EPA-recognized laboratories test products according to the test methods referenced in ENERGY STAR specifications. In order for EPA-recognized certification bodies (CBs) to certify a product as ENERGY STAR, the test results for that product must come from an EPA-recognized laboratory. EPA provides recognition to laboratories that are either accredited to ISO/IEC 17025 by an EPA-recognized accreditation body (AB) or participate in a CB's witnessed or supervised manufacturers' testing laboratory (W/SMTL) program for the relevant ENERGY STAR test methods. Laboratories may also test products for verification or challenge testing.
- Test products according to the required test methods in the relevant ENERGY STAR specification.
- Cooperate with ongoing audits by ABs, CBs, and EPA.
- Maintain accreditation and keep track of new and revised specifications and test methods.
- Participate in inter-laboratory comparison testing or proficiency testing, when required.
How Accredited Laboratories Apply for EPA Recognition
- Obtain or maintain accreditation to ISO/IEC 17025(link is external) from an EPA-recognized AB for the relevant ENERGY STAR specifications.
- Comply with the Conditions and Criteria for Recognition of Laboratories (PDF, 32 KB).
- Develop separate test procedures for each accredited ENERGY STAR test method.
- Complete and sign the application (PDF, 376 KB)for recognition of laboratories.
- Submit scope of accreditation from an EPA-recognized AB and signed application to Certification@energystar.gov.
- To update recognition, submit an updated or new scope of accreditation, and updated application to Certification@energystar.gov.
First-party laboratories without accreditation should contact an EPA-recognized CB to inquire about enrolling in an W/SMTL program. The steps toward recognition for those programs are similar to the ones listed above.
