Quick Answer
Quick Answer
An ATEX Declaration of Conformity is a manufacturer-issued document confirming that a product complies with ATEX Directive 2014/34/EU and other applicable European requirements. The document supports CE marking and serves as an official statement of regulatory compliance.
What Is a Declaration of Conformity?
A Declaration of Conformity, often called a DoC, is a legal document in which a manufacturer declares that a product satisfies all applicable regulatory requirements.
Within the ATEX framework, the declaration confirms that the equipment complies with ATEX Directive 2014/34/EU and has successfully completed the required conformity assessment procedures.
The declaration is issued by the manufacturer rather than the Notified Body.
This distinction is important because responsibility for compliance ultimately remains with the manufacturer.
Why Is the Declaration Important?
The Declaration of Conformity provides formal evidence that the manufacturer has assessed the product against applicable requirements and believes the equipment satisfies those obligations.
The document supports:
- Regulatory compliance
- CE marking requirements
- Market access within the European Union
- Procurement verification activities
- Inspection and audit programs
- Technical file documentation
Many end users require a copy of the Declaration of Conformity before accepting hazardous area equipment deliveries.
Who Issues the Declaration?
The Declaration of Conformity is issued and signed by the manufacturer or an authorized representative acting on behalf of the manufacturer.
Even where a Notified Body participates in certification activities, the Declaration of Conformity remains a manufacturer-issued document.
The manufacturer therefore accepts responsibility for ensuring that the product complies with all applicable legislation.
When Is a Declaration of Conformity Required?
A Declaration of Conformity is generally required whenever equipment subject to ATEX Directive 2014/34/EU is placed on the European market.
The declaration supports the application of CE marking and demonstrates completion of the appropriate conformity assessment procedures.
Without the required documentation, equipment may not legally be placed on the European market.
Information Included in an ATEX Declaration of Conformity
ATEX Declarations of Conformity follow a structured format and contain key information needed to identify the equipment and verify compliance with applicable legislation.
Although document layouts may vary between manufacturers, the content requirements are generally similar.
| Typical Information | Description |
|---|---|
| Manufacturer Name | Legal entity responsible for the product |
| Manufacturer Address | Official business address |
| Product Description | Identification of the equipment |
| Model Number | Product type designation |
| Applicable Directives | Relevant European legislation |
| Applied Standards | Harmonized standards used for compliance |
| Notified Body Information | Where applicable |
| Authorized Signature | Manufacturer representative |
| Date of Issue | Declaration issue date |
This information allows regulators, inspectors, and end users to trace the compliance basis of the equipment.
Typical Declaration Structure
A Declaration of Conformity commonly contains the following elements:
- Manufacturer identification
- Unique product identification
- Statement of conformity
- Applicable directives
- Applicable harmonized standards
- Notified Body details where relevant
- Authorized signature
- Date and location of issue
The exact format may vary between manufacturers provided the required information is included.
Relationship Between the Declaration and CE Marking
The Declaration of Conformity and CE marking are closely related.
Before applying the CE mark, the manufacturer must complete the applicable conformity assessment procedures and prepare the required Declaration of Conformity.
The declaration provides documentary evidence supporting the manufacturer's decision to apply CE marking.
For ATEX equipment, the Declaration of Conformity serves as one of the key compliance documents supporting market access within the European Union.
Relationship Between the Declaration and EU-Type Examination Certificates
An EU-Type Examination Certificate and a Declaration of Conformity are not the same document.
| Document | Issued By | Purpose |
|---|---|---|
| EU-Type Examination Certificate | ATEX Notified Body | Confirms product design assessment |
| Declaration of Conformity | Manufacturer | Declares compliance and assumes responsibility |
The manufacturer may reference the EU-Type Examination Certificate within the Declaration of Conformity where applicable.
Together, the two documents form part of the overall conformity assessment framework.
Relationship Between the Declaration and ATEX Notified Bodies
Notified Bodies may participate in certification activities for certain equipment categories and conformity assessment modules.
However, the Declaration of Conformity remains a manufacturer-issued document even when a Notified Body has been involved.
The manufacturer's responsibility for compliance does not transfer to the Notified Body.
This distinction is a fundamental principle of European product legislation.
Applicable Directives Commonly Listed
Many hazardous area products are subject to more than one European directive.
As a result, a Declaration of Conformity may reference multiple directives.
| Directive | Purpose |
|---|---|
| 2014/34/EU | ATEX Equipment Directive |
| 2014/30/EU | Electromagnetic Compatibility (EMC) |
| 2014/35/EU | Low Voltage Directive (LVD) |
| 2011/65/EU | RoHS Directive |
| 2014/53/EU | Radio Equipment Directive (where applicable) |
The declaration should identify all applicable legislation relevant to the product.
Common Errors Found in Declarations
During audits and procurement reviews, several common issues are frequently identified.
- Incorrect product identification
- Outdated directive references
- Missing harmonized standards
- Missing signature authorization
- Incorrect Notified Body references
- Inconsistent equipment markings
- Failure to update revised product models
Manufacturers should periodically review declarations to ensure continued accuracy and regulatory compliance.
Manufacturer Responsibilities
By issuing a Declaration of Conformity, the manufacturer formally accepts responsibility for product compliance.
This responsibility includes:
- Maintaining technical documentation
- Supporting conformity assessment records
- Ensuring production consistency
- Managing design changes
- Retaining compliance evidence
- Providing documentation upon request
Failure to meet these obligations may result in regulatory action or restrictions on market access.
Common Misunderstandings About ATEX Declarations of Conformity
Declarations of Conformity are among the most frequently requested compliance documents for hazardous area equipment. However, their purpose and legal significance are often misunderstood.
The Declaration Is the Same as an ATEX Certificate
No. A Declaration of Conformity is issued by the manufacturer, whereas ATEX certificates are issued by a Notified Body where applicable. The declaration confirms compliance and identifies the manufacturer as the responsible party.
A Declaration of Conformity Replaces Technical Documentation
No. The declaration is only one part of the compliance framework. Manufacturers must also maintain technical files, test reports, certification records, risk assessments, and other supporting documentation.
The Notified Body Issues the Declaration
No. The declaration is always issued by the manufacturer or an authorized representative. Even when a Notified Body participates in certification activities, responsibility for the declaration remains with the manufacturer.
CE Marking Is Sufficient Without a Declaration
