AS 12508:2021 – Earth-moving machinery -Operator station and maintenance areas- Bluntness of edges (ISO 12508:1994, MOD).
AS 12508 defines the permissible limits of the sharpness of edges and corners, to reduce the risk of injury to the operator or maintenance personnel while operating earth-moving machinery and performing maintenance. It applies to operator and maintenance access/egress systems as defined in ISO 2860 and ISO 2867, and the operator station on earth-moving machinery as described In ISO 6165.
