16 2. In case that the president of Technology Institute requests test-related materials, the testing/ inspecting laboratory that issued a test report in accordance with the clause 1 shall follow the request as long as there is no specific reason. If the laboratory rejects the request without any reasonable cause, the laboratory may be restricted to conduct a requested test. 3. With respect to verification of submitted documents, whether it complies with the certification criteria shall be verified with the test reports, statement of raw materials supply/production, certificates related to the product, user guides or manuals or products that are submitted by the person who seeks for certification of Eco-label in order to verify that the product complies with relevant criteria. In case of service, it can include performance materials, documentary evidence and photos of the side. However, if it is difficult to verify it only with the submitted documents, tests corresponding to the clause 1 may be added. 4.
