In light of COVID-19 (coronavirus) and our priority for the health and welfare of our members and staff, ASTM International has decided that it is inadvisable and impractical to hold the committee meetings in Prague on April 27-May 1. The decision was based on several factors, including, but not limited to:

    • Continued review of information and recommendations from the U.S. Centers for Disease Control and Prevention (CDC), the World Health Organization (WHO) and other governmental bodies.
    • Input from our members whose organizations are increasingly concerned with travel and the large gathering in Prague.
    • Watching the expanding trajectory of the coronavirus.

    Staff managers will be contacting committee leaders to plan alternatives for conducting committee business. For any committees that collected money for events, ASTM will work to issue refunds as necessary. Attendees are responsible for cancelling their own hotel reservations.

    Looking forward, we will rely on these and other relevant criteria and input points to assess the status of future scheduled ASTM meetings and events. Please consult our meeting webpage for the most up-to-date information. Thank you for your understanding and continued commitment to ASTM International.
