ISO 845:2006规定了测定泡沫塑料和橡胶的表观总密度和表观芯密度的方法。
如果待测材料包括模塑/挤压过程中形成的外皮,则可确定表观总密度或表观芯密度,或两者。如果材料在模制过程中没有形成外皮,则术语“总密度”不适用。
ISO 845:2006 specifies a method for determining the apparent overall density and the apparent core density of cellular plastics and rubbers.
If the material to be tested includes skins formed during a moulding/extrusion, the apparent overall density or the apparent core density, or both, can be determined. If the material does not have skins formed during moulding, the term "overall density" is not applicable.
