What is EN 405:2012?

EN 405:2012 is a European standard that specifies the requirements for respiratory protective devices used in self-contained open-circuit compressed air breathing apparatus with full face mask. It describes the essential performance characteristics of the equipment and sets out the testing methods to ensure they meet the required standards.

Features and Benefits of EN 405:2012

EN 405:2012 provides several features and benefits that make it an essential standard for respiratory protective devices.

Firstly, it ensures that the equipment provides reliable protection against harmful substances in the air. This is achieved through rigorous testing procedures, including measuring the inward leakage of contaminants and assessing the filtration efficiency of the device.

Secondly, EN 405:2012 sets requirements for the compatibility and interchangeability of parts, such as filters and visors. This makes it easier for users to replace and upgrade components, ensuring the longevity of the equipment.

Furthermore, it establishes guidelines on the ergonomic design of the apparatus, aiming to provide comfort and ease of use for the wearer. Features like adjustable straps and harnesses are taken into consideration in order to create a personalized fit, reducing strain and discomfort during prolonged use.

Compliance and Certification

In order for manufacturers to claim compliance with EN 405:2012, their products must undergo extensive testing performed by accredited laboratories. These tests evaluate the performance and durability of the equipment according to the specified criteria.

There are also independent certification bodies that verify compliance with the standard, providing additional assurance to end-users. The certification process involves audits of the manufacturer's production facilities, assessment of quality management systems, and review of technical documentation.

It is important for users to look for the CE mark on the equipment, as it signifies compliance with EU regulations and standards, including EN 405:2012. This mark indicates that the product meets the essential health and safety requirements set out by relevant directives.

Conclusion

EN 405:2012 plays a crucial role in ensuring the effectiveness and reliability of respiratory protective devices used in hazardous environments. Compliance with this standard provides users with the confidence that their equipment meets the necessary requirements to protect them against harmful substances in the air.

By adhering to EN 405:2012, manufacturers can demonstrate their commitment to producing high-quality products and providing a safe working environment for users.
