Approved Lab Accreditation and Recognition
For Labs Accredited by NVLAP:
LED Lighting Facts accepts LM-79 reports from testing laboratories that meet the requirements described below. At this time, the NIST NVLAP LM-79 accreditation process is known to fulfill all of the requirements, including proficiency testing and handbooks describing lighting testing accreditation processes. A testing laboratory accredited to LM-79 through the complete NVLAP process needs to submit the following documentation to become an LED Lighting Facts Approved Lab Partner:
A document proving the laboratory’s accreditation, including the subsections of LM-79 testing covered by the accreditation and the effective and expiration dates of the accreditation.
For Labs Accredited by other Accreditation Bodies:
A testing laboratory accredited for LM-79 testing by an accreditation body other than NVLAP must meet the following requirements:
- The chosen accreditation body must be listed on the LED Lighting Facts Approved Labs web page (see the next section for details).
- The testing laboratory must submit a document proving the laboratory’s accreditation, including the subsections of LM-79 testing covered by the accreditation and the effective and expiration dates of the accreditation.
- The testing laboratory must submit proof that proficiency testing has been completed through the NIST LM-79 Measurement Assurance Program (M.A.P.) service. Effective and expiration dates of proficiency testing must be detailed.
Because of the challenges involved with maintaining measurement traceability for a wide range of SSL products and the potential for measurement uncertainty in SSL testing in general, the accreditation must include or be accompanied by proof of proficiency testing (addressing challenges such as particular spectral distributions, remote phosphors, particular intensity distributions, and particular electrical characteristics of samples). As defined in ISO/IEC Guide 43 on proficiency testing, the accreditation process for LM-79 must include periodic repetition and revalidation of proficiency testing (through a documented and regularly scheduled round-robin testing and verification process). LED Lighting Facts will recognize proficiency testing fulfilled through the LM-79 M.A.P. service available from NIST.
Recognition of Other Accreditation Bodies
LED Lighting Facts recognizes LM-79 accreditation granted by bodies other than NVLAP, provided the accreditation bodies meet the following requirements:
- The accreditation body must have a Mutual Recognition Arrangement (MRA) in place with international oversight traceable to the International Laboratory Accreditation Cooperation (ILAC). Proof of this agreement must be submitted to LED Lighting Facts.
- A document describing the LM-79 accreditation process must be published or provided by the accreditation body.
- A document describing the experience and competence of the quality assessor teams for LM-79 accreditation with regard to absolute photometry and SSL testing must be provided. This includes competencies listed in section 2.2.3 of the ILAC Guidelines on Qualifications and Competence of Assessors and Technical Experts, articles 126.96.36.199 and 188.8.131.52 concerning estimation of measurement uncertainties and analysis of proficiency testing needs and results.
LED Lighting Facts lists additional recognized LM-79 accreditation bodies on its Approved Labs web page. Accreditation bodies wishing to be listed must submit documentation of the items above to email@example.com. The testing laboratory may submit this information on behalf of the accreditation body. The LED Lighting Facts team and DOE SSL program staff will review the documentation and make a determination about whether the accreditation body meets the recognition requirements before listing it on the Approved Labs List.
In keeping with past DOE guidance for the ENERGY STAR solid-state lighting program, LED Lighting Facts will accept ISTMT test reports from laboratories that meet any of the following requirements:
- An Occupational Safety and Health Administration (OSHA) Nationally Recognized Testing Laboratory (NRTL). For a list of laboratories, visit www.osha.gov/dts/otpca/nrtl.
- Approved through an OSHA NRTL data acceptance program or OSHA Satellite Notification and Acceptance Program (SNAP).
- Accredited for ANSI/UL 1598 or CSA C22.2 No. 250.0-08, including Sections 19.7, 19.10-16, by an accreditation organization that is an ILAC-MRA Signatory.
IESNA LM-80 Approved Method for Measuring Lumen Maintenance of LED Light Sources defines the test procedure for obtaining lumen maintenance data for LED light sources. An LM-80 report must come from a laboratory accredited for LM-80 testing through NIST’s NVLAP program or a laboratory accredited for LM-80 testing through an accreditation body that is an International Laboratory Accreditation Cooperation (ILAC) Mutual Recognition Arrangement (MRA) signatory. For more information about ILAC MRA signatories, visit www.ilac.org/ilacarrangement.html.
Upon signing the pledge, a laboratory must submit to firstname.lastname@example.org a document proving accreditation or recognition, including the effective and expiration dates, which will be reviewed by LED Lighting Facts. Approved Lab Partners are expected to submit renewed accreditations and certificates as they expire. Failure to keep accreditations and certificates up to date will result in removal from the LED Lighting Facts Approved Labs List.
