If the difference is greater than 5% then the uncertainty in the measurements of thermal resistance and conductivity will be greater than 3%. Somefoaminsulationmaterialssuchasphenolic,polyurethane,polyisocyanurateand extrudedpolystyrenecanexhibitthecharacteristicofagingofthematerial,thethermal conductivity increasing with time. Since the previous history of the test material is unknown and no accelerated aging has been performed, these results should without further information be considered as representative of the performance of new material only and actual longer-term in-service thermal conductivity may be higher.7.REFERENCES ASTM C518Standard Test Method for Steady-State Heat Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus.American Society for Testing and Materials, Philadelphia, PA, 2017 REPORT NUMBER:ISSUE DATE:PAGE:DI10856-001-014 May 20185 of 5 branz.nz | 1222 Moonshine Rd, RD1, Porirua 5381, Private Bag 50 908, Porirua 5240, New ZealandPhone +64 4237 1170branz@branz.co.nz'
