Time：
2026-04-03
Jiayu Testing is committed to providing explosion-proof product certification services to ensure that products meet relevant regulatory requirements.
Dangerous place "refers to an environment that contains (or may contain) flammable gases, dust, or fibers, and the concentration of these substances may reach flammable levels. There are sources of fire or heat in the environment that are sufficient to cause an explosion. The ignition source may be gas, steam, liquid, or dust.
Classification criteria for hazardous areas:
▪ Types of volatile substances present
▪ The likelihood of volatile substances appearing at a given time
The HazLoc certification for explosion-proof products indicates that the product has met the minimum safety standards and can be safely used in designated hazardous areas that have been evaluated. This article summarizes the requirements for explosion-proof product North American certification, explosion-proof product IECEx certification, explosion-proof product ATEX certification, and explosion-proof product UKCA certification.
Global explosion-proof certification requirements
The certification process for electrical products designed and manufactured for hazardous locations is extremely strict due to the risk of explosion.
1. North American certificate:
The hazardous location certificate in North America allows electrical equipment to be installed in classified areas (hazardous locations) within the North American market. This type of environment can be classified through a partition system or a category/classification system.
To obtain a North American hazardous location certificate, electrical equipment must comply with the following aspects:
The general safety requirements for this type of equipment, also known as common site requirements
Standards specifically applicable to explosion-proof products, including category/grading markings, zoning markings, or two markings
The requirements for ordinary places include general safety requirements, such as:
risk of electric shock
Fire risk
risk of injury
The standards applicable to different types of electrical equipment in ordinary places are also different. In some cases, testing for both regular and hazardous locations may be conducted simultaneously.
During the certification process, the manufacturing enterprise is required to submit:
Product Documentation
sample
2. IECEx certificate:
IECEx is the abbreviation for the International Electrotechnical Commission's certification system for explosion-proof electrical products. It is an international certification program for explosion-proof equipment or components, and the goal of the IECEx system is to promote international trade in explosion-proof equipment and services.
According to a series of qualification assessment schemes, IECEx can ensure that the equipment, services, and personnel covered by the IECEx certificate meet the requirements of relevant standards.
The goal of the IECEx system is to promote international trade in explosion-proof equipment and services. The IECEx certificate is an international certificate, therefore it helps to:
Reduce testing costs
Reduce certification costs
Shorten the time to enter the market
Winning confidence in devices and services globally
Promote products globally through the IECEx website
To support the IECEx certification, continuous monitoring activities (QAR) will be carried out after the issuance of equipment/component certificates.
The IECEx certification system involves two different reports during the certification process:
a. IECEx Technical Report (ExTR)
b. IECEx Quality Assessment Report (QAR)
If these two reports prove that the product meets the requirements, two main steps need to be completed before providing the IECEx Certificate of Conformity (CofC) for electrical equipment.
1) Technical evaluation
Evaluate and test representative samples of the product to ensure compliance with all requirements of explosion-proof IEC or ISO standards (60079 xx series standards for electrical equipment, 80079 xx series standards for non electrical equipment).
General safety ("ordinary premises") requirements can be self declared; It is not included in the IECEx program. But if necessary, it can represent the production enterprise to conduct testing and evaluation, and generate corresponding evaluation reports.
IECEx Technical Evaluation Reports (ExTRs) are used to record test results and engineering evaluation results, including a list of supporting documents (drawing packages or planned drawings). If there are any changes or updates to the product, the technical evaluation report will be used as the basis for future evaluations.
2) Quality assessment
If the product does not have a quality assessment report number, an initial supervision audit will be conducted. All places where products are produced must be audited to confirm that they can produce products with the same design and performance as the test samples. In other words, the existing quality system must ensure that products always comply with the types described in ExTRs.
3. ATEX certificate:
ATEX stands for ATmosph è res EXplosibles, which is the regulatory framework in Europe for the manufacture, sale, and use of equipment in potentially explosive environments within the European Union.
ATEX is adopted in the EU Directive 2014/34/EU, known as the ATEX Directive, which covers equipment and protective systems used in potentially explosive environments. This directive is consistent with the new legislative framework policy and came into effect on April 20, 2016, replacing the previous Directive 94/9/EC.
Electrical equipment must meet the basic health and safety requirements of the ATEX directive and undergo a conformity assessment process before being placed on the EU market. Electrical equipment must bear the CE mark.
There are two types of ATEX certificates:
a) EU formal inspection and certification
Class 1 and Class 2 devices must require the participation of certification bodies, including:
Class 1 equipment: Electrical or non electrical equipment (with the strictest requirements)
Class 2 equipment: Electrical equipment or internal combustion engines
Before obtaining the EU formal certification certificate, it is necessary to evaluate and test according to the European Harmonized Standards, which include standards published by the European Committee for Electrotechnical Standardization and listed in the EU Official Journal, ATEX Directive, and all relevant Essential Health and Safety Requirements (EHSR).
The ATEX certification system is applicable to Class 1 and Class 2 equipment, and involves two different reports during the certification process: a technical evaluation report; Quality Assurance Notice (QAN).
Production enterprises must comply with the appropriate annexes applicable to the category of directives (IV, V, VI, VII or IX), regardless of whether they comply with the quality management system of ISO 9001.
Audit all production sites involved in the product manufacturing process. Audit usually includes reviewing records and inspecting the design specifications of equipment.
The ATEX quality assurance process typically takes one day and is conducted approximately every 18 months (or every 12 months if ISO 9001 certification is not obtained). A new ATEX quality assurance notification certificate is issued every 3 years.
The EU formal inspection certificate will only be issued after verifying compliance with all requirements. Production enterprises are required to provide a declaration of compliance with the standards.
b) Formal authentication
This certificate is applicable to Class 2 non electrical products and all Class 3 products, respectively for installation and/or use in Zone 1 or Zone 2.
For the three types of products, the quality system assessment can be completed by the production enterprise, but the production enterprise retains relevant documents. For Class 2 non electrical equipment, there is an additional requirement that technical documents must be stored at the ATEX certification body.
Product evaluation can be conducted according to the requirements of the manufacturing enterprise and a formal certification certificate can be issued. Still need to comply with all applicable standards!
We provide ATEX certification services for all three types of products. When the product is certified to comply with the ATEX directive, we can complete and issue a QAN to ensure that you can declare that the product fully complies with the directive and bring it to market..
4. UKCA certificate:
Affected by Brexit, the UK will adopt new product labeling regulations, requiring all products launched in the UK to use the UK Certificate of Conformity (UKCA), replacing the EU CE mark. After January 1, 2023, products sold in the UK market must obtain the UKCA logo.
UKCA certification complies with UK law (UKSI 2016:1107). As described below, UKCA's requirements reflect ATEX's requirements from these aspects.
Appendix 1- Basic Health and Safety
This annex basically reflects the requirements of the ATEX Directive (2014/34/EU).
Appendix 2- Certification Body Requirements
This annex is similar to Article 21 of the ATEX Directive.
Appendix 3- Operational Obligations of Certification Bodies
This annex is similar to Articles 29 and 30 of the ATEX Directive.
Schedule 4-1974 specifies the enforcement powers of the Health and Safety Executive Committee and the Office of Nuclear Regulation.
Appendix 5- Compliance, Revocation, and Recall Notices
Appendix 6- Declaration of Conformity to Standards in the UK
Most products that comply with legal requirements and bear the UKCA logo require a UK conformity declaration. The statement should:
Declare that the product complies with the relevant legal requirements applicable to that specific product
Including the name and address of the manufacturing enterprise (or authorized representative), as well as information about the product and the conformity assessment agency (if relevant)
Generally speaking, the required information in the conformity declaration is the same as that in the current EU conformity declaration.
When applying for a UKCA certificate, the following content can provide corresponding support:
Valid EU formal inspection certificate and/or IECEx certificate of conformity
Effective ATEX report and/or IECEx test report
Effective ATEX Quality Assurance Certificate (QAN) and audit reports required during the certification period
Valid ATEX Annex V or Annex VI certificate and accompanying report
