24. (1) Every power to make rules conferred by this Act is subject to the condition of the rules being made after previous publication in such manner as the Governor General in Council may, by notification in the Gazette of India, direct.
(2) All rules made by the Governor General in Council or by the Local Government under this Act shall be published in the Gazette of India or the local official Gazette, as the case may be, and on such publication shall have effect as if enacted by this Act.
4. Application of the test.—The water-bath, with its thermometer in position, is placed in some locality where it is not exposed to currents of air, and where the light is sufficiently subdued to admit of the size of the entire test-flame being compared with that of the bead on the cover. The cup is carefully lifted without shaking it, and placed in the bath, the test-lamp is lighted, and the clockwork wound up by turning the key. The thermometer in the oil-cup is now watched, and, when the temperature has reached 56° Fahrenheit, the clockwork is set in motion by pressing the trigger.
If no flash takes place, the clockwork is at once rewound and the trigger pressed at 57° Fahrenheit, and so on, at every degree

degree rise of temperature, until the flash occurs, or until a temperature of 95° Fahrenheit has been reached.
If the flash takes place at any temperature below 77° Fahrenheit, the temperature at which it occurs is to be recorded. Two fresh portions of the sample are then to be successively tested in a similar manner and the results recorded. If no greater difference than 2° Fahrenheit exists between any two of the three recorded results, and if in no instance the flash has taken place within eight degrees of the temperature at which the testing is commenced, each result is to be corrected for atmospheric pressure as hereafter described, and the average of the three corrected results is the flashing point of the sample. In the event of there being a greater difference than 2° Fahrenheit between any two of the results, while in no instance has the flash taken place within eight degrees of the temperature at which the testing was commenced, the series of tests is to be rejected, and a fresh series of three similarly obtained, and so on, until a sufficiently concordant series is furnished, when the results are to be corrected and the average taken in the manner already described.
If, however, a flash has occurred at or below 64° when the test is applied in the manner above described, the next testing shall be commenced ten degrees lower than the temperature at which the flash had been previously obtained (that is to say, at 54° or thereunder), and this procedure shall be continued until the results of three consecutive tests do not show a greater difference than 2° and until a flash has not occurred in any of the three tests within eight degrees of the temperature at which the testing is commenced: Provided always that, if at the commencement of the series of tests a flash has occurred on the first application of the test-flame at 56°, and if a flash has also occurred on the first application of the flame in each of three successive tests in which, thereupon, the test-flame is first applied at 46° as above directed, the testing officer shall certify that the petroleum has a flashing point below 47°, and the sample shall be reported dangerous.
If a temperature of 76° Fahrenheit has been reached without a flash occurring, the application of the test-flame is to be continued at every degree rise of temperature until a temperature of 95° Fahrenheit has been reached. If no flash has occurred up to this point, and if the petroleum is declared to be imported subject to the provisions of the Act, the tests shall not be continued, and the testing officer shall certify that the petroleum has a flashing point over 95° and is not dangerous. But, if the petroleum is oil ordinarily used for lubricating purposes and is declared to have its flashing point at or above 200° or is oil

oil to which a notification of the Local Government exempting it from the operation of the Act will be applicable in the event of the flashing point being found to be at or above 120°, the test shall be continued as follows:—The oil-cup is to be removed from the water-bath, and the temperature of the water in the water-bath is to be reduced to 95° Fahrenheit by pouring cold water into the funnel (the hot water escaping by the overflow-pipe). The air-chamber is then to be filled to a depth of 1½ inches with water at a temperature of about 95° Fahrenheit, the oil-cup is to be replaced in the water-bath and the spirit-lamp attached to the water-bath is to be lighted and placed underneath. The test-flame is then to be again applied, from 96° Fahrenheit, at every degree rise of temperature as indicated by the thermometer in the oil-cup until a flash takes place or until a temperature of 200° Fahrenheit or 120° Fahrenheit, as the case may be, has been reached. If during this operation the test-flame appears to diminish in size, the lamp is to be replenished in the manner prescribed at 2 without interrupting the test.
If a flash occurs at any temperature between 76° and 200° Fahrenheit, the temperature at which it occurs, subject to correction for atmospheric pressure, is the flashing point of the sample.
In repeating a test a fresh sample of oil must always be used, the tested sample being thrown away, and the cup must be wiped dry from any adhering oil and cooled, as already described, before receiving the fresh sample.
