"No public information" means we searched as of the date shown and found no public evidence. This is not a statement about actual conformity — evidence we do not hold may well exist. Documented evidence only covers its own scope: FCC Part 15B is a US EMC record and replaces neither the EU declaration of conformity nor EN-based EMC testing or a Radio Equipment Directive assessment.
Explosion protection
| Approval | to be added |
|---|
An Ex approval always applies to one specific combination of zone, gas group and temperature class. Without those three it says nothing about whether the machine may be used in your area. Gas detection is not an Ex approval.
Market and availability
