2.Applicable standards
This instrument is designed and manufactured as per the standards of ASTM D1401 and GB/T7305.
3.Scope
This test method covers measurement of the ability of petroleum oils or synthetic fluids to separate
from water.
The values stated in SI units are to be regarded as the standard. The values given in parentheses
are for information only.
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 of this standard to establish appropriate safety and health
practices and determine the applicability of regulatory limitations prior to use. For specific precautionary
statements.
4.Performance characteristics
Digital display and temperature control. Automatic timing for sample mixing; operating easily
5.Structure characteristics
This equipment mainly consists of temperature control system, control system, and the heating device.Temperature control system utilises thedigital temperature controller to control the temperature, with high precision and stability. Besides, the stirring device is working in the temperature control system.
The control system is composed of the potentiometer and the controlling switch. The heating system is composed of heating tubes.
6.Summary of Test Method
A 40- ml sample and 40-ml of distilled water are stirred for 5 min at 54 in a graduated cylinder.
The time required for the separation of the emulsion thus formed is recorded. If complete
separation or emulsion reduction to 3 ml or less does not occur after standing for 30 min, the
volumes of oil (or fluid ), water, and emulsion remaining at the time are reported.
