Notes
1 An increase in the viscosity of natural drying oil during storage up to 37 s and a decrease in the iodine number to 150 is not a rejection sign
2 When using imported linseed oil, an iodine number of at least 150 is allowed
(Changed edition, Rev. No. 1, 2).
2. ACCEPTANCE RULES
2.1. Acceptance rules - according to GOST 9980.1-86.
2 2. The manufacturer conducts tests according to subparagraphs 8, 9 and 11 of the table periodically on every twentieth batch. Upon receipt of unsatisfactory results of repeated periodic tests, the supply of drying oil to the consumer is terminated until the reasons for their non-compliance with the requirements of this standard are clarified and eliminated and satisfactory test results are obtained for new batches.
3. TEST METHODS
3.1. Sampling - according to GOST 9980.2-86.
3 2. Transparency is determined according to GOST 5472-50, for this drying oil is poured into a cylinder with a capacity of 10 cm 3 or a test tube made of colorless glass.
3.3. Sludge is determined according to GOST 5481-66, Sec. 2 after settling drying oil for 24 hours at (20:±2) 0 С.
3.3a. The relative viscosity is determined using a VZ-246 (or VZ-4) type viscometer with a nozzle diameter of 4 mm at a temperature of (20±0.5)°C.
(Introduced additionally, Amendment No. 2).
If a brown precipitate of manganese dioxide precipitates during the processing of ash with a mixture of nitric and sulfuric acids, due to the presence of a manganese desiccant in the drying oil, the solution should be filtered through a paper filter; wash the beaker and the filter with the precipitate with 10 cm 3 of a mixture of acids, draining the washing water into the filtrate.
(Revised edition, Rev. No. 1).
3.6. Qualitative determination of resin acids is carried out on three samples.
(Revised edition, Rev. No. 1).
3.6.1. Used reagents and solutions:
acetic anhydride according to GOST 5815-77;
sulfuric acid according to GOST 4204-77;
petroleum ether;
copper acetate according to GOST 5852-79, aqueous solution with a mass fraction of copper acetate 3%;
liquid synthetic ammonia according to GOST 6221-82
3.6.2. Conducting a test
Reaction with sulfuric acid
0.1 g of drying oil is dissolved in 3 cm 3 of acetic anhydride. A drop of sulfuric acid is added to the solution. In the presence of resin acids, the solution turns dark purple.
Reaction with copper acetate
OD g of drying oil is dissolved in 3 cm 3 of petroleum ether, a solution of copper acetate is added and shaken. In the presence of resin acids, the drying oil solution turns emerald green, and the aqueous solution of copper acetate becomes colorless.
Reaction with ammonia
0.1 g of drying oil is dissolved in 3 cm 3 of petroleum ether, 1-2 drops of ammonia are added and shaken. In the presence of resin acids, gelatinous ammonium abietinate is released.
The absence of resin acids is considered proven if all three or the first two give a negative result.
3.6.1; 3.6.2. (Revised edition, Rev. No. 2).
3.7. Drying time is determined according to GOST 19007-73.
A glass rod with a diameter of 3-4 mm is immersed in drying oil to a depth of about 3 cm and 4 drops of drying oil are applied to a glass plate measuring 9X12 cm. Then the drying oil is evenly distributed over the entire surface of the plate.
(Introduced additionally, Rev. No. 1).
4. PACKAGING, LABELING, TRANSPORT AND STORAGE
4.1. Packaging - according to GOST 9980.3-86.
4.2. Container marking - according to GOST 9980.4-86.

3. TEST METHODS
3.1. Sampling - according to GOST 9980.2-86.
3.2. Transparency is determined according to GOST 5472-50, while drying oil is poured into a cylinder with a capacity of 10 cm 3 or a test tube made of colorless glass.
3.3. The sludge is determined according to GOST 5481-66, section 2 after settling the drying oil for 24 hours at (20±2) °C.
3.3a. The relative viscosity is determined by a viscometer of the VZ-246 type (or VZ-4 with a nozzle diameter of 4 mm at a temperature of (20 ± 0.5) ° C.
(Introduced additionally, Rev. N 2).
3.4. The content of phosphorus-containing substances is determined according to GOST 7824-80, section 2, while taking 5 g of drying oil.
If a brown precipitate of manganese dioxide precipitates during the processing of ash with a mixture of nitric and sulfuric acids, due to the presence of a manganese desiccant in the drying oil, the solution should be filtered through a paper filter; Rinse the beaker and the filter with the precipitate with 10 cm3 of a mixture of acids, draining the washing water into the filtrate.
(Changed edition, Rev. N 1).
3.6. Qualitative determination of resin acids is carried out on three samples.

petroleum ether;
copper acetate according to GOST 5852-79, aqueous solution with a mass fraction of copper acetate 3%;
liquid synthetic ammonia according to GOST 6221-82*.
______________
* On the territory of the Russian Federation, GOST 6221-90 applies. - Database manufacturer's note.
3.6.2. Conducting a test
Reaction with sulfuric acid
0.1 g of drying oil is dissolved in 3 cm3 of acetic anhydride. A drop of sulfuric acid is added to the solution. In the presence of resin acids, the solution turns dark purple.
Reaction with copper acetate
0.1 g of drying oil is dissolved in 3 cm of petroleum ether, a solution of copper acetate is added and shaken. In the presence of resin acids, the drying oil solution turns emerald green, and the aqueous solution of copper acetate becomes colorless.
Reaction with ammonia
0.1 g of drying oil is dissolved in 3 cm of petroleum ether, 1-2 drops of ammonia are added and shaken. In the presence of resin acids, gelatinous ammonium abietinate is released.
The absence of resin acids is considered proven if all three or the first two give a negative result.
3.6.1; 3.6.2. (Changed edition, Rev. N 2).
