ASTM D665 : Rust Preventing Characteristics of Mineral Oil




  • Fully conforms to ASTM D665, NACE TM-01-72, IP 135
  • Reduces Operator Errors
  • Improved Precision
  • Liquid Bath(-L) or Liquid Free Bath(-TH) 
  • Operation Parameters Adjustable via Color Touch Panel
  • Stirrers Agitating at Precisely 1000 rpm, ±0 rpm
  • Stirrers Adjustable from 0 to 1100 rpm
  • Temperature Range ambient to 70°C
  • Temperature Stability of ±0.1°C

The sequence of bath operation for fully automated models

  • Operator adds 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.
  • 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, 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 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.
  • Steel rods are now ready for visual rating of rusting.

FORZA offers this Automated unit as 2 different types of baths: HEATED TUBES BATH (DRY)  and LIQUID BATH

Advantage of FORZA Heated Tube Baths: Traditional Oil baths are messy, water baths are not suggesting by ASTM because it will cause rust to the sample specimen easily and hence will get wrong results.
