ISO 20474-8:2008 specifies safety requirements and protective measures specific to graders, including operator positions, fenders, steering systems, steering controls, and traveling-mode safety. It is intended to be used with ISO 20474-1 for general earth-moving machinery safety requirements and ISO/TS 20474-14 for mandatory national and regional provisions. The standard addresses significant hazards during commissioning, operation, and maintenance, and includes verification requirements, operator information provisions, and illustrative grader configurations.
Application Scope: This standard applies to graders as defined in ISO 6165 and supports manufacturers, designers, safety engineers, regulators, and organizations responsible for the safe operation and maintenance of earth-moving machinery.
