This standard establishes for the first time a set of test methods that evaluate the filter, fit and leakage performance of barrier face coverings, commonly referred to as “facemasks” worn by the general public, and not to be confused with respirators nor medical or surgical masks.  The webinar will be presented by respiratory expert, Jeff Stull, Vice Chair of the ASTM Committee that wrote the standard, and Dave Rousse, INDA President.  It will provide a detailed review of the new ASTM standard and the test methods it entails and the impact on the entire supply chain of facemask production.

The purpose of guidance for the general public to wear facemasks is to control the spread of viruses. Facemasks made to this new ASTM standard will also provide a degree of particulate filtration to reduce the amount of inhaled particulate matter.

The goal of the standard is to assist consumers in making informed decisions about facemasks given the vast array of products currently for sale, including various patterns promoted for home-made manufacture using common textile materials.  Prior to the ASTM standard, no standard test method existed which allowed comparisons among different products nor were there any minimum performance requirements.  This new standard provides these performance requirements as well as a set of specifications, guidelines and expectations for facemask manufacturers and media suppliers.

“We approached NIOSH last year on developing a general public facemask standard that could use nonwoven materials beyond Meltblown that still deliver an effective level of filtration, as there was so much demand for the N95 respirators and masks once the Asian supply chain was cut off,” said Dave Rousse, INDA President.  “We were delighted to get a positive response from Jon Szalajda, NIOSH Deputy Director, National Personal Protective Technology Laboratory, who is also the Chair of the ASTM Committee dealing with standards in this area.”
