1. The requirements of this standard shall apply to liquids, particularly petroleum products, with a kinematic viscosity between 2.8 cSt (1.2E) and 380 cSt (50E), approx. They should not be applied to liquids whose properties and composition may vary during the test. 2. Due to construction deficiencies, the results obtained in the Engler viscometer are less safe and precise than those obtained in capillary type viscometers (according to INDITECNOR 22-3) or in gravitating sphere viscometers (according to INDITECNOR 22-4 ); Therefore, the Engler viscometer should not be used in verification tests, nor will it be tolerated that the results obtained by this instrument be used in calculations, particularly in the calculation of the viscosity index (according to INDITECNOR 22-8), or well, they are converted into dynamic or kinematic viscosity values (in accordance with INDITECNOR 22-7),
