Short answer
For mixtures, each component appearing suitable individually does not prove that the mixture is also suitable. The actual composition, ratio, temperature and mode of contact must be communicated to the manufacturer. Instead of vague trade names, the product document and a written assessment with a clear scope should be used.
Technical explanation
Chemical resistance tables mostly provide information for specific substances and defined conditions. Mixture effects or special applications may fall outside the table's scope. In addition, commercial products may contain additives, solvents and different components. The seals and other wetted materials are assessed as well as the inner tube. Automatically applying a favorable row for one component to the mixture amounts to presenting a result that is not in the table as if it had been produced.
Topic-specific checkpoints
| Item | Description |
|---|---|
| Mixture identity | Manufacturer/product name and current document revision. |
| Actual use | Ratio, temperature, duration and cycle frequency. |
| Assembly list | All materials in contact with the fluid. |
| Response scope | Approved conditions, limitations and points left open. |
How is it assessed in practice?
Attach the safety data sheet, the technical product document and the actual mixing ratio used to the assessment file to be sent to the manufacturer. If the full composition is not shared due to trade secrecy, state this explicitly and determine a secure information-sharing route with the parties involved. For example, switching to a different brand of cleaner is not just a purchasing change; the composition may change even under the same usage name. Record the response received together with the product code, temperature and duration; do not summarize it with a general label such as 'chemical resistant'.
Original editorial recommendation; not a clause of a standard.
Frequently asked questions
Does the safety data sheet approve hose suitability?
No. The sheet is an important input for the assessment; it does not replace the material and service suitability approval for a specific hose assembly.
