This set of tests includes all testing required for the NLGI HPM Core testing. The testis include
Core Penetration (60 stroke AND 100,000 stroke) (ASTM D217)
Elastomer Compatability (ASTM D4289)
Oxidation Stability (ASTM D942)
Water Washout (ASTM D1264) @ 79C
Low Temperature Torque (-20C)(ASTM D1478)
Oil Separation (ASTM D1742 AND D6184)
Roll Stability (ASTM D1831)
Four Ball Wear (ASTM D2266 AND ASTM D2596)
Corrosion Prevention (ASTM D6138 (distilled water) AND ASTM D1743)
Copper Corrosion (ASTM D4048)
Links to the required tests are in the related tests listed below.
Ater the core tests are passed, performance tags may be added for more specific applications. There are 4 perforamnce tags that may be added:
Water Resistance (HPM+WR)
Salt-Water Corrosion (HPM + CR)
High Load (HPM + HL)
Low Temperature (HPM + LT)
Please note that all tests in the core specification must be passed before a performance tag can be added. Multiple performance tags may be added to the same grease. The core test with the Performance tags are included as separate entries.
