1 Scope
1.1 This standard is applicable to the determination of water separability of petroleum oils and synthetic fluids.
This standard is applicable to determination of oils having viscosities of 28.8mm2/s~90mm2/s at 40℃ and the test temperature is 54℃±1℃. However, the test temperature shall be raised to 82℃±1℃ when testing oils more viscous than 90mm2/s at 40℃. For higher viscosity oils where there is insufficient mixing of oil and water, the test method specified in GB/T 8022 is recommended. Other test temperatures such as 25℃ may also be used.
When testing synthetic fluids whose relative densities are greater than that of water, the procedure is unchanged, but it shall be noted that the water will probably float on the emulsion or synthetic fluid.
1.2 This standard may involve hazardous materials, operations and equipments but this standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
