Dana Cork Sticky Note Can we add the crash test data for this railing. The standard it meets (AASHTO MASH, NCHRP, etc.) and the test level. If it meets MASH is that 2009 or 2016.? If it meets NCHRP which report? Basically, I want to look at this drawing and be able to determine how to code SNBI item B.RH.02 for the transition railing.
