适用范围： This standard prescribes the general procedures and design of equip-ment for determining the thermal conductivity of dry samples of thermal insulating materials, provided that:a) the materials are sufficiently uniform with regard to their aggregates and pores; andb) the thermal conductivity of the material does not exceed l·5W/mK. The equipment described in this standard is suitable for hot face temperature between 675 K and 1 275 K. The thermal conductivity coefficients obtained apply only to the particular sample tested.
