ASTM D2511 Standard Test Method for Thermal Shock Sensitivity of Solid Film Lubricants
4. Summary of Test Method
4.1 A steel panel having the solid film lubricant deposited on one surface is subjected to 260°C (500°F) heat followed by immediate exposure to -54°C (-65°F). The solid film is then examined for cracking, flaking, blistering, or other evidence of thermal instability.
5. Significance and Use
5.1 Solid lubricant coatings are applied to surfaces that are exposed to heat and cold to such a degree that in many cases liquid lubricants are not practical. Adherence under these conditions is mandatory to preserve the bearing surfaces during sliding motion.
