EN 12083:1998

Overview

EN 12083:1998 is a key European Standard developed by CEN that governs respiratory protective devices equipped with filters connected via breathing hoses, specifically non-mask mounted filters. This standard defines the requirements, testing procedures, and marking criteria for particle filters, gas filters, and combined filters used in unassisted respiratory protection systems. It excludes escape apparatus and filtering facepieces, focusing instead on filters that are standalone components worn by users.

The standard ensures the reliability and safety of these respiratory filters through rigorous laboratory and practical performance tests. By adhering to EN 12083:1998, manufacturers and users can be confident in the protective capabilities of their respiratory devices in various hazardous environments.

Key Topics

• Scope and Applicability
  Applies exclusively to filters with breathing hoses that are not mounted directly on masks.
  Covers particle filters, gas filters, and combined filters for unassisted respiratory devices.

• Requirements
  Defines the minimum performance characteristics for filtration efficiency, breathing resistance, and durability.
  Specifies environmental and operational conditions under which filters must perform reliably.

• Testing Procedures
  Includes laboratory tests to verify filtration performance against particles and gases.
  Details practical performance evaluations to assess real-world usability and wearer safety.

• Marking and Identification
  Establishes consistent marking guidelines to clearly identify filter type, class, and limitations.
  Ensures traceability and user information for safe application.

Applications

EN 12083:1998 filters are widely used in industries and settings where respiratory hazards are present and specialized protection is required beyond self-contained face masks. Typical applications include:

• Industrial Environments
  Protection against dust, fumes, toxic gases, and vapors encountered in manufacturing, chemical processing, and mining operations.

• Emergency Response
  Use by firefighters and hazardous material handlers where combined particle and gas filtration is essential.

• Laboratory and Pharmaceutical Work
  Filtering airborne contaminants that may be hazardous to health during experimental or production processes.

• Construction and Demolition
  Filtering dust and harmful substances generated during construction activities.

Related Standards

To ensure comprehensive respiratory protection, EN 12083:1998 is often used in conjunction with other standards, such as:

• EN 136 – Respiratory protective devices - Full face masks - Requirements, testing, marking.
• EN 143 – Particle filters - Requirements, testing, marking.
• EN 14387 – Gas filters and combined filters - Requirements, testing, marking.
• EN 149 – Filtering half masks to protect against particles - Requirements, testing, marking.

Compliance with EN 12083:1998, together with these related standards, offers a robust framework for ensuring the safety and effectiveness of respiratory protective devices incorporating hose-mounted filters.
