ASTM D2511 Standard Test Method for Thermal Shock Sensitivity of Solid Film Lubricants
9. Procedure
9.1 Preheat the oven to 260 +/- 5.5°C (500 +/- 10°F) and place the panels in the oven for a period of 3 h.
9.2 After 3 h at 260 +/- 5.5°C (500 +/- 10°F), place the panels directly into the sub-zero cabinet at a temperature of -54 +/- 0.5°C (-65 +/- 5°F). Allow the panels to remain at -54°C (-65°F) for 3 h.
9.3 Remove the test panels and allow them to reach room temperature.
9.4 Examine the coating visually. It may be necessary to test some coatings under nonstandard conditions for special applications (that is, plunging into liquid oxygen after removal from the oven). All such deviations should be noted in the report.
NOTE 1 - If no damage is evident, the coating shall be further tested by the adhesion test given in Procedure B for Silicate or Phosphoric Acid-Bonded Coatings in Test Method D2510.
