标准摘要
[中文适用范围]： ISO 2811 的这一部分规定了使用压力杯测定油漆、清漆和相关产品密度的方法。 该方法适用于充气的产品。 例如，乳胶漆通常会捕获小气泡，并且在测量密度时这些气泡可能仍然存在。 然而，它不适用于含有粗颗粒的纹理涂料。 [外文原描述]： ISO 2811-4:2011 specifies a method for determining the density of paints, varnishes and related products using a pressure cup. The method is suitable for products which are aerated. Emulsion paints, for example, often trap small air bubbles, and these might still be present when the density is measured. It is not, however, suitable for textured paints which contain coarse particles.
