Press Releases

EPA Recognizes Rhein Tech Laboratories, Inc. as Third-Party Testing Laboratory for ENERGY STAR® 4/20/2011 Herndon, Virginia

Testing and certification organization Rhein Tech Laboratories, Inc. has received recognition from the U.S. Environmental Protection Agency (EPA) as a third-party testing laboratory under the enhanced ENERGY STAR® program. The EPA recognition establishes Rhein Tech as an independent third-party eligible to test products to ENERGY STAR energy efficiency requirements. The EPA began modifications to the well-established ENERGY STAR program early in 2010. The changes became effective January 1, 2011 and are intended to strengthen the credentials behind the familiar ENERGY STAR mark as a sign of energy efficient product design.

The most significant change is that the voluntary program is no longer based on a self-declaration process, but instead requires that qualification tests be performed by an EPA-recognized laboratory. Also, the practice that allowed a company up to one year after market entry to list a product with the EPA ENERGY STAR Program is no longer accepted. Under the revised program, each product must be tested, certified and listed with the EPA ENERGY STAR Program prior to its entry into the marketplace. In addition to the mandated testing , the EPA intends to implement a verification program in 2011.

This verification program requires ENERGY STAR Partners, typically the brand name holders, to allow for inspection of 10% of their certified products in the marketplace to be sampled by ENERGY STAR Certification Bodies for testing. The certified product samples for the required verification tests have to be purchased off-the-shelf in the markets where the products are sold. The EPA recognition of Rhein Tech as a third-party energy testing laboratory covers a broad range of products. Rhein Tech offers testing for audio/video, battery chargers, computers, displays, imaging equipment, set-top boxes, telephony, and televisions for the ENERGY STAR program.
