A weathering test method comprising making active oxygen and light simultaneously act on a test piece, a weathering test method comprising successive and/or alternate steps of making active oxygen and light simultaneously act on a test piece and making at least one of light, oxygen, and water to act on the test piece, and apparatus for carrying out the methods are disclosed. In evaluating weatherability of organic materials, articles made of organic materials or articles coated with organic materials, the methods and apparatus achieve acceleration of deterioration of test pieces to greatly reduce the testing time.
