High-Performance Multiuse (HPM) Grease Specification
The National Lubricating Grease Institute’s (NLGI) New High-Performance Multiuse (HPM) Grease Specification provides unified industry guidance on the performance of grease and is “chemistry neutral.” The specification is designed with tests and limits for enhanced performance in the areas of water resistance, high load carrying capacity, saltwater corrosion resistance, and low-temperature performance. The performance-based specification ensures the grease can support these areas and can extend or maintain the operation of equipment. The specification’s limits are “challenging yet achievable” in order to set a new performance standard that grease users and specifiers can utilize for selecting greases to use in their applications.
Savant Labs are positioned to address your pre-certification grease testing needs. The core HPM specification testing includes:
| International ASTM Method | |
|---|---|
| D217 | Cone Penetration, Worked & 60 Strokes |
| D217 | Cone Penetration, Extended Worked (100,000 Strokes) |
| D4289 | Grease Compatibility with NBR L Elastomer |
| D942 | Oxidation Stability |
| D1264 | Water Washout Characteristics of Greases |
| D1478 | Low Temperature Torque |
| D1742 | Oil Separation, Storage of Grease |
| D6184 | Oil Separation Percent, Wire Cone Conical Sieve Method |
| D1831 | Roll Stability of Grease |
| D2266 | Four Ball Wear |
| D2596 | Extreme-Pressure Properties of Lubricating Grease |
| D1743 | Rust & Corrosion Prevention Properties of Grease |
| D6138 | Corrosion-Preventive Properties Under Dynamic Wet Conditions (Emcor Test) Distilled Water |
| D4048 | Detection of Copper Corrosion |
The testing for the sub-categories are listed below:
High-Performance Multiuse grease specification + Corrosion Resistance
