Certification Progress of Explosion Proof Equipment for Process Safety Purposes

27.04.2022

Flammable and explosive gases and dusts are used in many industrial sectors to ensure production continuity. It is a legal obligation for businesses that use explosive gases and dusts to make a ZONE (hazardous area) classification within the scope of the ATEX 153 Regulation (Safety and health protection of workers potentially at risk from explosive atmospheres). All equipment within the ZONE (hazardous area) resulting from the ZONE classification made must be explosionproof, certified according to the 2014/34/EU Regulation. The certification process of the explosion-proof equipment depends on group/category definition of the equipment, the relevant protection type standard, and its intended use.

Flame Arrestor Certification Progress

In the application stage manufacturer shall provide information about flame arrester types as end-of-line deflagration, in-line deflagration, pre-volume deflagration, in-line stable detonation, in-line unstable detonation and end-of-line stable detonation and gas groups as IIA1, IIA, IIB1, IIB2, IIB3, IIB, IIC and its size. Applicable test list is prepared in accordance with ISO 16852 standard requirements and contract is prepared by Notified Body. After contract is signed by parties, Manufacturer shall prepare technical file in accordance with 2014/34/EU ATEX directive. The file is examined by Notified Body in accordance with requirement of ATEX directive and relevant standards. After that manufacturer shall prepare a sample that conforms with information on the technical file. Sample will be examined by Notified Body. Standard tests will be applied to the sample. If it is successfully passed tests, all information regarding product and manufacturer will be uploaded to T.C. Ministry of Industry and Technology’s ONTEK system. QR code is assigned from the system for the certificate. Issued certificate with QR code is given to the manufacturer. [caption id="attachment_138747" align="aligncenter" width="689"]
