This Standard specifies requirements for five basic series (L20, L50, M50, M100 and S50) of glass density hydrometers of constant mass that are graduated to indicate density (kg/m3 or g/cm3) at 20 °C or 15°C (hereafter referred to as density hydrometers).

Each series comprises density hydrometers which between them cover the interval 600 kg/m3 to 2 000 kg/m3 (0.600 g/cm3 to 2.000 g/cm3).

The density hydrometers are graduated appropriately for use in liquids of low, medi urn or high surface tension.

The density hydrometers are required to follow the principles of construction and adjustment specified in ISO 387.

This Standard does not cover density hydrometers with a built-in thermometer.

A table of standard categories of surface tension is given in Annex A.

A table of recommended stem diameters is given, for guidance in manufacture, in Annex B.

Examples of form of density hydrometer are shown in Figure 1.

The requirements for density hydrometers used for transactions or certifications are given in Annex JA and Annex JB.

NOTE The International Standard corresponding to this Standard and the symbol of degree of correspondence are as follows.

ISO 649-1: 1981 Laboratory glassware-Density hydrometers for general purposes-Part 1: Specification (MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standard and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/IEC Guide 21-1.
