Work Item s – proposed revisions of this standard.

The stirrer motor is securely fixed aetm only a vertical range of motion without the use of belts or chains. It is used for specification of new oils and monitoring of in-service oils.

Model is a robust 7 position apparatus that meets the full requirements of ASTM D and related Water Separability demulsibility methods by testing an emulsion formed by stirring water and a lubricating oil sample.

For higher viscosity oils where there is insufficient mixing of oil and water, Test Method D is recommended. When agitation is stopped an audible alarm is sounded to alert the user. The stirrer paddle and shaft is machined from a single piece of stainless steel.


The enclosed cabinet design gives the unit a stable footprint less prone to topple over and safer in high temperature applications than open jar designs. The stirrer speed RPM is measured by a tachometer and digitally displayed.

This paddle reduces the possible micro crevices which may accumulate contamination. Time is saved in alignment for the next test and future mechanical problems are avoided by keeping the motor fixed and use of a sample turntable that locks in place at each position.

ASTM D Water Separability | Lawler Manufacturing

It is the responsibility of the d401 of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. These f1401 are difficult to remove in paddles of conventional soldered shaft and paddle construction.

The Lawler design permits lifting for paddle and sample removal. A color touch panel, which is friendlier than single line displays, is used to display temperature and RPM plus control the unit.

No other units of measurement are included in this standard.


The bath cover reduces water loss and has the capacity for 7 graduated test cylinders. Additional safeguards include low level, over temperature, and circuit breaker protection. For specific warning statements, see Section 7. The bath jar is easily removable from the rear.

The unit is backlit for easier reading of the emulsion separation line. Plus it also has built in timers for each position to avoid the need for stopwatches. The temperature is digitally displayed with a resolution of 0. Historical Version s – view previous versions of standard.
