health effects and protect the environment (nsf.org). Founded in 1944, NSF is committed to protecting human health and safety worldwide.

NSF International's Water Programs require extensive product testing and unannounced audits of production facilities to verify that water treatment products meet the design, material and performance requirements. NSF International is accredited by the American National Standards Institute (ANSI). NSF led the development of the American National Standards for all materials and products that treat or come in contact with drinking water. In 1990, the U.S. EPA replaced its own drinking water product advisory program with these NSF standards. Today, all major plumbing codes require certification to NSF standards for pipes and plumbing components in commercial and residential buildings.

Additional NSF International services include management systems certifications delivered through NSF International Strategic Registrations (NSF-ISR); food safety and quality programs through the NSF Food Safety Division; pharmaceutical, medical device and nutritional supplement auditing and certification through the NSF Health Sciences Division; sustainability services through NSF Sustainability; and NSF Education and Training programs.
