OECD 109 OECD Guidelines for the Testing of Chemicals Standard Test Method

EUROLAB laboratory provides testing and compliance service within the scope of OECD 109 standard. The OECD Guidelines for testing chemicals are a collection of approximately 150 of the most relevant internationally recognized test methods used by government, industry and independent laboratories to identify and characterize the potential hazards of chemicals.

These are a set of tools for professionals primarily used in regulatory safety testing and beyond.

This test guide lists methods for determining the density of liquids and solids and gives only a brief description of them. The density of a substance is the division of its mass and volume and is expressed in SI units kg/m3 at a given temperature.

A few methods are for liquids only: hydrometer, submerged body method (both are buoyancy methods), and oscillating density meter. These methods are applicable to liquids with dynamic viscosity below 5 Pa.s for the hydrometer and oscillating density meter and below 20 Pa.s for the immersed body method.

The solids-only method is the air comparison pycnometer and pour and tap. Methods for both liquids and solids are hydrostatic equilibrium (a method of lifting) and pycnometry. The dynamic viscosity of the fluids to be investigated should not exceed 5 Pa.
