FIELD: environmental protection.
SUBSTANCE: imprint of an oiled rag is obtained by exposing it to a given pressure for a set time - with the possibility of transferring this pressure to the paper through a layer of rags evenly placed on the paper and limited in height by a solid object of regular geometric shape. After receiving the print on paper, its appearance is recorded with the ability to enter the received information into a computer and compare it using a computer with the appearance of reference prints previously entered into the computer in the same way as the print of the rag being evaluated. In this case, reference prints are obtained at a mass content of petroleum products in oiled rags of 10, 15, and 25%.
EFFECT: ability to determine the hazard class of oily rags.
