3.14 Reference test and annual periodic re-test for protein-based alcohol-resistant foam concentrates

 Protein-based alcohol-resistant foam concentrates should be required to demonstrate manufacturing consistency through an annual small-scale test at a recognized test laboratory. The reference test should be performed at the same time and at the same recognized laboratory as the full-scale test defined in subsection 3.9.

The concentrate should be tested according to standards ISO 7203-3 Annex C, EN 1568-4 Annex I, SP Method 2580 or another standard acceptable to the Administration. The reference test and annual test should be carried out to the same standard.

The concentrate is deemed to fail the test if the results from the annual small scale test indicate significant changes in the foam quality compared to the reference test.
