9. Repairs
In order to ensure the proper functioning of the installation
under normal operating conditions, it is recommended to
replace the device before 10 years have elapsed since the
date of manufacture.
The 10 years is a recommendation that can be replaced by
national laws or technical regulators, taking into account the
operating conditions of integrated safety devices and
maintenance schedules.
According to DGUV 79:
The Contractor must ensure that parts of consumable
equipment that are subject to wear and aging are replaced
after a maximum of 8 years. This does not apply if the proper
condition has been confirmed by an expert.
