4.4. For fuel grade RT, after the introduction of additives, it is allowed to change the color of the plate to orange, dark orange or raspberry, as well as individual spots of the same colors.
4.5. Fuel poured into a glass cylinder with a diameter of 40-55 mm, when viewed in transmitted light, must be transparent and not contain mechanical impurities and water suspended and settled on the bottom of the cylinder.
If there are disagreements in assessing the quality of TS-1 and RT fuels in terms of mechanical impurities, the analysis should be carried out in accordance with GOST 10577-78, while the mass fraction of mechanical impurities in the fuel should not exceed 0.0003%.
4.6. To determine the thermal-oxidative stability by the dynamic method according to GOST 17751-79, 100 dm 3 of RT fuel are taken from the commodity tank into barrels or cans made of galvanized iron, aluminum or stainless steel.
(Revised edition, Rev. No. 1).
4.7. The content of the amount of water-soluble alkaline compounds is determined by the following method: 300 cm 3 of the test fuel, preheated to 70-80 ° C, and 100 cm 3 of distilled water, previously checked for the absence of alkali, are poured into a separating funnel, for which 100 cm 3 of distilled water is evaporated to a volume of 10 cm 3 and add 3 drops of phenolphthalein. The reaction must be neutral.
The contents of the separating funnel are shaken for 5 minutes. After a 10-minute settling, the aqueous extract is poured into a heat-resistant glass or flask, evaporated to 10-12 cm 3 and 3 drops of phenolphthalein are added.
The fuel does not contain the amount of water-soluble alkaline compounds in the absence of coloring of the evaporated water extract.
A rejection sign is the presence of an alkaline reaction of the evaporated aqueous extract with respect to phenolphthalein.
4.8. In case of disagreement in assessing the quality of fuels, the calorific value is determined according to GOST 21261-91.
4.9. For T-1 and T-2 fuels, the content of water-soluble acids is determined by the indicator method.
4.10. (Excluded, Change. No. 2).
4.11. In case of disagreement, the arbitration method for testing the quality of fuels is established by the method indicated in Table 1 first.
