What is ex N protection?
Ex n or Reduced Risk protection is a standard of explosion protection applied to electrical equipment used in hazardous areas such that, in normal operating circumstances and in certain specified abnormal conditions, for example a hazardous area light fitting with a failed lamp, it is not capable of igniting a …
What does ATEX approved mean?
If a product / piece of equipment has official ATEX certification, it has been fully tested and approved to be safe to use in hazardous / explosive atmospheres.
What is the difference between Ex and ATEX?
Although there are some small differences between each certification, ATEX and IEC Ex are very similar. The main difference is the geographical location where the certification is recognised and accepted. While ATEX is a requirement in Europe, IEC Ex is accepted across several countries internationally.
What is increased safety Ex e?
Increased Safety Ex e is an explosion protection concept applied to the installation to ensure increased security against the possibility of excessive temperatures and sparks from hazardous area electrical equipment. Equipment that normally causes sparks is excluded from use within this method of explosion protection.
What is the difference between EXE and EXD?
It’s easy to think of Exe enclosures and Exd enclosures as both being explosion proof, but the different designations have slightly different meanings. Exe enclosures are deemed ‘explosion protected’ but not necessarily ‘flame proof’ Exd enclosures are ‘flame proof’ which means they should contain an explosion.
What is the difference between Dsear and ATEX?
DSEAR is for the assessment of a dangerous substance (gas, liquid, dust etc.) and ATEX provides guidance on the type of equipment you should use in each area once you have classified them as the result of an assessment.
What is ATEX Group II?
ATEX equipment group II: Equipment in this category is intended for use in areas in which explosive atmospheres caused by gases, vapours, mists or air/dust mixtures are likely to occur occasionally.
What is the difference between ATEX and explosion proof?
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.
What is ATEX zone2?
ATEX Zone 2 definition – What is Zone 2? The definition of Zone 2 is a hazardous area classified as an atmosphere where a mixture of air and flammable substances in the form of gas, vapour or mist is not likely to occur in normal operation, but if it does occur, will persist for a short period only.
What are the protection concepts for IECEX and ATEX?
The table below lists the types of protection methods and basic concepts of protection according to ATEX and IECEx standards for electrical equipment that is to be operated or installed in hazardous areas. The matrix is constructed to enable the fast cross referencing of protection concepts for zones and related equipment protection levels.
Can you use ATEX as an alternative to s?
The use of EPL and ATEX Category directly is an alternative for “s” marking. The IEC standard EN 60079-33 is made public and is expected to become effective soon, so that the normal Ex certification will also be possible for Ex-s Zone depending upon Manufacturers Certification.
What are the different types of EPL protection?
The IEC standard EN 60079-33 is made public and is expected to become effective soon, so that the normal Ex certification will also be possible for Ex-s Zone depending upon Manufacturers Certification. The types of protection are subdivided into several sub classes, linked to EPL: ma and mb, px, py and pz, ia, ib and ic.
