ISO 2245:2006根据加热时尺寸永久变化的测定,规定了成型隔热耐火材料产品的分类,并根据体积密度进行二级分类,以涵盖轻质产品(L类)。不包括由陶瓷纤维构成的产品。
ISO 2245:2006 specifies a classification of shaped insulating refractory products, based on the determination of permanent change in dimension on heating, with a secondary classification based on bulk density to cover lightweight products (Class L). Products composed of ceramic fibres are excluded.
