AR/MDS Approved Systems and Materials
3-5.1.1 AR, through the development of its MDS system, has established some
preferred systems and materials for the design and construction of USAR facilities.
When practical, USAR preference is that these systems and materials be used for all
USAR facilities, whether designed with MDS or not. Recommendations for departures
from these systems and materials should be reviewed with the Using Service.
