b'Test Report XC3945/R2Final Issue Thermal transmission properties of 200mm EPS-FR board (SL grade)The measurements have been performed using a heat flow meter apparatus and are in general accordance with ASTM C 518-21 Standard Test Method for Steady-State Thermal Transmission Properties by Means of the Heat Flow Meter Apparatus.This is one of the allowable test methods for the measurement of thermally insulating materials for compliance with AS/NZS 4859.1:2018Thermal Insulation Materials for BuildingsPart 1:General criteria and technical provisions.However, compliance with AS/NZS 4859.1:2018 also requires measurement of 10 specimens of a single product and the derivation of declared values of thermal properties which take specimen variability,agingandtemperatureintoaccount.Thisreportdescribessuchaderivationin compliance with AS/NZS 4859.1:2018. The CSIRO laboratory has accreditation for thermal measurements in Australia through NATA, the National Association of Testing Laboratories.Accreditation also extends to other countries through mutualrecognitionarrangementswiththeiraccreditationbodies,includingIANZ,International Accreditation New Zealand.1BACKGROUND TO MEASUREMENTS 1.1Specimen Description and Identification This report relates to measurements of the thermal properties of 200mm EPS-FR board (SL grade).Test results apply only to the specific items tested. The test specimens were described as in Table 1 above.The specimens were also given laboratory Specimen ID numbers which are indicated on the following pages.Product thickness was nominated as 200mm. Appendix A of this report provides images of the specimens. CSIRO 2023Commercial-in-Confidencepage 4 of 9 Copying or alteration of this report without written authorisation from CSIRO is forbidden.
