MEDICAL SURGERY FACIAL MASKS
TECHNICAL REQUIREMENTS AND TESTS
Medical surgical masks are divided into two main groups, Type I and Type II, according to their bacteria filtration efficiency. It is divided into Type II or Type IIR according to its splash resistance. There are separate requirements for each type.
The European standard EN 14683 covers test methods and manufacturing and performance features for surgical masks designed to limit the transmission of infectious agents from personnel to patients (and vice versa) during surgical procedures in operating rooms and other medical settings with similar characteristics.
Surgical masks are divided into three classes. Type I, TypeII and Type IIR.
Suitable for Type I patients, Type II and Type IIR healthcare professionals.
According to the relevant EN 14683 standard, the following tests are performed according to the selected mask type.
- Bacteria Filtration
- Differential Pressure
- Synthetic Blood Penetration Test (Only for TYPE II R)
- Microbiological Cleaning (Bioburden)
EN 14683 Performance tests; In vitro evaluation of bacteria filtration efficiency (BDE), air permeability (differential pressure), microbial cleaning, splash resistance according to ISO 22609: 2004 standard (for Type IIR masks) and biocompatibility tests. All performance tests should be as in table 1.
What Is The Meaning Of FFP Used In Dust Masks?
It means filter piece for inhalation + Disposable + Maintenance-free dust mask.
Why are they classified as FFP1 - FFP2 - FFP3? What are the differences of these classes?
This classification and ranking classified the filtration performance as defined in EN 149: 2001 + A1: 2009 standards according to the European Union Personal Protective Equipment Directive.
