Dicke WZ-Letters

MASH Eligibility Letters

Dicke stands that have been crash tested to MASH have this label.

AASHTO’s Manual for Assessing Safety Hardware (MASH) was released in the Spring of 2016 and is considered an updated replacement of NCHRP 350. AASHTO defines MASH as providing “uniform guidelines for crash testing permanent and temporary highway safety features and recommends evaluation criteria to assess test results.”
The table below provides WZ numbers with links to the letters on the FHWA website.
