Double acting pneumatic actuator manufacturer

Testing an ATEX electric actuator involves a series of rigorous assessments to ensure compliance with the ATEX Directive 2014/34/EU, which covers equipment intended for use in potentially explosive atmospheres. The ATEX certification process is designed to prevent the actuator from becoming a source of ignition in these hazardous environments. Here is an overview of the testing and certification process for ATEX electric actuators:

1. Quality Assurance of the Production Process: Manufacturers must operate an approved quality system for the production of ATEX electric actuators. This includes final product inspection and testing, as specified in Module D of the ATEX Directive. The quality system must ensure that each product complies with the type described in the EU-type examination certificate and satisfies the requirements of the ATEX Directive.

2. Surveillance: Notified bodies conduct periodic audits to ensure the manufacturer maintains and applies the quality system. Unexpected visits may also be paid to the manufacturer to carry out ATEX electric actuator tests or verify the quality system's effectiveness.

3. EU Declaration of Conformity: The manufacturer must draw up a written EU declaration of conformity for each product model, which confirms that the ATEX electric actuator complies with the essential health and safety requirements set out in Annex II of the ATEX Directive.

4. CE Marking: The CE marking must be affixed visibly, legibly, and indelibly to the product or its data plate, indicating that the product complies with the ATEX Directive.

5. Technical Documentation: Manufacturers must keep technical documentation available for assessment by the notified body. This documentation includes details of the design, manufacture, and operation of the actuator, as well as the results of tests conducted to demonstrate compliance with ATEX requirements.

6. ATEX Specific Markings: The ATEX electric actuator must bear specific markings of explosion protection, including the equipment group and category, as well as any other markings and information required by the ATEX Directive.

8. Performance Testing: ATEX electric Actuators must undergo performance tests to ensure they can operate effectively amidst constant vibration and shocks, which are common in off-highway equipment and other machinery.

9. Environmental Testing: Climatic tests, such as exposure to water, dust, high and low temperatures, and salt and chemical resistance, are conducted to ensure the ATEX electric actuator's reliability in harsh conditions.

10. Safety and Functional Testing: Tests are conducted to ensure that safety devices function independently and that the ATEX electric actuator meets the requirements for explosion protection, including the prevention of ignition sources.

11. Certification by Notified Bodies: After successful testing and verification, a notified body will issue a certificate of conformity, allowing the manufacturer to market the ATEX electric actuator as compliant with the ATEX Directive.

ATEX electric actuator is important to note that the specific tests and procedures can vary depending on the category and group of the equipment, as well as the nature of the explosive atmosphere it is designed to handle. Manufacturers must consult the relevant harmonised standards and work closely with notified bodies to ensure full compliance with the ATEX Directive.
