Hydrostatic pressure testing is required for level 2 and 3 medical gowns and drapes. It is also commonly used for evaluating high-performance rainwear. Learn to properly perform and interpret this test for any application, including when and how to use a restraint. The webinar addresses all aspects of AATCC TM127 and TM208.

Impact penetration testing measures the amount of liquid that passes through a fabric under specified conditions. It is a key test for Level 1, 2, and 3 gowns and drapes in healthcare settings. This webinar will cover testing for PPE as well as other water-resistant applications. It will compare various versions of the test, including AATCC TM42, NWSP 80.3, and ISO 18695. The webinar includes full descriptions and demonstration of apparatus, materials, and testing procedure.
This presentation will provide an overview of surgical masks and respirator industry standard, methods, and regulations. Also discussed will be the U.S. Food and Drug Administration’s actions to help alleviate the shortage medical PPE through COVID-19 Emergency Use Authorizations (EUA’s) and Enforcement Policies. The interim policies specifically relating to surgical masks and respirators will be highlighted.
Mandates for mask use in public during the recent COVID-19 pandemic, worsened by global shortage of commercial supplies, have led to widespread use of homemade masks and mask alternatives. It is assumed that wearing such masks reduces the likelihood for an infected person to spread the disease, but many of these mask designs have not been tested in practice. We have demonstrated a simple optical measurement method to evaluate the efficacy of masks to reduce the transmission of respiratory droplets during regular speech. In proof-of-principle studies, we compared a variety of commonly available mask types and observed that some mask types approach the performance of standard surgical masks, while some mask alternatives, such as neck fleece or bandanas, offer very little protection. Our measurement setup is inexpensive and can be built and operated by non-experts, allowing for rapid evaluation of mask performance during speech, sneezing, or coughing.
PPE comes in many forms: gloves, masks, face shields, goggles, gowns, etc. The COVID-19 pandemic has caused worldwide shortages in PPE and forced a reimagining of PPE. From disinfecting and reuse to incorporation of antimicrobial agents, PPE is changing. How effective will these changes be? We will have to lean heavily on current standard test methods, as well as developing new ones.
During this presentation, we will discuss what we mean by “antimicrobial”. We will also go over current standard test methods for antimicrobial products and their positives and negatives. Finally, we will end by discussing where the antimicrobial testing field needs to go in order to meet the needs of this ever-evolving industry.
