BS EN 149 is a European standard on respiratory protective devices that discuss the requirements and test methods for filtering half masks to ensure protection against particles. BS EN 149 specifies minimum requirements for filtering half masks as respiratory protective devices to protect against particles except for escape purposes.
Laboratory and practical performance tests are included for the assessment of compliance with the requirements.
BS EN 149 on the requirements and test methods for filtering half mask is useful for:
A particle filtering half mask covers the nose, mouth, and chin and may have inhalation and/or exhalation valve(s). The half-mask consists entirely of filter material or comprises a facepiece in which the main filter(s) form an inseparable part of the device. It is intended to provide adequate sealing on the face of the wearer against the ambient atmosphere when the skin is dry or moist and when the head is moved.
BS EN 149 provides you with guidance on requirements for visual inspection, packaging, cleaning, and disinfecting, practical performance, the finish of parts, breathing resistance, testing of the strength of attachment of exhalation valve housing, and carbon dioxide content of the inhalation air, flammability, marking, etc.
The requirements and test methods provided by BS EN 149 assist you in improving the performance and quality of the filtering half masks, satisfy user's expectations and provide the best of its utility and benefits ensuring protection against the inhalation of particulate contaminants.
With obedience and compliance to BS EN 149, you can enhance filtering half masks’ effectiveness and efficacy and manufacture a standardized high-quality product.
