Protection Levels (EPL’s) are the IEC’s equivalent of the Levels of Protection ATEX categories. The EPL’s follow the level of protection indication of a, b and c in line with the level of protection afforded by the equipment. There are eight equipment protection levels these are: Table 6: Equipment Protection Levels: Definitions

I started with the concept of metamorphosis in mind, says architect Sebastian Irarrazaval of The concept is much the same for electronics; for example, an electrical circuit can be easily damaged or destroyed if introduced to water or high humidity levels. fire protection rules as well as nuclear specific rules.

Types of protection indicates the level of protection concepts the equipment is designed for. The protection concepts are divided in to sub classes. Encapsulated. Protection applied by encasing the components in a resin type material. The protection is referred to as "Ex m". Sub divisions ma for Zone 0 and mb for Zone 1 PDF Download.

There are four basic methods utilised to avoid uncontrolled ignitions - exclusion of the flammable substance, prevention of component sparks or hot surfaces, explosion quenching and energy limitation.

ATEX Directive 94/9 EC Principal protection measures. Electrical Equipment There are eight recognised concepts of explosion protection within Europe.

Ex i Intrinsic Safety is an explosion protection concept in which the electrical energy within the equipment is restricted to a level which is below that what may cause an ignition or to limit the heating of the surface of the hazardous area equipment. ATEX 137 (operator guideline) defines the operator's responsibility The explosion protection guideline 1999/92/EC (generally known as ATEX 137) contains basic safety requirements concerning hazards from "explosive atmospheres". Directive 1999/92/EC (PDF) > ATEX 137 (operator guidelines) Details. Occupational safety is an important subject. The Flameproof ATEX protection concept is providing a strong and closely fitting enclosure to protect its contents.

If you talk about explosion protection, you are very likely to hear the term Atex introduced the concept of Categories and Equipment Protection Levels (EPL), partly as an attempt to simplify equipment selection. The are 6 Atex Categories, designated ' 1 ', ' 2 ' and ' 3 ' representing levels of Risk ' High ' ' Medium ' and ' Low ' respectively each with either ' G ' and ' D ' for Gas and Dust. In Europe explosion-protected equipment is classified into cate- gories by EU Directive 2014/34 (ATEX). At international level the equipment protection level (EPL) was introduced by IEC 60079 in 2007.

EPLs and ATEX The use of the EPLs comes from a realisation in the international field that the ATEX Directive did get something right in principle. As more and more equipment is provided with complicated combinations of protection concepts, a single identifier is needed of the level of protection that can be assumed for that equipment.
