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.
Diana Wyman is Executive Vice President of AATCC, a professional association and standards development organization for the global textile industry. Diana has been involved in all aspects of textile testing—from managing a contract lab to developing specifications for a retail brand. She has participated in the standards development process as both staff and volunteer for AATCC as well as textile-related committees of ASTM, IEC, IPC, and ISO. Diana holds degrees in Fashion Merchandising, Textiles, and Business Administration.

Hydrostatic Pressure Testing for Textiles Webinar
Recorded June 3, 2020
Presented by Erika Simmons, AATCC Technical Director
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.
The third webinar in this series:
Overview of Surgical Mask and Respirator Requirements
Recorded July 9, 2020
Presented by Matthew T. McGarrity, SGS – North America, Inc.
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.

Low-cost Measurement of Facemask Efficacy for Filtering Expelled Droplets During Speech
Recorded September 24, 2020
Presented by Dr. David Grass, Research Associate, Warren Group, Dept of Chemistry, Duke University
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.
