b'Test Report XC3945/R1Final Issue (Rev C) Thermal transmission properties of 50mm EPS-FR board (SL grade)3CALCULATION OF DECLARED VALUES Declared values of thermal properties may be calculated in accordance with AS/NZS 4859.1:2018 by applying statistical derating factors to achieve 90 % confidence level of a value the median exceeds (for thermal resistance) or falls below (for thermal conductivity). AS/NZS 4859.1:2018 provides that where 10 measurements have been performed, a defined multiplier of 0.44 is applied to the sample standard deviation and is subtracted (in the case of thermal resistance) or added (in the case of thermal conductivity) to the mean value. AS/NZS 4859.1:2018 also imposes rounding requirements on calculated properties.These have been incorporated in results that are presented in Table 3.
