Chemical condition, freeze/boil protection, corrosion-related elements and contamination indicators.| Test / parameter | Published method | Technical purpose | Interpretation context | Capability |
|---|---|---|---|---|
| Colour | CTP T112 | Records the visible condition and colour of the submitted sample. | Unexpected haze, sediment, separation or colour change may indicate contamination, degradation or sample-handling effects; compare with the product reference. | Inhouse |
| pH | ASTM D1287 | 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 |
| Total Dissolved Solids | CTP T093 | 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 |
| Chloride Content | ASTM D3634 | Quantifies the selected dissolved ion or nutrient-related parameter. | A higher or lower result is assessed against the identified water-use requirement and may indicate source, treatment, contamination or process effects. | Inhouse |
| Sulphate Content | ASTM D5827 | Quantifies the selected dissolved ion or nutrient-related parameter. | A higher or lower result is assessed against the identified water-use requirement and may indicate source, treatment, contamination or process effects. | Inhouse |
| Nitrate Content | ASTM D5827 | Quantifies the selected dissolved ion or nutrient-related parameter. | A higher or lower result is assessed against the identified water-use requirement and may indicate source, treatment, contamination or process effects. | Inhouse |
| Total Hardness | CTP T164 | 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 | CTP T144 | 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 |
| Elemental Analysis - Wear and Corrosion Metals | ASTM D6130 | 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 |
| Reserve Alkalinity | ASTM D1121 | 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 |
| Foaming Tendency | ASTM D1881 | Assesses foam tendency and, where applicable, foam stability. | Higher foam volume or persistence may indicate poorer air-release behaviour, contamination or additive-related change under the test conditions. | Inhouse |
| Equilibrium Reflux Boiling Point | ASTM D1120 | Characterises volatility and recovery across the boiling range. | Higher or lower recovery temperatures may indicate composition change, contamination or a different product grade when compared with the applicable specification. | Inhouse |
| Freezing Point | ASTM D3321 | Measures or evaluates freezing 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 |
| Water Content | ASTM E203 | 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 |
| Glycol Content | Refractometer | Measures or evaluates glycol 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 |
| Oxalate, Formate and Inorganic Ions | ASTM D5827 | Measures or evaluates oxalate, formate and inorganic ions 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 |
