Mask Fit Test
The face mask is a protection element that is used to prevent infection and to protect the mouth and nose area against any splashes that may occur during a medical operation, its structure can be changed to cloth, fabric or leather and is worn on the face. It can also be used to prevent airborne infectious microbes from entering the body through the mouth. Due to the recent epidemic, it is obligatory to wear masks in public and crowded environments, public transportation vehicles or markets and shopping centers. As a result, we can say that face masks also function as a physical barrier for protection from viral and bacterial particles. As the masks enter our lives so much, mask suitability tests have also gained importance. Mask fit tests can be applied according to many variables. Mask compatibility tests play a major role in ensuring the requirements for the appropriate design of the performance values ??of these masks in which environment and under which conditions they will be used. The tests are done in accredited mask testing laboratories. Face masks are named differently as a result of the mask compatibility test performed according to many variables.
One of them is the surgical mask.
What is a Surgical Mask?
Surgical face masks, which are produced for medical purposes, are also known as medical masks. Medical masks are masks designed for use in medical environments such as operating rooms and environments where different activities with similar requirements are performed. There are mask conformity test standards applied to these masks and test criteria required in line with these standards.
Surgical Mask Test
The mask compatibility test applied in such masks is applied on the finished product or a piece taken from the final product. As a result, the mask compatibility test made on the raw material of the mask shows its adequacy in terms of usability.
The efficiency of the medical face mask depends on factors such as filtration efficiency, material quality and whether it sits on the face of the person using it. In addition to the necessity of paying attention to the filters to be used in their construction, they should not be disintegrated, split or torn during use. Mask compatibility tests of surgical masks should be carried out in mask test laboratories where certain conditions are met. The most important standard to pay attention to is the EN 14683 standard. This standard defines two different types of surgical masks. The medical face mask, called Type I, is used in patients to reduce the risk of infection, especially in epidemic and pandemic situations. Masks called Type II are used by healthcare professionals working in operating rooms or environments where healthcare practices are performed. Mask conformity tests applied to surgical masks:
• Bacterial Filtration Efficiency (BFE) test
• Differential, Wind Pressure (Breathability) test
• Microbial Cleanliness test
It can be sorted as
Apart from these masks, there is also a requirement such as biocompatibility in the mask fit test.
• Sensitization test
• Irritation test
It can be sorted as
In the period we live in, the demand for masks has increased with the epidemic. It is seen that surgical masks and respiratory protective masks, where the mask conformity test is applied, are used in every field.
What is a Respiratory Protective Mask?
It is the type of equipment that is preferred as personal protection, worn in environments where the oxygen rate is insufficient or there are unwanted microparticles in the air. Respiratory mask types are widely preferred against epidemic diseases and air pollution that we encounter in daily life, as well as used in many different sectors and workplaces. The masks, which fit tightly to the face and are designed to form a seal in this way, are designed to filter the air inlet and outlet. The requirements to be complied with while designing vary according to the environment to be used. Different masks are subjected to conformity tests and this mask is used as a result of conformity tests.
Finally, the most critical point and steps performed during the conformity assessment of the masks are the mask conformity tests. Determining which performance meets its values ??and the adequacy of the masks to be used will give appropriate and appropriate results in terms of usability. It is absolutely essential to apply the mask fit test to ensure that the basic needs of the mask are met. The mask conformity test applied in mask test laboratories is sensitive to multiple errors that may occur at the same time and is carried out within the controls. Mask suitability tests give precise results in accordance with the needs and requirements of face masks designed for all uses.
