Overview

EN 142:2002 is a CEN European Standard that defines minimum requirements, testing and marking for mouthpiece assemblies used in respiratory protective devices (RPD), excluding escape apparatus and diving apparatus. It sets design, materials and performance criteria and specifies both laboratory and practical performance tests to assess compliance. The standard supports conformity assessment for manufacturers, test laboratories and procurement bodies across Europe.

Key Topics and Technical Requirements

• Scope and designation
  • Applies to mouthpiece assemblies as components of RPD; designated as “Mouthpiece assembly EN 142.”
  • Excludes escape and breathing apparatus for diving.
• Ergonomics and design
  • Interaction between wearer, mouthpiece assembly and working environment is considered.
  • No protruding parts, sharp edges or features likely to restrict airflow or become entangled.
  • Mouthpiece must minimize inward leakage between lips and mouthpiece.
• Materials
  • Sufficient mechanical strength; materials contacting skin must not cause irritation.
  • Exposed parts must not be aluminium, magnesium, titanium or spark-producing alloys.
• Cleaning and disinfecting
  • Materials and construction must withstand manufacturer-recommended cleaning and disinfection procedures.
• Temperature and flammability
  • Must resist specified conditioning; threaded connectors to EN 148 series must remain within gauge.
  • Parts exposed to flame shall not continue to burn for more than 5 s after flame removal.
• Demountable and replaceable parts
  • Replaceable items (head harness, valves, connectors) and demountable connections must be serviceable and retain seals during maintenance.
• Head harness and mechanical strength
  • Harness adjustable/self‑adjusting and secure; straps, buckles and lugs must withstand a 50 N pull for 10 s without failure or slipping.
  • Connection between mouthpiece body and connector must resist an axial tensile force of 50 N.
• Valves, leakage and breathing resistance
  • Requirements and test methods for inhalation/exhalation valves, leaktightness and breathing resistance are specified, including practical performance tests (walking and work simulation).

Applications and Users

Who uses EN 142:2002:

• Manufacturers of mouthpiece assemblies and RPD components - for design, CE marking and technical documentation.
• Test laboratories - to perform laboratory and practical performance tests specified by the standard.
• Procurement and safety managers - to specify compliant components for workplace respiratory protection.
• Regulators and conformity assessors - for compliance with EU directives and national implementation.

Practical applications:

• Selection and verification of mouthpiece assemblies for industrial rescue, firefighting support, and occupational respiratory systems (non-diving).
• Design validation during product development and after material/process changes.
• Maintenance and replacement policies informed by replaceability and cleaning requirements.
