1 Scope This standard is one of a series of standards dealing with the sampling and testing of paints, varnishes and related products. This standard specifies a procedure for determining the volume percentage of non-volatile matter in paints, varnishes and related products by measuring the density of a dried coating for any specified temperature range and period of drying or curing. The method is not suitable for paints formulated above the critical pigment volume concentration. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this standard. For dated reference, subsequent amendments to (excluding any corrigendum), or revisions of, any of these publications do not apply. However, parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. For undated references, the latest edition applies. GB/T 1725-2007 Paints, varnishes and plastics - Determination of non-volatile-matter content (ISO 3251: 2003, IDT) GB/T 3186-2006 Paints, varnishes and raw materials for paints and varnishes - Sampling (ISO 15528: 2000, IDT) GB/T 6750-2007 Paints and varnishes - Determination of density - Pyknometer method (ISO 2811-1: 1997, IDT) GB/T 20777-2006 Paints and varnishes - Examination and preparation of samples for testing (ISO 1513: 1992, IDT) ISO 2811-2: 1997 Paints and varnishes - Determination of density - Part 2: Immersed body (plummet) method ISO 2811-3: 1997 Paints and varnishes - Determination of density - Part 3: Paints and varnishes - Determination of density - Part 3: Oscillation method ISO 2811-4: 1997 Paints and varnishes - Determination of density - Part 4: Pressure cup method 3 Terms and definitions For the purposes of this standard, the following terms and definitions apply. 3.1 volume of non-volatile matter the volume of the residue obtained when a uniform and specified thickness of the product under test is cured or dried at a specified temperature for a specified period 4 Principle A receptacle (disc or plate) is weighed in air and in water (or other suitable liquid of known density), coated with the product to be tested, dried and reweighed in air and in the same liquid. From these measurements, the mass, the volume and hence the density of a dried coating are calculated. From the determinations of liquid coating density (GB/T 6750-2007), non-volatile matter by mass and dry coating density, the non-volatile matter by volume is calculated.
