To enhance the possibility of repeatability of tests, maintain and calibrate the apparatus as described in Appendices A and B. Appendix A contains maintenance and calibration instructions. Appendix B describes the use of reference materials which may assist in determining the performance of the apparatus, and interpreting exposure results when compared to previous tests.
Unless otherwise specified, test specimens shall be 75 X 150 mm (3 X 6 inches), with a maximum thickness of 25 mm (1 inch). For specimens over 25 mm (1 inch) thick, formed or configured specimens, and large components, specific instructions must be obtained from the responsible material engineer of the different automotive manufacturers or automotive suppliers.
Replicate specimens are desirable to provide a record of the changes when they are exposed for different radiant exposure levels. An unexposed specimen should be saved for visual comparison with the exposed specimen. Neither repeatability (precision of multiple determinations at one site) nor reproducibilit (precision of multiple determinations at different sites) have been established. Therefore, it is inappropriate to compare results from different sites or results obtained at different times at the same site. It is strongly recommended that a control material having a known history be exposed simultaneously with test specimens if it is desirable to compare results obtained at different times and/or sites.
