Case 3

Maintenance and Diagnostics

Periodic cleaning using a  mild detergent or non-etching cleaning compound should be carried out ideally twice annually. The cleaning should be done from top down, with sufficient rinsing and drying after the cleaning. Cleaning should be uniform and localised excessive abrasive rubbing should be avoided. Light abrasive cleaning using compound with mild abrasive action is recommended every two to three years followed by sealing with protectant coat.

Maintenance

Inspections should be carried out to look out for signs of deterioration in aluminium framing in accordance with BS EN 13830, SS 654 or equivalent. Routine cleaning should be carried out to remove surface contaminants from metals in order to ensure maximum corrosion resistance of the metal. The
cleaning process chosen should be selected based on the type of contaminant, the recommended degree
of cleanliness, and cost in accordance with ASTM A380/A380M-17, BS EN 1993-1-4, BS EN ISO 12944-8 or equivalent. Special care should be taken in order not to damage the cladding surface during cleaning/maintenance.

Diagnostics of Defect (see also NDT)

1. Visual Inspection to identify the defect.
2. The thickness of the coating can be measured with the ISOSCOPE MPO.
3. An eddy current instrument can used to identify corrosion.
4. Gloss meter to measure the glossiness.
