Vacuum Insulation Panels (VIPs) are having difficulty entering the Korean market because there is no Korean standard (KS). The draft international standard (ISO/DIS) 16478 has being developed, and this version is expected to make the final draft international standard (FDIS) until this year and then establish as the International standard. Since the standard is going to be converted to the KS standard, it is absolutely necessary to technologically review for reasonable conformity with the developed standard. It is inappropriate the test method according to ISO/DIS 16478 that takes at least 6 months (180 days) for one product of vacuum insulation panel using fumed silica considering the characteristics of the Korean market. The gas and moisture permeability affects on the thermal conductivity of the aged vacuum insulation panel. The adjusted accelerated condition can establish as a test method that requires about 30 days comparing to 180 days suggested in the ISO/DIS 16478. Through future research, we plan to conduct a technical review of two test methods and results, performed for 30 days under high acceleration conditions (80℃, 70% RH) and 180 days under accelerated conditions (50℃, 70% RH).
