А Префаце
ИСО (Међународна организација за стандардизацију) је глобална федерација националних тела за стандардизацију (Тела чланица ИСО). Развој међународних стандарда се обично спроводи преко ИСО техничких комитета. Свака група чланова заинтересована за тему за коју је основан технички комитет има право да буде заступљена у комисији. Међународне организације, владе и невладине организације које су у вези са ИСО такође су укључене у овај напор. ИСО блиско сарађује са Међународном електротехничком комисијом (ИЕЦ) о свим питањима електротехничке стандардизације.

Увод
This method is used to measure the density and determine the volume of dry coating obtained from a given volume of liquid coating. This volume is considered a very meaningful measure of the coverage of paints, varnish, or related products (the surface area covered per unit volume specified by the thickness of dry film). The values obtained by this method may differ from those calculated based on the addition of the mass and volume of the raw materials in the formulation. Due to the shrinkage or expansion of the resin and solvent, the combined volume occupied by the resin and solvent can be the same, greater or less than the combined volume of the individual components. The second factor affecting the volume of the dry paint formulation is the extent to which the space between the pigment particles is filled by the adhesive.

Above and close to the critical pigment volume concentration, the volume of dry paint film is larger than the theoretical volume, which is due to the increase of unfilled voids between pigment particles. The porosity of the film means that this approach is not appropriate.

The volume value of the non-volatile matter depends on the temperature and time of heating, and these conditions should be carefully considered for the material under test.

1 Обим примене
This document specifies a method for determining the non-volatile material volume (NV V) of coatings and related products by measuring the density of dried coatings over any specified temperature range and drying or curing periods. This method is used to determine the non-volatiles immediately after use.

Using the volume results of the non-volatile matter obtained according to this document, the spread rate of the coating material can be calculated.

The method specified in this document is the selection method for air drying materials. Its use of other materials has not been tested.

Annex B provides an overview of available methods for determining the content and volume of nonvolatile substances.

This document does not apply to coatings exceeding the critical pigment volume concentration.

3.1 Non-volatile substances

Mass residue obtained by evaporation under specified conditions

Ентри Ноте 1: Instead of the term “non-volatile matter”, different terms such as solid, dry residue, dry matter, solid matter, drying residue are usually used with their respective abbreviations. Термин “non-volatile substance”, also used in ISO 3251, should be used together with the abbreviation “NV” instead of these terms.

Белешка 2: This document and ISO 3251 specify different conditions for the determination of NV. Стога, in this document, the symbol NV m is used for non-volatile substances by mass.
