A.5 Preparation A.5.1 Instrument preparation Assemble the instrument according to the instructions of the instrument, connect the air compressor compressed air outlet line to the instrument air inlet and adjust the air flow rate to (30 ± 5) L/min at room temperature. A.5.2 Preparation of the evaporation cup A.5.2.1 The new evaporating cup should be immersed in the new chromic acid washing solution for 6 h before use to remove organic matter, then rinsed with tap water to remove residual acid, and then washed with isooctane, followed by tap water and distilled water. The evaporation cup was thoroughly washed and placed in a constant temperature oven at 180 ° C for 1 h. Place the dried evaporating cup in a desiccator and place it in a weighing chamber for at least 1 h to room temperature. A.5.2.2 The used evaporation cup can be washed with a volume mixture of toluene and dimethylformamide to remove the colloid. If it is not completely removed, it is washed with water and then immersed in the chromic acid washing solution for 30-60 min. The evaporating cup is taken out with stainless steel tweezers, and in the subsequent operation, only the tweezers are used to hold the evaporating cup. Rinse the evaporation cup thoroughly with tap water and distilled water in sequence, and the subsequent operations are the same as those in A.5.2.1. A.6 Test procedure A.6.1 Turn on the power of the instrument, set the heating of the evaporating aluminum bath to 183 °C ± 2 °C, start the air compressor to introduce air into the experimental device, adjust the air pressure to 0.15 MPa, and the flow rate is 30 L ± 5 L per minute (aluminum bath The temperature inside the test cup in the heating hole is 173 ° C ± 2 ° C). A.6.2 Weigh the evaporation cup treated in step A.5.2.1 or A.5.2.2 to the nearest 0.1 mg. The weighed cup is placed in a constant temperature oven and heated. It is taken out in a desiccator with stainless steel tweezers and cooled to room temperature. Weighed, and the difference between the two weighings is not more than 0.5 mg, which is regarded as constant weight. A.6.3 If the oil sample contains suspended or precipitated solid matter, shake the oil sample in the container thoroughly, mix it evenly, immediately filter through the sintered glass funnel, and collect the filtrate into a clean, dry glass sample bottle, press A. 6.4 ~ A.6.10 operation steps. A.6.4 Using a graduated cylinder, inject 50 ml of the oil sample to be tested into each of the constant weight test evaporation cups, then quickly place it in the aluminum bath heating hole (the time for placing the beaker is as short as possible), and immediately cover it. Upper shroud. Each batch of test retained one evaporation cup without oil sample as a blank. A.6.5 Heating After evaporating the oil sample, transfer the evaporation cup from the aluminum bath to the desiccator with stainless steel tweezers and cool it in the balance chamber for about 1 h to room temperature. Observe the color, shape and estimate of the evaporation cup residue. The amount of residue is then weighed to the nearest 0.1 mg. The weighed evaporation cup was placed in an aluminum bath, and after heating for 10 min, it was taken out into a desiccator, cooled to room temperature, and weighed until the difference between the two weighings was not more than 0.6 mg. A.6.6 Isooctane extraction. 25 ml of isooctane was added to each evaporation cup containing gasoline residue and gently rotated for 30 s, allowed to stand for 10 min, and the soluble matter in the residue was dissolved, and the blank evaporation cup was treated in the same manner. A.6.7 Carefully pour out the isooctane solvent to prevent any loss of solid residue. A.6.8 Extract with a second 25 ml isooctane as described in A.6.6 and A.6.7. If the extract is colored, the third extraction should be repeated until the extract is colorless. Observe the amount and shape of the remaining residue in the evaporation cup. A.6.9 Place the extracted evaporation cup in an evaporation bath controlled at 165-175 °C, without placing the flow hood, and let the beaker dry for 10 min. A.6.10 Constant weight. After the drying period, transfer the evaporation cup from the bath to the dryer, place it in the balance chamber and cool to room temperature, weigh the evaporation cup to the nearest 0.1 mg, to the difference between the two weighings. Not more than 0.6 mg. A.7 Calculation of test results A.7.1 The unwashed residue content of motor gasoline is not (mg/100 ml) calculated according to formula (1). A not = 2 000 (M1−M2 M3−M4) (1) A.7.2 The residue content of washing after washing with gasoline in gasoline (mg/100 ml) is calculated according to formula (2). A wash = 2 000 (M5−M2 M3−M6) (2) Where. M1--A.6.5 recorded evaporating cup plus gasoline residue mass, g; Evaporation cup mass recorded by M2--A.6.2, g; The mass of the blank evaporation cup recorded by M3--A.6.2, g; M4--A.6.5 recorded blank evaporation cup mass, g; The sum of the mass of the evaporation cup and the gasoline residue recorded by M5--A.6.10, g; The blank evaporating cup mass recorded by M6--A.6.10, g. A.8 precision The reliability of the test results (95% confidence level) was judged according to the following rules. Repeatability. When the weight of the sample residue is ≤5 mg, the difference between the two test results and the arithmetic mean should not exceed ±0.5 mg. When the value is greater than 5 mg, the difference between the two test results and the arithmetic mean is ±10. Less than %. Reproducibility. In the two laboratories, when the sample residue weight is ≤ 5 mg, the difference between the two test results and the arithmetic mean is not more than ± 0.6 mg. When the amount is greater than 5 mg, the difference between the two test results and the arithmetic mean is within ±12%. A.9 Report A.9.1 The unwashed residue content (A not) and the post-wash residue content (A wash) should be recorded in the report to the nearest 1 mg/100 ml. A.9.2 If the sample has sedimentation and has been filtered before the test, it will be described in the post-wash residue report. A.9.3 Take the arithmetic mean of the two tests as the measurement result of this test. ......
