Some testing organizations are accredited to perform wind turbine testing to recognized standards and some are not. Test reports from accredited testing organizations such as the National Renewable Energy Laboratory (NREL) will require the minimum level of scrutiny from the SWCC. Testing performed by non-accredited organizations will require a higher level of scrutiny to independently verify the test setup complies with the Standard, the competence of the organization, and the quality of the test reports. Details are available in the SWCC Certification Policy. SWCC has compiled a list of potential test organizations that intend to test small and/or medium wind turbines for the North American market. The list may not be all-inclusive. The list is not an endorsement of any test organization, only an informative list.
