This document specifies the properties to be declared by the manufacturer at the time of delivery, as well as some test methods for the determination of these properties.
This document provides limiting values for most of the properties. These limiting values are for specification purposes only. Design values can be derived from these by considering the environmental factors affecting the thermal performance of the product, the influence of the product properties on installation, and the effect of workmanship on the thermal performance.
