ASTM D7525， ASTM D7545 Rapid Small Scale Oxidation Stability Tester
A 5ml sample is introduced into a vessel which is then charged with oxygen to 500kPa at a temperature of 15 to 25℃. The test is initiated by starting the heater and heating the pressure vessel to a temperature of 140℃. The pressure is recorded continuously until the breakpoint is reached. Alternatively, the test maybe terminated when a predetermined minimum requirement is reached.

ASTM D972 Evaporation Loss For Lubricating Grease
The loss of volatile materials from greases and oils can adversely effect the original performance characteristics of a lubricant and therefore could be a significant factor in evaluating a lubricant for a specific use. Such volatiles can also be considered contaminants in the environment in which the lubricant is to be used. Correlation between results from this test method and service performance has not been established.

Relative Scuffing Load Carrying Capacity Tester, FZG
KN-FZG Relative Scuffing Load Carrying Capacity Tester conforms to ISO 14635-1 Gears – FZG test procedures—Part 1: FZG test method A/8, 3/90 for relative scuffing load-carrying capacity of oils and ISO 14635-2 – FZG test method A10/16,6R/90 for relative scuffing load-carrying capacity of lubricants with high EP performance. The types of gear failures which may be influenced by the lubricant in use are scuffing, low-speed wear and the gear-surface fatigue phenomena known as micropitting and pitting. In the gear design process, these gear damages are taken into consideration by the use of specific lubricant and service-related characteristic values. For an accurate, field-related selection of these values, adequate lubricant test procedures are required. The FZG test procedures described in this and other parts of ISO 14635 can be regarded as tools for the determination of the lubricant-related characteristic values to be introduced into the load-carrying capacity calculation of gears.

Reid Vapor Pressure Bath
KN-323 Reid Vapor Pressure Bath conforms to ASTM D323 Standard Test Method for Vapor Pressure of Petroleum Products (Reid Method). It used for testing the vapor pressure (Because the external atmospheric pressure is counteracted by the atmospheric pressure initially present in the vapor chamber, the Reid vapor pressure is an absolute pressure at 37.8°C (100°F) in kilopascals (pounds-force per square inch)
