Specification for density hydrometers shop-only 4 – Example of test1 Scope This British Standard specifies requirements for five basic series of glass hydrometers of constant mass which are graduated to indicate density (kg m3 or g ml) when used at 20 C. Each series comprises hydrometers which between them cover the interval 600 kg m3 to 2 000 kg m3 (0. 6 g ml to 2. 0 g ml). The hydrometers are graduated appropriately for use in liquids of low, medium or high surface tension. The standard also specifies three sub
