ATEX Certification Application Process

Step 1. Determine Certification Requirements

Companies must first evaluate whether their products require ATEX certification and determine:

• Applicable ATEX classification (e.g., Ex d, Ex e, Ex i)

• Relevant ATEX directive (2014/34/EU)

Step 2. Select a Qualified Certification Body

The product must be certified by an EU-recognized Notified Body. STS has long-term partnerships with multiple EU ATEX Notified Bodies, including TÜV, CSA, TI, ECM, and can provide full certification support.

Step 3. Prepare Technical Documentation

Technical documentation is critical for ATEX certification. Required materials typically include:

• Design and Drawing Data: Electrical schematics, structural drawings, assembly diagrams, exploded-view drawings, bills of materials (BOM)

• Technical Data: User manuals, technical specifications

• Process Documents and Test Reports: Encapsulation procedures, battery specifications, wireless emission power, laser safety reports, etc.

• Production Control Documents: Quality management and production control measures demonstrating compliance with ATEX standards

Step 4. Submit Application and Pay Fees

Submit the prepared documentation to the selected Notified Body and pay the associated fees, which depend on the product complexity and certification requirements.

Step 5. Technical Assessment and Testing

The Notified Body will perform:

• Design evaluations

• Explosion-proof performance testing

• Safety and functional testing relevant to the product type

Step 6. Factory Audit (If Applicable)

For certain product types, on-site audits may be conducted to verify:

• Production equipment and processes

• Quality control systems

• Manufacturing consistency and compliance

Step 7. Comprehensive Evaluation and Certificate Issuance

After document review, product testing, and any factory audits, a comprehensive evaluation is conducted. Upon passing, the company receives:

• ATEX explosion-proof certification

• Corresponding conformity marking (CE marking)

ATEX Certification Standards

ATEX certification is based on the EN 60079 series, which covers different explosion protection methods and their testing requirements:

• EN 60079-1: Flameproof equipment (Ex d)

• EN 60079-7: Increased safety equipment (Ex e)

• EN 60079-11: Intrinsically safe equipment (Ex i)

Other standards in the series apply to specific protection types such as pressurized, powder, or encapsulated equipment. Compliance with these standards ensures that equipment can safely operate in hazardous locations.
