  • What is AS/NZS 3845.1:2015

    The Australian standard relating to road barrier systems. Under AS/NZS 3845.1:2015, MASH has been nominated as the crash testing standard for safety barrier systems.

  • What does Mash mean?

    Mash (Manual for Assessing Safety Hardware) is an international standard that has been adopted in Australia for crash testing of safety devices. The 2009 Mash replaces the previous testing standard: the NCHRP-350.  All new crash barriers installed on NSW public roads must pass the MASH criteria in order to be allowed for use.

  • What does NCHRP-350 mean?

    NCHRP-350 (National Cooperative Highway Research Program Report 350) is an international standard that was previously adopted in Australia for crash testing of safety devices. This has now been superseded by the MASH standard. NCHRP-350 accepted hardware is still approved for new installation and replacement. All new product innovations must be tested under the updated MASH standard.

  • What is a clear zone?

    The horizontal width of space available for the safe use of an errant vehicle which consists of the verge area and is measured from the nearside edge of the left-hand traffic lane. In the case of a divided road, it is also measured from the offside edge of the right-hand traffic lane to the edge of pavement for opposing traffic.

  • What is the working width?

    The maximum width that is required to prevent an impacting vehicle from colliding with an object behind a road safety barrier system. This includes both the dynamic deflection and the extra width due to the roll of the impacting vehicle.

  • What is a terminal?

    The specially designed end pieces of a road safety barrier system. The leading terminal is on the end of the road safety barrier system that faces oncoming traffic and the trailing terminal is on the other end. Terminals are subdivided into classifications of gating and non-gating terminals.

  • What is a gating terminal?

    Terminals that are designed to break away, pivot or hinge, and that allow a vehicle to pass through when impacted at an angle to the end, or at a point upstream of the beginning length of the associated road safety barrier system

  • What is a non-gating terminal?

    Terminals that are designed to redirect a vehicle and absorb part of the energy of an impacting vehicle at any point along the terminal without allowing it to pass behind the road safety barrier system.

  • What is the point of need?

    The point that a terminal will redirect an errant vehicle rather than allowing it to pass through. This is measured from the beginning of the terminal.
