What is BS EN45538-2:2017?

BS EN45538-2:2017 is a technical standard that stands for "Requirements and test methods for medical face masks - Part 2: Test methods". It sets out the requirements and test procedures for evaluating various aspects of medical face masks, ensuring their safety, and performance in protecting users against biological agents.

Methods for Testing Medical Face Masks

One of the key aspects covered in BS EN45538-2:2017 is the testing of medical face masks to determine their effectiveness in filtering particles and microorganisms. This involves conducting tests to assess the mask's bacterial filtration efficiency (BFE), particulate filtration efficiency (PFE), breathability, splash resistance, and more.

For the BFE test, the mask is challenged with aerosolized bacteria and the percentage of bacteria that are filtered out by the mask is determined. The PFE test evaluates the mask's ability to filter particles of specified sizes. Both tests help assess the mask's ability to protect the wearer and prevent the spread of infectious agents.

Compliance and Certification

Manufacturers of medical face masks must comply with BS EN45538-2:2017 to ensure that their products meet the necessary safety and performance standards. Compliance involves rigorous testing of the masks according to the specified methods and criteria outlined in the standard.

Once a mask meets the requirements, it can be certified as compliant with BS EN45538-2:2017. Certification plays a crucial role in assuring users, such as healthcare professionals and the general public, that the mask has undergone thorough testing and provides reliable protection.

Importance of BS EN45538-2:2017

The importance of BS EN45538-2:2017 cannot be overstated, especially in the context of public health crises and infectious disease outbreaks. Properly tested and certified medical face masks provide a crucial barrier against the transmission of infectious agents and help protect both the wearer and those around them.

Without a standardized testing procedure like BS EN45538-2:2017, it would be challenging to ensure the reliability and effectiveness of medical face masks on the market. The standard helps establish minimum performance requirements and enhances confidence in the quality of masks used in various healthcare settings and other environments where protection is essential.
