3. TEST METHODS

3.1. Sampling - according to GOST 9980.2.

3.2. Preparation of samples for testing

The test whites are thoroughly mixed. The mass fractions of the film-forming substance, the solid, the zinc compounds in terms of ZnO in the solid and the degree of grinding are determined without diluting the white.

To determine the rest of the indicators, the white is diluted to a paint consistency with natural drying oil in an amount of 17-28% by weight of thick white, filtered through a sieve with a mesh 056N GOST 6613 and applied with a brush to the prepared plates.

Plates for applying whitewash are prepared according to GOST 8832, Sec. 3.

The color of the film and the drying time of the whitewash are determined on plates of steel grades 08 kp and 08 ps with a size of 70 x 150 mm and a thickness of 0.5-1.0 mm according to GOST 16523 or on plates of black cold-rolled sheet with a thickness of 0.25-0.28 mm according to GOST 13345.

The hardness of the film is determined on glass for photographic plates measuring 9 x 12-1.2 according to TU 6-43-02-05133-03.

To determine the drying time and the hardness of the film, the white is applied in one layer.

The thickness of a single-layer coating after drying should be 25-30 microns. The film thickness is measured with an MP-25 type micrometer according to GOST 4381 or another device with an error of no more than + 3 microns.

To determine the color of the white is applied until the substrate is completely covered.

Drying is carried out at a temperature of (20 + 2) ° C for 24 hours.

(Changed edition, Rev. No. 1, 2).

3.3. The color of the dried white film is determined by visual comparison with the color of the corresponding control color samples in natural or artificial daylight diffused light. The compared samples should be in the same plane at a distance of 300-500 mm from the observer's eyes at an angle of view that excludes surface glare. In case of disagreement in the assessment of color, the determination of the color in natural daylight is taken as the final result.

(Revised edition, Rev. No. 2).

3.4. Mass fractions of a solid substance and a film-forming substance are determined according to GOST 17537. A mixture of acetone (GOST 2768) with ethyl alcohol (GOST 17299) in a ratio of 3:2 is used as a solvent.
