AUMA Actuators Pass Corrosion Certification

A new TÜV certificate confirms that AUMA’s electric actuators have passed the most demanding corrosion protection tests and meet the requirements of EN ISO 12944-6 for corrosivity categories C5-M long (marine, coastal and offshore areas) and C5-I long (industrial areas with high humidity and aggressive atmospheres).

To achieve this C5-M certification, the products had to undergo a salt mist test (EN ISO 9227:2012) for 1,500 hours and a constant humidity test with condensation (EN ISO 6270-2:2005) for 720 hours. For C5-I certification, the devices had to additionally withstand 30 cycles of a condensation alternating climate test containing sulfur dioxide (EN ISO 3231).
