Grease
Composition, consistency, stability, corrosion and load-carrying characteristics for lubricating greases.| Test / parameter | Published method | Technical purpose | Interpretation context | Capability |
|---|---|---|---|---|
| Soap or Thickener Type | ICP-OES | Measures or evaluates soap or thickener type under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Inhouse |
| Base Oil Viscosity at 40 °C | ASTM D445 | Characterises resistance to flow and, where applicable, viscosity response to temperature. | Higher viscosity may accompany oxidation, soot or heavier-product contamination; lower viscosity may accompany dilution, shear or lighter-product mixing. | Inhouse |
| Drop Point | ASTM D566 | Measures or evaluates drop point under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Inhouse |
| Worked Cone Penetration - 60 Strokes | ASTM D217 | Measures or evaluates worked cone penetration - 60 strokes under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Inhouse |
| Worked Cone Penetration - Extended Working | ASTM D217 | Measures or evaluates worked cone penetration - extended working under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Inhouse |
| Copper Corrosion | ASTM D4048 | Measures or evaluates copper corrosion under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Inhouse |
| Water Content | ASTM D95 / ASTM D1744 | Quantifies water or moisture in the submitted material. | A higher result may indicate ingress, condensation, storage or handling contamination; significance depends on the product and applicable limit. | Inhouse |
| Elemental Analysis by ICP | ASTM D7303 | Reports selected wear, contaminant, additive or composition-related elements. | Higher or lower values require comparison with formulation, metallurgy, process inputs and trend history; one result alone does not establish the source. | Inhouse |
| Water Washout Characteristics | ASTM D1264 | Measures non-combustible residue remaining after controlled combustion. | A higher result indicates more inorganic residue and may affect fuel quality, deposits or specification compliance. | Inhouse |
| Oil Separation | IP 121 / ASTM D1742 | Measures or evaluates oil separation under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Inhouse |
| Storage Stability | ASTM D1742 | Measures or evaluates storage stability under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Inhouse |
| Heat Stability | ASTM D6184 | Measures or evaluates heat stability under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Inhouse |
| Roll Stability | ASTM D1831 | Measures or evaluates roll stability under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Outsourced |
| Wheel Bearing Leakage Tendency | ASTM D1263 | Measures or evaluates wheel bearing leakage tendency under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Outsourced |
| Four Ball Weld Load | ASTM D2596 | Measures or evaluates four ball weld load under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Inhouse |
| Four Ball Wear Scar Diameter | ASTM D2266 | Measures or evaluates four ball wear scar diameter under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Inhouse |
| Emcor Rust Test | ASTM D6138 | Measures or evaluates emcor rust test under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Inhouse |
| Oxidation Stability | ASTM D942 | Assesses oxidation stability or condition-related spectral indicators. | Greater oxidation-related change may indicate degradation; stability results and spectral trends must be interpreted using the applicable method and reference. | Inhouse |
| Corrosion Preventive Characteristics | ASTM D1743 | Measures or evaluates corrosion preventive characteristics under the published method. | A higher or lower result is interpreted against the applicable specification, sample type and available reference data; direction alone does not establish conformity. | Inhouse |
