ASTM International staff will confer with C01 Committee on Cement and C09 Committee on Concrete and Concrete Aggregates leadership regarding alternatives to meetings scheduled June 28-July 2 in Boston, all of which have been canceled. ASTM announced the change in response to continued review of information and recommendations from the U.S. Centers for Disease Control and Prevention, the World Health Organization, and other governmental bodies; input from ASTM International members whose organizations are increasingly concerned with travel; and, specific information on the projected city restrictions, with input from the hotels. Looking forward, ASTM will rely on these and other relevant criteria and input points to assess the status of future standards development meetings.
