MASH Compared to NCHRP 350

AASHTO’s "Manual for Assessing Safety Hardware" (MASH) (2009) and NCHRP Report 350, "Recommended Procedures for the Safety Performance Evaluation of Highway Features," (1993) represent uniform guidelines used to conduct full-scale crash tests for permanent and temporary highway safety features along with recommended evaluation criteria to assess the test results. The major differences between NCHRP 350 and MASH can be summarized as follows: Test vehicles are updated to reflect the 85th percentile of the United States’ passenger vehicle fleet; Impact condition criteria are modified to correct inconsistencies and to identify needed conditions; and Evaluation criteria are modified to correct subjective criteria and to better define other criteria. Additional details showing the differences between NCHRP 350 and MASH are discussed in this paper.
