10.5.8 Visual inspection for leakage, cracking, force effects and corrosion
External inspection is visual inspection and needs to be carried out at least
semi-annually (or more often depending on operating conditions and use).
Clean the system before visual inspection as necessary.
Visual inspection is carried out for:
• Leakage
• Cracking
• Corrosion
• Dents due to external force effects
In case of leakage at screwed-in components, these must be tightened with the
appropriate torque and documented. If leakage still occurs at this position, the
contact must be thoroughly checked for the cause of leakage. Depending on the
result, seals and/or the component must be replaced.
In case of cracking and resulting leakage, the cause must be identified and corrected.
Afterwards, affected components must be replaced or thoroughly repaired.
In case of indications of external force effects, the cause must be identified and
corrected. Afterwards, the component and enclosing components must be checked
for damage and assessed for further reliable use.
As required, these components are to be replaced or thoroughly repaired.
In case of indications of corrosion, the component must be checked for damage and
assessed for further reliable use. As required, this component is to be replaced or
thoroughly repaired. In any case, corrosion protection must be ensured.
