标准摘要
[中文适用范围]： 本标准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。 如果待测试的材料包括在模制/挤出过程中形成的表层，则可以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表皮，则术语“总密度”不适用。 对于成型材料，可以使用不同的方法，例如浮力法。 [外文原描述]： 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.
