Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | Product-specific SDS and technical data sheets apply. Corrosion-inhibitor performance may be evaluated using ASTM D1384 or equivalent laboratory methods. Dosage and acceptance must follow the chemical supplier and engine manufacturer's instructions; no universal marine certification applies. |
|---|---|
| Class Approval | Cooling-water treatment chemicals are generally not class-approved equipment. Use may be subject to the engine manufacturer's requirements, vessel procedures and applicable DNV, ABS, Lloyd's Register, BV or ClassNK environmental and machinery rules. |
Installation, Maintenance & Safety Information
| Installation Notes | Drain, flush and inspect the cooling circuit when required by the engine maker. Add the chemical to the designated expansion or dosing tank using the supplier's calculated dosage. Do not mix different treatments unless compatibility is confirmed. |
|---|---|
| Maintenance Tips | Test inhibitor concentration, pH, chloride level and appearance at the supplier's recommended intervals. Keep the system properly filled, investigate leaks and maintain records of water tests and chemical additions. |
| Safety Notes | Review the current SDS before handling. Wear chemical-resistant gloves, eye protection and suitable protective clothing. Avoid skin and eye contact, provide ventilation and prevent uncontrolled discharge to sea or drains. |
