ISO 29771:2008规定了测定隔热材料有机物含量的设备和程序。 该方法旨在测定无机产品的有机含量，即含有低百分比有机化合物的产品，无论是未上色产品还是贴面产品的绝缘材料。 ISO 29771:2008不适用于在存在水合水和/或碳酸盐、硫酸盐等混合物的情况下测定有机物含量。 ISO 29771:2008不适用于测定粘合剂、饰面和/或涂层的有机含量。

ISO 29771:2008 specifies the equipment and procedures for determining the organic content of thermal insulating materials. The method is aimed at determining the organic content for products that are inorganic, i.e. products containing a low percentage of organic compounds, either unfaced products or the insulating material of a faced product. ISO 29771:2008 is not applicable for the determination of organic content in the presence of water of hydration and/or combined carbonate, sulfate, etc. ISO 29771:2008 is not applicable for the determination of organic content of adhesives, facings and/or coatings.
