What is ASTM?

ASTM International is a global organization that develops and publishes technical standards for an expansive array of products, materials,

systems and services. Today, more than 12,800 ASTM standards are in use around the world, including ASTM F2100-11, the standard

for medical face masks since 2012.

Tell me more about how masks are tested

The five performance metrics and their related tests are:

This test measures the percentage of bacteria larger than 3 microns filtered out by the mask. The challenge material used is

Staphylococcus aureus.

This test measures the percentage of particles larger than 0.1µm (0.1 micron) filtered out by the mask. The challenge material used

consists of latex aerosol concentrations in a controlled airflow chamber.

• Fluid Resistance - Test ASTM F1862

This test evaluates the resistance of a medical face mask to penetration by a small volume (~2 mL) of synthetic blood at a high velocity (80

mmHg, 120 mmHg, or 160 mmHg). The mask either passes or fails based on visual evidence of synthetic blood penetration.

• Breathability - Test ASTM F2100 C: ?P

This test determines the face mask’s resistance to airflow. A controlled flow of air is driven through the face mask and the pressure before

and after is measured. The difference in pressure is divided by the surface (in cm²) of the sample. A lower breathing resistance

indicates a better comfort level for the user.

• Flammability - Test 16 CFR Part 1610: Flame Spread

This test exposes the face mask material to a flame and measures the time required for the flame to proceed up the material a distance of

127 mm (5 inches). Class 1 means the material exhibits normal flammability and is acceptable for use in clothing.

ASTM F2100-11: Standard Specification for Performance of Materials Used in Medical Face Masks and

the performance of BioMask 3-Layer Protective Mask (Lot. No. BM202007CY1)

In 2020, Cyber started their disposable face mask division to cater to the need of the local and regional community during the COVID-19

pandemic. We adhered to the call to make Singapore more self-sufficient and therefore decided to set up a manufacturing facility in

Singapore to manufacture disposable protective face mask. Our objective is to produce affordable and good quality disposable face

mask. We will be sending each batch of face mask for lab test by an international body to give you greater peace of mind.
