Specification for density hydrometers shop-only so that information and experience1 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
