ASTM F2100
The standard that covers the performance requirements and test methods for materials used to construct medical facemasks used in providing healthcare such as surgical services and patient care. However, this specification does not evaluate all aspects of medical facemask design such as barrier properties, breathability, and respiratory protection regulations.

• ASTM Level 2: Ideal for procedures in which there is moderate risk of fluid exposure (splashes or sprays can be produced).
• ASTM Level 3: Ideal for procedures in which there is high risk of fluid exposure (splashes or sprays will be produced).
