意义和目的
4.1 测试方法 A 是使用现成实验室设备和玻璃器皿的直接方法. Test method A can only be used with powders that do not contain metallic pigments.

4.2 Test Method B provides better precision at a higher cost and includes metals, although different models yield different overall averages for each of the three samples tested.

4.3 Test method C can be used when the recipe is known and the density of each ingredient is available.
