Inspect the gears and bearing for damage, wash them with B-70 gasoline, and then with petroleum ether and dry. Grind the edges of the copper plate, then wash it, dry it and weigh it with an error of not more than 0.0002 g. Install the bearings, gears and the catalyst plate in the box. Close the box and pour 120 cm 3 of the test oil through the inlet tube.

Mark the time and turn on the motor. Set the output power of the generator 128 W and the air flow rate of 1 dm 3 /h. Heat the oil to 155 °C and maintain the temperature with an accuracy of ± 1 °C. After 30 minutes of operation of the machine, an oil sample (2 cm 3) is taken and the kinematic viscosity is determined at 50 ° C (GOST 33). Then oil samples for viscosity determination are taken every 10 hours of machine operation. At the end of the 50-hour test, the machine is stopped, the oil is poured into a clean flask or glass, and the viscosity at 50 ° C and the amount of substances insoluble in petroleum ether and gasoline (separately) are determined according to GOST 6370. Remove the gears and the copper plate, inspect them and describe the condition of the parts and components of the box, bearing gears and the copper plate. Remove deposits from the catalyst plate and weigh it to determine the activity of the oil in relation to copper.

T 2 - weight of weighing bottle with filter and insoluble substances, g.

The test result is taken as the arithmetic mean of two parallel determinations, the allowable discrepancies between which should not exceed 10% relative to the average result of the determination. The amount of insoluble substances less than 0.5% is estimated as their absence.

5.4.1 - 5.4.1.4. (Revised edition, Rev. No. 5).

5.4.2. Method for determining thermal-oxidative stability on a DK-NAMI instrument

Oxidation is carried out at a temperature of (140 ± 2) °C.

(Changed edition. Rev. No.9 )

To determine the mass fraction of the precipitate, the oxidized oil at 50 - 60 ° C is poured from one reaction flask into a clean conical flask with a capacity of 500 cm 3, with a ground stopper. Rinse the reaction flask with the holder with petroleum ether, pouring the solvent into the oxidized oil. All oxidized oil is dissolved in 10 times the volume of petroleum ether and left in a dark place for 24 hours. colorless. The filter with the precipitate is transferred to a weighing bottle and brought to constant weight in an oven at (105 ± 2) °C.

The increase in oil viscosity after oxidation is determined according to GOST 33.

(Revised edition, Rev. No. 7).

5.4.2.2. Results processing

Mass fraction of sediment in oxidized oil ( X os) as a percentage is calculated by the formula

Where T 2 - weight of bottle with filter and sediment;

T 1 - weight of the bottle with a clean filter;

36.5 - weight of oil sample, g.

The test result is taken as the arithmetic mean of two parallel determinations, the allowable discrepancies between which should not exceed 10% relative to the average result of the determination.

The mass fraction of sediment in oxidized oil up to 0.02% inclusive is estimated as its absence.
