ISO Publishes Paint and Varnish Standard - Density

March 10, 2016

The International Organization for Standardization (ISO) has published ISO 2811-1:2016 Paints and varnishes -- Determination of density -- Part 1: Pycnometer method which revises the 2011 version of the standard.

The standard details a method for determining the density of paints, varnishes and related products using a metal or Gay-Lussac pycnometer. The procedure is limited to materials of low or medium viscosity at the temperature of test. The Hubbard pycnometer (see ISO 3507) can be used for highly viscous materials.
