Service life (for centrifuges according to Machinery Directive)
The rotors and accessories have a limited service life.
WARNING
• Perform regular checks (at least once per month) for safety reasons!
• Pay special attention to changes, such as corrosion, cracks, material
abrasion, etc.
• After 10 years, they must be inspected by the manufacturer.
• After 50,000 cycles, the rotor must be scrapped for reasons of safety.
• If other data concerning the service life are engraved on the rotor or
bucket, these data shall apply accordingly. For example, a bucket with
the engraving "max. cycles = 10,000" has a service life of 10,000
cycles, and a rotor with the engraving "Exp. date 01/27" must be
scrapped in January 2027 at the latest (see figure).
• If a specification concerning the maximum number of cycles
and
a
specification concerning the service life (i.e. a date) are provided, the
specification that occurs first shall apply.
