The objective of the IECEx System is to facilitate international trade in equipment and services used in explosive atmospheres by eliminating procedures of multiple national certification while consistently maintaining the necessary level of security.

General information on the Certification System of the International Electrotechnical Commission (IEC) in accordance with the requirements of standards applicable to equipment used in explosive atmospheres (IECEx System)

The basic principles of explosion safety are universal. They are based on the recommendations of the International Electrotechnical Commission (IEC). At the same time, there are different systems of compliance assessment of explosion-proof equipment in the world, like regional
(ATEX in Europe), national (GOST R in Russia, UL and FM in the United States, etc.), and international (IECEx).

The IECEx System is an international system of certification for compliance with the requirements of standards for electrical equipment for explosive atmospheres, which is created within the framework of the International Electrotechnical Commission (IEC, IEC) along with certification systems for electrical equipment (IEC CE, IECEE) and electronic components (IEC EC, IECQ).

The objective of the IECEx System is to facilitate international trade in equipment and services used in explosive atmospheres by eliminating procedures of multiple national certification while consistently maintaining the necessary level of security. This means reducing the cost of testing and certification for manufacturer and reducing the time of products to arrive to the market.

IECEx system was established in 1995. Currently member committees from 33 countries work within the framework of this System. Members of the IECEx System are Australia, Brazil, Canada, China, Croatia, the Czech Republic, Denmark, Finland, France, Germany, Hungary, India, Israel, Italy, Japan, Korea, Malaysia, the Netherlands, New Zealand, Norway, Poland, Romania, Russia, Singapore, Slovenia, South Africa, Sweden, Switzerland, Turkey, UK, USA, UAE.

The activity of certification system in accordance with the requirements of standards relating to equipment used in potentially explosive atmospheres (IECEx System) includes assessment and certification of equipment, workshops, staff competence and licensing of IECEx Conformity Mark application.

The following certification schemes operate in IECEx System:

  • IECEx equipment certification scheme (IECEx 02 Rules)
  • IECEx workshops certification scheme (IECEx 03 Rules)
  • IECEx personnel certification scheme ( IECEx 05 Rules) + Program of IECEx recognized training providers
  • IECEx conformity mark licensing scheme (IECEx 04 Rules)

Manufacturers of Ex-equipment and Ex-equipment workshops can apply for certification in the IECEx Certification Bodies (ExCB) in any country.
Countries and Certification Bodies can apply for membership in the IECEx Scheme in accordance with the procedures for the submission of applications. After accreditation in the Scheme, the Certification Bodies will have the right to issue IECEx Certificates.

Rules of the IECEx System including Procedure rules are posted free on the website of IEC.

National bodies-members of IEC System apply for their country's participation in the IEC system according to specific standards. The application is submitted to the Executive Secretary of the IECEx System.


WWBridge is cooperating with  a specialized center for certification of equipment for explosive atmospheres (Ex-equipment) and the only center in Russia and the member-countries of the Eurasian Economic Union accredited to carry out works on conformity assessment with international certification system IECEx scheme (since 2004).

Ensuring participation of the Russian Federation in the work of the IECEx System, in accordance with the orders of the Government of the Russian Federation No. 963-р dated July 17, 2001 and No. 526-р dated April 17, 2006 is vested in Rosstandart.

It has been accredited in the IECEX System s ince 2004 as certification body and testing laboratory of equipment for explosive atmospheres.

Test reports and quality assessment records issued in Russia are recognized by all bodies from 33 member-countries of IECEx System, in accordance with the requirements of IECEx 02 rules.

We can conduct testing and conformity assessment of Ex-equipment taking into account national specifics to obtain regional/national documents on conformity assessment on the basis of the IECEx test reports (ATEX for the European Union, UL for USA and Canada, a certificate of compliance for South Africa, China and other countries in the IECEx System.)

Certification experts in Russia will be pleased to consult you in your own language


Is the local representative company required for handling the EAC certification?
In accordance with the Customs Union legislation, a foreign manufacturer must have a Local representative company (an Applicant) on the territory of the Customs Union (CU) to issue the certificate/declaration. This means that an Applicant for you can be your customer, distributor or official representative company in CU. WorldWideBridge LLC will be mentioned on certificate/declaration as a local representative. 
What does Annual maintenance inspection assume?
Each serially producing product that requires Certificate of conformity is subjected to Annual Maintenance Inspection (or so-called Inspection control) in case of applying for more than 1-year certificate. It assumes that certification body which issued the CoC needs to confirm that the product is still produced at the same quality. It can be done through the re-testing or reviewing of Quality Management System documents. In some cases, the certification body can initiate a production site audits during AMI.
What does the cost of certification services depend on? Is there any price list?
The cost of certification services depends on the type of the required approval document and technical characteristics of the product itself that influences the scope of tests that are to be conducted. We have no price-list because used to work with a wide range of certification bodies, testing laboratories, and other specialized state institutions (Federal Security Service (FSS) licensing center, Radiofrequency center (RFC), Rostekhnadzor, Roszdravnadzor, etc.)And this means that the price can vary depending on product specification and certain certification body's pricing policy. If we are talking about the product specification, then the cost can be affected by the number of models, differences in applied models, the number of communication standards used (for radio products), the number of declared protective properties (for PPE), metrology characteristics ( for measuring devices) and so on. Each product is unique, each request must be carefully calculated to determine the type of document, the amount of testing, the most optimal certification scheme, the number of test reports, etc. Also, it is important to note that CU certification bodies have a certain accreditation (product range they can approve). So, in case of big projects that include different products for certification we should apply to several different authorities. Each of those has individual pricing policies due to their testing facilities. This fact can significantly affect the pricing and process. Our goal is to provide accurate consulting services in a specific case. Therefore, we are happy to evaluate the client's application, which contains the name and description of the product and the HS code (Customs code).
What is the EAC mark and when should it be applied?
EAC mark is an approval sign for products that are needed to be imported to the Customs Union (CU). This mark gives the opportunity to enter the markets of Russia, Belarus, Kazakstan, Armenia and Kyrgyzstan, distribute products throughout the entire territory of these countries, and extend your audience to almost 200 millions of people. EAC mark can be obtained only after the certification procedure according to the Technical Regulations of the Customs union is finished. ЕАС abbreviation stands for “Eurasian Conformity”. The unified mark is applied to each unit of production, packaging or accompanying documentation. The image of the unified mark has to be one colour and contrast with the surface colour on which it is applied. The place of application of the unified mark on the product, packaging and documentation is established in technical regulations of the Customs union.
Can the production site audit be replaced by CIG report?
The production site audit can be required in case the product requires the Certificate of conformity to the Technical Regulation of the Customs union. A lot of our clients are interested whether the production audit can be replaced by CIG report that use to be issued by most European producers. Customs union approval procedure does not assume replacing of the audit by providing CIG report because the expert from certification authority is obliged to check the QMS personally according to our law.
How is determine whether the Declaration of conformity or Certificate of conformity is required?
The necessary form of the approval document depends on the product description and HS code (Customs code). In each technical regulations of the Customs union, there is the List which determines whether Certificate of conformity or Declaration of conformity is required for certain product according to its HS Code and application field. In some cases, technical parameters must be also taken into consideration (for pressure equipment, PPE products, etc.).
What is required to import the samples for tests?
The samples can be imported for test only after all the preparations. Firstly, we should prepare the application for the certification and confirm it with the client.  On the second stage, the client s preparing the invoice for samples delivery that is needed to be sent to us for the check.  When the samples arrived at the customs clearance office the receiver prepare all the necessary documents confirming the import purpose and pay all the required fees to the government.  Import fees depend on the announced product price according to the shipping invoice. Products that are valued less than 200 EUR are free from such fees.  The final stage assumes the registration of the cargo declaration that confirms that the samples passed the customs clearance and can be used on for certification.
How can the EAC approval documents be prolonged after the expiration date?
Customs union certification system does not assume the prolongation procedure. This means that the certification process must be repeated including tests, production site audit if required. After all the procedures are done you will receive a new approval document. 
Is there an open register where the issued EAC approval document can be checked?
Almost all approval documents are to be registered in the open registers. Here you can refer to some of them: the Registered EAC Certificates of Conformity ,  the Registered EAC Declarations of Conformity , the registered State Registration Certificates , FFS Notifications (encrypted means) register.  If you need additional information please apply to [email protected]
