This set of tests is for the High Performance Multiuse Grease specification with a Water Resistance Tag (NLGI HPM + WR specification). It consists of core tests for the HPM requiremsnts and three additional tests to meet the Water Resistance Tag requirements.
HPM Core Requirements:
Core Penetration (60 stroke AND 100,000 stroke) (ASTM D217)
Elastomer Comatability (ASTM D4289)
Oxidation Stability (ASTM D942)
Water Washout (ASTM D1264)
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)
Additional tests of the Water Resistance Tag:
Water Washout Characteristice (Also required in NLGI HPM specification, but with tighter tolerences here. (ASTM D1264) (data from the NLGI HPM specification is used here)
Water Spray off (ASTM D4049)
Roll Stability in the Presence of Water (ASTM D8022)
Price: $3740.00
Sample size: 3 kg
