N95 / EN 149 Face Mask Testing Lab

How is Facemask testing done in a Lab?

In the United States, respirator production is regulated by NIOSH. These devices take the place of N95 disposable respirators and are typically reserved for medical and professional personnel.

In Europe, respirators must be of the same mind following EN 149, which outlines the requirements for three types of particle-filtering respirators: FFP1, FFP2 and FFP3, with China and India also having respirator standards and study requirements in place.

Difference Between a Respirator and Face mask

A respirator is a tight-fitting filtering slope-fragment.

The wearer’s nose and mouth will be at least covered by the edges of the respirator in a tight seal.

This gives pleasing breathability to use as the tendency part doesn’t fall out after the entryway to the mouth.

It is intended to obtain the entire near-facial fit and not examine the efficient filtration of airborne particles, dust particles, and infectious agents.

Particulate respirator is most commonly used for COVID-19 prevention as it intends to filter out airborne particles.

Similar to medical masks, respirators that are meant to prevent transmission of disease or topic to strict regulatory standards in oscillate countries by now best made commercially understandable.

ITC India is capable of testing N95 Respirator Masks for safety in accordance with the following standards:

  • ANSI Z 87.1,
  • ASTM 1862,
  • CPSC-CS-191-53
  • MIL-STD 36954C
  • 29 CFR 1910.134
  • IS 9473/EN 149
  • NIOSH TEB-APR-STP-004 etc.

Mask Varieties

There are numerous alternatives to wearing a mask at some point during the corona-virus pandemic, including in the medical field.

 These are the numerous kinds of masks and respirators, as described by the Centres for Disease Control and Prevention for Medical Systems.

Cloth: Cloth masks may be crafted from loads of fabric. Lots of other kinds of material masks are available.

Cloth Masks

Surgical or Procedure Masks: Disposable technique masks are broadly possible. They are, every now and then, known as surgical masks or clinical technique masks.

Surgical or procedure Masks

KN95 Respirators (and identical alternatives): A few respirators are supposed to be examined to fulfil global requirements. The most commonly acquired mask assemblies globally are the KN95 respirators.

The N95 respirator is one of the most distinguished respirators assigned by the NIOSH.

Other identical alternatives: N99, N100, P95, P99, P100, R95, R99, and R100.

 Other Masks:

A few masks are supposed to be examined to make sure they produce an impact at a constant level. There are numerous requirements which have been issued via the National Institute for Occupational Safety and Health and the masks are categorised primarily based on the acquisition they meet.

The Respiratory Certification Test

The respiratory system is intended for submission to NIOSH, NaCl, DOP, and Valve Leak, to ensure that the respiratory system meets the minimum performance requirements.

And it may also require an inhalation/breath test.

These tests can be performed by the manufacturer or a third-party laboratory and must follow the NIOSH Standardized Test Procedure (STP) and use the appropriate equipment.

 The Sodium Chloride (NaCl) Aerosol Challenge uses a widely accepted method for assessing the particle penetration and airflow resistance properties of various filter materials. Other materials such as B. Respiratory system filters, face masks, etc. are tested to determine filtration efficiency for marketing purposes.

 The Dioctyl phthalate (DOP) test is used to evaluate the particle penetration and aeration resistance properties of various filter materials, including HEPA filters and NIOSH. Respiratory and filter media tests are performed according to 42 CFR Part 84 and NIOSH procedure numbers RC-APR-STP-0057, 0058, and 0059 prior to submitting for NIOSH certification for respiratory organs.
