Metalworking fluids
Condition, concentration, contamination and performance-related tests for neat and water-miscible fluids.| Test / parameter | Published method | Technical purpose | Interpretation context | Capability |
|---|---|---|---|---|
| Kinematic Viscosity at 40 °C and 100 °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 |
| Viscosity Index | ASTM D2270 | 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 |
| Total Acid Number | ASTM D664 | Measures acidic constituents under the selected method. | An increase from the reference may support oxidation or acidic-contamination review; a single result must be compared with product and service history. | Inhouse |
| Flash Point | ASTM D92 | Determines the temperature at which vapour ignites under the selected procedure. | A lower result may indicate volatile contamination or product change; a higher result is interpreted against the identified grade and method. | Inhouse |
| Moisture Content | ASTM D95 | 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 |
| i-pH Value | ASTM D7946 | Measures acidity or alkalinity of the sample under the selected procedure. | A result above or below the required range may affect treatment control, corrosion, scaling, process suitability or product conformity. | Inhouse |
| Sulphur Content | ASTM D4294 | Quantifies sulphur in the submitted fuel or material. | A higher result may affect specification compliance, emissions-related requirements or process suitability; compare with the identified grade. | Inhouse |
| Elemental Analysis | ASTM D5185 | 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 |
| Copper Strip Corrosion | ASTM D130 | Measures or evaluates copper strip 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 |
| Rust Test | ASTM D665 | Measures or evaluates 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. | Outsourced |
| Chlorine Content | ASTM D4929 | Measures or evaluates chlorine content 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 |
| Sediments | ASTM D4055 | Assesses particulate, sediment or insoluble contamination in the sample. | A higher result indicates more suspended or insoluble material; acceptability depends on the equipment, product specification and sampling point. | Inhouse |
| Ferrography | ASTM D7680 | Measures or evaluates ferrography 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 |
| Particle Count | ISO 4406 / NAS 1638 | Assesses particulate, sediment or insoluble contamination in the sample. | A higher result indicates more suspended or insoluble material; acceptability depends on the equipment, product specification and sampling point. | Inhouse |
| pH | pH Meter | Measures acidity or alkalinity of the sample under the selected procedure. | A result above or below the required range may affect treatment control, corrosion, scaling, process suitability or product conformity. | Inhouse |
| Tramp Oil | Acid Split | Measures or evaluates tramp oil 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 |
| Concentration | Acid Split / Refractometer | Measures or evaluates concentration 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 |
| Bacteria Count | Kit Method | Assesses the selected microbiological indicator or organism group. | Detection or a higher count indicates greater microbiological loading; interpretation must follow the applicable water-use requirement and sampling controls. | Inhouse |
| Hardness | Titration | Measures hardness-forming minerals or their contributing ions. | Higher values can increase scaling tendency; very low values may be relevant to corrosivity or treatment control depending on the application. | Inhouse |
| Conductivity | Conductivity Meter | Assesses ionic or dissolved-material content in water. | A higher result generally indicates more dissolved ionic material; significance depends on the water source, treatment and intended use. | Inhouse |
