标准摘要
[中文适用范围]: GB/T 20432的本部分规定了照相加工过程中所用溶液相对密度(比重)测定的通用试验方法。 [外文原描述]: Specifies a method of determining the specific gravity (relative density) of solutions used in photographic processing. Measurement is made by a hydrometer capable of measuring density to 0,001 units, after the test portion has reached thermal equilibrium with a water-bath (at 25 °C).
