1、 Introduction to IECEx System

The International Electrotechnical Commission (IECEx) is an organization that provides standard certification for electrical equipment used in explosive environments. Its full English name is IEC System for Certification to Standards for Electrical Equipment for Explosive Atmospheres, abbreviated as IECEx System

The IECEx system is an international organization dedicated to the safety certification of explosion-proof electrical products (referred to as Ex products) under the International Electrotechnical Commission.

2、 The objectives of the IECEx system

The ultimate goal of the IECEx system is to achieve worldwide acceptance of:

A Standard - Relevant Standards Designated by IEC TC31 Technical Committee
One certificate - IECEx Certification of Conformity
A logo——IECEx Mark of Conformity

3、 The goal of IECEx product certification is:

The international certification of Ex products according to international standards aims to ensure a moderate level of safety for explosion-proof electrical products while:
1. Reduce certification costs for manufacturers and time to market

2. Maintain international standards in the product evaluation process

3. Include in an international database

4. Maintain equipment and services under IECEx certification to meet international standards
