SNZ AS/NZS 3845.2
Road safety barrier systems and devices Part 2: Road safety devices
|Publication Date:||27 February 2017|
This Part of the Standard sets out the requirements for both permanent and temporary road safety devices including-
(b) longitudinal channelizing devices;
(c) truck or trailer mounted attenuators;
(d) rear underrun protection devices; and
(e) sign support structures and poles.
NOTE: Longitudinal road safety barriers, terminals, crash cushions, interfaces (including transitions) and longitudinal barrier gate systems are specified in AS/NZS 3845.1.
The intention of this Standard is to ensure that road safety devices are crashworthy when impacted by a vehicle under specified conditions.
This Standard includes the following:
(i) Testing methods and data.
(ii) Considerations in the evaluation process.
(iii) Manufacturing requirements.
(iv) Issues to be addressed in specifying road safety devices including documentation required.
(v) Erection and maintenance practices necessary to achieve expected performance.
(vi) Minimum site conditions (cross slope, placement of kerbs or similar) that enable the device to have acceptable performance when impacted.
(vii) Steps to evaluate the nature of repairs necessary following a crash.
This Standard makes significant reference to MASH and NCHRP 350. It also references some relevant European CEN Standards.
