One of those factors is the center-of-panel thermal resistivity. The center-of-panel thermal resistivity is an approximation of the thermal resistivity of the core evacuated region.<\/p>\n<p id=\"s00004\">1.3 This test method is based upon the technology of Test Method C 518 but includes modifications for vacuum panel applications as outlined in this test method.<\/p>\n<p id=\"s00005\">1.4 This test method shall be used in conjunction with Practice C 1045 and Practice C 1058 .<\/p>\n<p id=\"s00006\">1.5 The values stated in SI units are to be regarded as standard.
