Face Mask Testing

Personal Protective Equipment (PPE)

For many companies, COVID-19 has forced business leaders to get creative—not only to keep their workers employed but also to adapt to a rapidly changing environment and produce products that are most desperately needed. Many of these companies have completely changed their production lines because of the pandemic, including shifts to make high-in-demand personal protective equipment (PPE). Since supplies have been in critical shortage as the world has geared up to fight the quickly rising number of COVID-19 cases. To help combat the coronavirus automotive manufacturers have turned their attention to building ventilators, distilleries have started making hand sanitizer, and clothing companies have started making hospital gowns. Needless to say, we are all living in a different world and no one knows when things will go back to the way they once were.

What is the purpose of testing medical face masks?

Face masks have become increasingly important to our everyday lives. Once researchers learned that COVID-19 could spread the virus before symptoms appeared and that some people have COVID-19 but don't have any symptoms and could unknowingly spread the virus to others, the use of face masks in public places became more important. Some cities and stores are requiring the use of face masks in public. Since many companies and individuals are stockpiling PPE including gloves and N95 face masks for both pharmaceutical and non pharmaceutical uses. Companies have either had to increase their production of PPE or quickly switch gears and start producing it.

What are the industry standards for testing face masks?

Surgical masks do not have the industry wide standardized test protocols because of the urgent nature of the pandemic. Masks are relatively easy to manufacture and simple to test. Many suppliers already own our test machines and are able to make small modifications to their existing systems in order to perform the required FDA testing.

Case Study

Face Mask Testing - Case Western Reserve University

In this application, our customer performed research on mask strap elasticity on units that were sterilized and used repetitively. At each sterilization cycle, three 3 cm long samples were cut from elastic straps of 2 masks. The test samples were gripped in a TestResources testing machine and loaded for 2 consecutive loading and unloading cycles under tension at a rate of 1 mm/s. The testing profile included 2 consecutive cycles of load relaxation such that the sample was stretched 3 times the original length, was held at constant deformation for 5 minutes, and was unloaded. Load values at peak deformation and load-relaxation values for each cycle were recorded. As such, relaxation represented the capacity of straps to retain a load over time. The elasticity of samples was from the slope of the line connecting the zero load with the peak load in the load deformation plot.
