Australia mountain bike governing body MTBA recently announced that from July 1 2006, full-face helmets will be mandatory at all MTBA sanctioned DH events. This week, the organisation further clarified the rule by releasing a list of compliance standards. In short, the organization states that competition helmets must carry the Australian Standards compliance sticker or an international equivalent. The first list of standards that MTBA will accept as an international equivalent to the Australian/New Zealand Standard 2063 is as follows:
(1) ANSI Z90.4;
(2) Snell "B" or "N" series;
(3) ASTM F-1447.
(4) Canadian CAN/CSA-D113.2-M;
(5) U.S. CPSC standard for bicycle helmets;
(6) European CEN standard for bicycle helmets (EN1078)
Other international standards may be added from time to time.
