Hazard class Denotes type of protection (see protection concepts for alternatives) Se hela listan på straightpoint.com I.S. is a protection concept based around limiting the available electrical energy to nonincendive levels so that sparks cannot occur from short circuit or failures which could cause an explosive atmosphere to ignite.

Equipment for explosive atmospheres (ATEX) Base: Directive 2014/34/EU of the European Parliament and of the Council of 26 February 2014 on the harmonisation of the laws of the Member States relating to equipment and protective systems intended for use in potentially explosive atmospheres (recast).

There are eight equipment protection levels these are: Table 6: Equipment Protection … ATEX Concepts - DSEAR on site assessment and evaluation, area classification, explosion protection documents and site audits, ATEX equipment certification and approvals, DSEAR and ATEX Training - UK DSEAR experts - Dangerous Substances - ATEX 14/34/EU - … ATEX Area Classifications/Zoning Definitions. The protection concepts employed are usually a combination of Ex d equipment such as flameproof fan motors etc and intrinsically safe equipment. The Ex i concept includes for devices mounted in the main control panel in the safe area. 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.

ATEX Concepts – Intrinsically Safety – Apparatus or System Europe, NEC 500 and NEC505 A protection technique based upon the restriction of electrical energy within the apparatus and in the interconnecting wiring, exposed to a explosive atmosphere, to a level below that which can cause ignition by either sparking or heating effects.
