Inspection

1. Material Tests

In addition to the quality control tests that the Manufacturer will have in place for compounds and materials listed in the following table, the following Material Tests should be conducted every three months.

2. Adhesion Tests

The adhesion strength between all composite plies of the hose Body will be determined by peel testing in accordance with ISO 36 using strip test pieces.
The measured adhesion strength will be not less than 6 N/mm.

3. Buoyancy Recovery Test

Adhesion tests will also be conducted on the integral buoyancy medium at three monthly intervals.
The sample will have a minimum internal diameter of 300 mm and will be at least 500 mm long.
