Must a lab be accredited to all of the test methods for a given lighting specification sub-category to be recognized?

Yes. Every test method is required to be recognized for a given lighting specification or sub-category as outlined in the ENERGY STAR Guide to EPA Laboratory Recognition by Lighting Category. EPA created this document to assist laboratories, accreditation bodies (ABs), and certification bodies (CBs) seeking EPA recognition with identifying the test methods to which a laboratory must be accredited to gain EPA recognition for testing one or more lighting product types.
