ISO 16957:2016 describes a method of measuring the thermal conductivity (diffusivity) of a wet porous building material and a method of evaluating the measurement uncertainty. While ISO 10051 is the current International Standard, based on a steady-state method, ISO 16957:2016 proposes a method that makes use of a non-steady-state method which uses a small temperature change with a short period as an input. Along with the measurement, an evaluation of the measurement uncertainty is described, which makes possible a simple and practical measuring method. ISO 16957:2016 intends to measure the apparent (effective) thermal conductivity, including latent heat transfer caused by vapour movement. The situation in which moisture and/or air movement occur due to convection or gravity is excluded. The application of ISO 16957:2016 to high moisture content is excluded so that the gravity effect can be neglected. ISO 16957:2016 can be applied to a porous material heavier than about 100 kg/m3, in which radiative heat transfer can be neglected. It specifies the following: a) a non-steady-state method of measuring thermal conductivity; b) an approximation formula for the measurement uncertainty caused by moisture movement and nonuniform moisture distribution (and, thus, a determination of the measuring conditions that satisfy the upper limit of measurement uncertainty); c) an estimate of the heat transfer caused by moisture (vapour) movement.

This International Standard gives methods to calculate design thermal conductivities from declared thermal conductivities for the calculation of the thermal performance of building equipment and industrial installations. These methods are valid for operating temperatures from -200 °C to +800 °C. The conversion factors, established for the different influences, are valid for the temperature ranges indicated in the relevant clauses or annexes.

ISO 8143:2010 specifies the requirements for factory-made calcium silicate products which are used for thermal insulation of industrial installations and building equipment with an operating temperature of up to approximately +1 100 °C. NOTE Calcium silicate products can be used at temperatures lower than 0 °C. For operating temperatures below 0 °C, special tests, regarding the suitability of the product in the intended application, are advised (e.g. liquefaction of oxygen). It is advisable to seek the advice of the manufacturer(s) in all cases. The products are manufactured in the form of boards, pipe sections, segments and prefabricated ware. ISO 8143:2010 describes product characteristics and includes procedures for testing, evaluation of conformity, marking and labelling. Products covered by ISO 8143:2010 are also used in prefabricated thermal insulation systems and composite panels; the structural performance of systems incorporating these products is not covered.
