2.1 Explosion Protection Standards that
CENTUM has Acquired
There are various standards for explosion protection in each region. Therefore, when equipment
tries to be used in a certain region, the equipment needs to be an approved product with
explosion protection standards adopted in the region. CENTUM, a global product, has complied
the standards adopted in North America and Europe.
The table below lists the explosion protection standards that CENTUM complies and their
approval authorities. This chapter mainly describes the explosion protection compliance of
