What is EN 149:2001+A1:2009 – Respiratory protective devices – Filtering half masks to protect against particles – Requirements, testing, marking?
EN 149 is a European standard that specifies the requirements, testing methods, and marking for filtering half masks used as respiratory protective devices to protect against particles. Here’s an overview of EN 149:
Scope: EN 149 applies to filtering half masks that cover the nose, mouth, and chin and are designed to protect against particles in the air. It includes both valved and non-valved half masks. The standard does not cover masks for use in environments with hazardous gases or vapors.
Classification of filtering half masks: EN 149 classifies filtering half masks into three categories based on their filtering efficiency:
- FFP1 (Filtering Face Piece 1): These masks provide the lowest level of protection, with a minimum filtration efficiency of 80% against particles.
- FFP2 (Filtering Face Piece 2): FFP2 masks offer a higher level of protection, with a minimum filtration efficiency of 94% against particles.
- FFP3 (Filtering Face Piece 3): FFP3 masks provide the highest level of protection, with a minimum filtration efficiency of 99% against particles
Requirements for filtering half masks: EN 149 sets out various requirements that filtering half masks must meet, including:
Particle filtration efficiency: Masks must achieve the minimum filtration efficiency specified for their category (FFP1, FFP2, or FFP3)
Breathing resistance: Masks should have low breathing resistance to ensure comfort during use.
Leakage: Masks must have a proper seal to minimize inward leakage of particles
Inhalation and exhalation valves (for valved masks): If present, valves must meet specific requirements to maintain the intended level of protection
Testing methods: The standard outlines testing methods to evaluate the performance of filtering half masks. These include tests for filtration efficiency, breathing resistance, practical performance (e.g., fitting and field of vision), and compatibility with other personal protective equipment.
Marking and identification: EN 149 specifies the required marking and identification information that should be present on the filtering half masks. This includes the manufacturer’s name or trademark, the mask’s classification (FFP1, FFP2, FFP3), the conformity marking, and any additional information as required by the standard
Furthermore, EN 149 is an important standard that ensures the quality and performance of filtering half masks used for respiratory protection against particles. Compliance with this standard provides confidence to users that the masks meet specific requirements and offer the intended level of protection.
Requirements of EN 149 – Respiratory protective devices
Filtering efficiency: EN 149 sets minimum requirements for the filtration efficiency of filtering half masks. The masks are classified into three categories: FFP1, FFP2, and FFP3, with increasing levels of filtration efficiency.
The minimum filtration efficiencies for these categories are as follows:
FFP1: ≥ 80%
FFP2: ≥ 94%
FFP3: ≥ 99%
Breathing resistance: The standard specifies limits for the breathing resistance of filtering half masks. Masks should provide low resistance to breathing to ensure comfort during use
Inward leakage: EN 149 mandates that filtering half masks should have a proper seal to minimize inward leakage of particles. This ensures that the masks provide effective protection.
Inhalation and exhalation valves (for valved masks): If the filtering half mask includes inhalation and/or exhalation valves, the standard sets requirements for their performance. These valves should not affect the intended level of protection provided by the mask.
Compatibility with other personal protective equipment (PPE): If the filtering half mask is intended to be used in conjunction with other PPE, EN 149 specifies requirements for ensuring compatibility and proper integration with other protective equipment.
Testing methods: The standard outlines testing methods to assess the compliance of filtering half masks with the specified requirements. These tests include evaluating filtration efficiency, breathing resistance, practical performance (e.g., fitting and field of vision), and compatibility with other PPE.
Marking and identification: EN 149 provides guidelines for the required marking and identification information to be present on the filtering half masks. The markings include the manufacturer’s name or trademark, the classification of the mask (FFP1, FFP2, FFP3), the conformity marking (CE mark), and any additional information as required by the standard.
Therefore, compliance with EN 149 ensures that filtering half masks meet specific quality and performance requirements, offering reliable respiratory protection against particles. It enables users to identify suitable masks based on their filtration efficiency and provides assurance of the masks’ conformity with the standard.
