Model 391-6 is an agitated liquid bath with 6 test positions conforming to ASTM D665 and related tests. The bath is in all respects the same as Model 390-6 manual apparatus, but with the addition of timing features that make it an automated apparatus. Operator timing errors are thus reduced and the data precision is improved.
Sequence of bath operation:
The operator adds 30 mL of water into each of the 6 reservoirs above each of the beakers.
The operator prepares and inserts the beakers (with test oil, covers, and stirrers) into the bath as per ASTM D665 method. The test rod assembly (includes the steel rod and holder) are mounted on a holding rack above the individual beakers.
The stirrers and the timer are started.
From this point and until the completion of the test the operator is no longer involved.
When the test oil temperature reaches 60°C (as detected by one PT100 temperature probe inserted into one of the test beakers), the steel rod holding rack is automatically lowered such that the steel specimens are inserted into test oil as per ASTM D665.
After 30 minutes of agitation, the 30 mL of water is automatically released into the beakers.
After 4 hours of agitation the holding rack with the steel test rods are automatically raised from the beakers, the stirrers are stopped and an alarm alerts the operator. The timers are reset for the next test.
The steel rods are now ready for visual rating of rusting.
Model 391-4 is identical to Model 391-6 but configured for only 4 test positions.
Model 397-6 is a 6 position heated tube bath (liquid free) also available with same automation features as Model 391-6. This dry heated bath removes the disadvantages of liquid baths, such as smoke, fire hazard, cleanliness, safety, etc.
