ISO 16546:2020

This document specifies the equipment and test method for determining the effects of successive cycling from dry conditions at −20 °C to wet conditions at 20 °C on the mechanical properties and moisture content of thermal insulating products. This document is intended to simulate the freeze?thaw effects on thermal insulating products which are frequently exposed to water and low temperature conditions, e.g. inverted roofs and unprotected ground insulation.
