Jun 2, 2022 · Ex ‘m’ enclosure or component that has only component certificate (marked “U”) is not allowed to be installed in hazardous area unless it is part of an assembly of components in an equipment that has a full Ex certificate with the “X” and equipment label has full “Ex” marking including temperature class.

Basic concept: Ex n consists of several sub types of protection. In most cases being simplified versions of existing types of protection: Basic design is: safety by either limitation of radiation or protection of optical light. This type of protection is divided in:

Ex m is encapsulation that prevents the atmosphere reaching any potentially incendive parts. Ex n is similar to Ex m and means non-sparking which limits it to Zone 2, Category 3 environments. Ex ia or intrinsically safe is suitable for Zone 0 or 20, Category 1.

To comply with ATEX/IECEx regulations, all equipment and protective systems that are used in hazardous areas must be marked legibly and indelibly with a specific set of letters/numbers.

ATEX Notified Body (ExNB) Notified Bodies are appointed by governments of individual EU countries as responsible to carry out functions specified in the ATEX Equipment Directive, such as EU type examination of equipment and quality assurance assessment of equipment production. UK Approved Body (ExAB)

Oct 10, 2018 · ATEX and ex-proof classifications help manufacturers select and install equipment for potentially explosive atmospheres. ATEX is used in Europe, whereas Ex-Proof is used in North America and Canada. The process environment and properties of any materials that will be present need to be ascertained.

Ex m is either used as a component with trailing cables or more commonly in confunction with another protection method such as Ex em. ↩. 🔝.

Apr 3, 2021 · The encapsulation protection method (Ex m) is based on the segregation concept. This method is predominantly used in Europe and is recognized by all certifications agencies. Electrical parts that can be a source ignition are encapsulated in an epoxy resin.

Ex m Reasing Sealing. This is a type of protection based on a resin sealing of the electric parts that might ignite a dangerous mixture through sparking or overheating. It is generally used to protect solenoid valves and electronic circuits.
