On filling lines, we perform two types of tests – an integrity test (crack test) and a dye/shadow test to verify the correct setup of the cleaning process.
The filling line must be clean, dry, and degreased before the test.
The penetration test of the filling line consists of applying a special penetrant solution to the inner space and subsequently performing a comprehensive inspection. We essentially look for all areas where the penetrant adheres or leaks, such as cracks, deep pores, weld damage, or other serious defects.
We do not look for areas where the penetrant does not adhere or leak, since in this case it is not considered serious material damage. Such surface imperfections may be present in larger quantities, for example dimples, scratches, or surface corrosion without significant material deformation.
After spraying the filling line with penetrant, the solution is left to act for the necessary time (usually approx. 30–45 minutes). This is followed by rinsing with water and drying.
The actual detection of the filling line is carried out by a detailed inspection of the material surface under UV light.
An integral part of our test is photo documentation. Findings are photographed both under UV and normal light. The minimum scope of documentation includes a photo of the line and photos of its individual parts.
The dye test of the filling line consists of penetrating the internal space with a special penetrant solution followed by a comprehensive inspection. We mainly look for all areas where the cleaning system works insufficiently, which is indicated by residual penetrant on the surface of the filling line. This test does not include diagnostics of damaged areas.
After spraying the line with the penetrant, the substance is left to act for the necessary time (usually about 30–45 minutes). The line's cleaning program is then restarted, and after completion, the results are evaluated under UV light.
