I have recently been given a short (1 week) trial access to standards australia online database. given the expense of these documents, and knowing that there many standards which affect motorcyclists, I thought I would go through and try and retrieve as many relevant standards as possible. E.g. I have already retreived as 1698. Are there any others that people can think of that may be relevant or useful to have? (anyone recall the number or proper title for exhaust noice standards?) Interestingly - there is handbook available: HB 173-2000 Motorcycle protective clothing - Guidelines for manufacturing . But since it is not officially a standard I can't download it.
