From the ANDRA site..... CLARIFICATIONS OF CURRENT AUSTRALIA STANDARDS WITH REFERENCE TO HELMETS ANDRA has been contacted by a number of competitors concerning a perceived lack of availability of helmets meeting the current Australian / New Zealand Standard. It also appears that many helmets currently on the market have the older AS1698 standard decal, indicating that the helmet may not meet the required AS/NZS 1698:2006 – AS/NZS 1698 standard. The AS/NZS 1698:2006, which is also labelled as AS/NZS 1698, supersedes both the older AS 1698:1988 and AS 1698:1974. After further communications with Standards Australia, confirmation has been again obtained clearly stating that the actual accepted standard and labelling is the newer standard; AS/NZS 1698:2006 – AS/NZS 1698. Older standards are no longer recognised by Standards Australia for motor sport activities and therefore are not acceptable. ANDRA again wishes to inform all Tracks, Track Officials, ANDRA Officials, National Control Council Members and Division Delegates that it was Standards Australia that took this course of action which ANDRA needed to implement as a matter of safety. The following was sent directly to ANDRA from Standards Australia / SAI Global as part of a recently written reply on this subject: “Since the Standard was revisited in 2006 our label has changed slightly. We never put the year on our standards mark labels, the way you can differentiate the new label in that it now shows AS/NZS 1698, the previous label was only AS 1698.” The decal / sticker that appear on all helmets meeting the new Australian Standard is: Other helmet standards accepted by ANDRA, directly related to relevant performance levels found in section 4.10.8 Helmets of the 2008/2009 ANDRA Rulebook, are SNELL SA2000, SNELL SA2005 , SNELL M2000, SNELL M2005, SFI 31.2A, SFI 41.2A (or later) and BS 6658-1985. On November 5 2008 the NHRA issued a media release titled “NHRA Technical Services previews rules changes for 2009 season”. Through this release there were several references to the K98 helmet standard no longer being permitted. Currently ANDRA does not permit, nor accept the K98, as an accepted helmet standard for use in ANDRA Championship Drag Racing. Hope this helps....
