Bulk Coating Filling Trials: Water Testing Does Not Validate Product Compatibility

A water trial may answer limited mechanical questions, but it does not establish that a filling system is suitable for the actual coating. Define what the trial proves and what remains unresolved.

The key distinction

The supplied product can differ in properties and handling requirements. Equipment cleanliness and residual test liquid also need an approved transition process. The manufacturer and equipment supplier should determine the appropriate product-specific qualification.

Practical checks

  1. State the purpose of the preliminary equipment trial.
  2. Record its limitations and the required next checks.
  3. Follow an approved preparation process before introducing the actual product.

Example

Illustrative example: a filler dispenses water consistently, so a buyer assumes its seals, dosing and changeover process are approved for a ceramic coating. Those additional questions still require review.

Scope and limits

Do not introduce coating into wet or unapproved equipment based on this guide. Use the exact supplier instructions and qualified equipment assessment.
