Australia was a founding member of the UNECE in 1958. The full specification is available from UNECE
The specification should be used for technical details, rider compliance information is below
The helmet labelling requirement is :-
An international approval mark of a circle around the number "E" followed by the number of the country which has granted the approval followed by the approval number, a dash and a symbol as set out below
"J" if the helmet does not have a lower face cover
"P" if the helmet has a protective lower face cover, or
"NP" if the helmet has a non protective lower face cover
The symbol is followed by a dash and the production serial number
On helmets the marking is required to be sewn onto the retention system (chin strap).
The visor labelling requirement is :-
The international approval mark of a circle around the number "E" followed by the number of the country which has granted the approval, a reference alphanumeric number and on a tinted visor the day time use only symbol (RHS pic)
The labelling must be indelible, clearly legible and not in the main visibility area.
Clear Visors - visible light transmittance of between 80 and 100%
Tinted Visors - visible light transmittance of between 50 and 80%
The UNECE 22.05 specification stipulates initial testing and ongoing quality control of helmets and visors
Initial Batch Testing from a maximum batch size of 3200 is 40 to 50 Helmets and 20 to 30 Visors
Ongoing Quality Control is a batch sample rate of 1 in 125 helmets which moves to a strengthened batch rate of 1 in 66 if out of 22 consecutive tests 2 failures are detected.
The normal sample rate for visors is a batch sample rate of between 1 in 166 and 1 in 640 dependent on batch size, where the first samples fail a second sample is taken. If 2 out of 5 consecutive samples fail it moves to a strengthened batch rate of between 1 in 150 and 1 in 246 dependent on batch size with the same second sample provisions where a failure in the first sample occurs.
Note - In the EU and UK goggles are handled under a separate standard EN1938 and allow VLT 18% to 80%.
