Description

This Standard provides clear and concise requirements for determination and reporting of total R-values and system R-values to promote greater consistency of these calculations within the Australian and New Zealand marketplaces.

Scope

This standard cover:

• a) Standard assumptions for the calculation of system and total thermal resistance of insulation products used in thermal calculations;
• b) A prescriptive calculation methodology for determining the thermal resistance of airspaces with parallel bounding surfaces of varying emissivity;
• c) A range of conversion coefficients for multiple insulation types; and
• d) Prescriptive reporting requirements for demonstrating total R-value and system R-value calculations.
