Recent developments have accelerated the ASTM development of a silver corrosion test by fuels. The new ASTM method will soon be made part of ASTM D4814 and is, in large measure, based on D130 test bomb method.
Model 279-4 is an insulated stainless steel liquid bath able to accept 4 test bombs holding the test fuel and the silver strip. The temperature range of Model 279-4 is 30° to 150°C with temperature stability of ±0.2°C. Temperature is controlled with a digital display controller with 0.1°C resolution. To prevent overheating, a high limit switch is provided to interrupt power to the bath in the event of primary controller failure. A float switch interrupts power to the bath in the event of low bath fluid level.
The bath is mechanically agitated to insure test point to test point uniformity. A cover over the bath is provided to reduce evaporation (if water is used as a bath medium).
Model 279-8 and Model 279-12 are identical to Model 279-4 except are larger and able to accept 8 and 12 test bombs, respectively.
Model 291-6 is an insulated stainless steel liquid bath deep enough to be able to accept 6 test tubes conforming to IP 227 silver corrosion test method. The temperature range of Model 291-6 is 30° to 150°C with temperature stability of ±0.2°C. Temperature is controlled with a digital display controller with 0.1°C resolution. To prevent overheating, a high limit switch is provided to interrupt power to the bath in the event of primary controller failure. A float switch interrupts power to the bath in the event of low bath fluid level.
Model 295-8 is a solid aluminum block bath deep enough to accept 8 test tubes (350 mm long) as per IP 227. The dry block bath removes the disadvantages of liquid baths, such as smoke, fire hazard, cleanliness, safety, etc.
