1.1   This part of EN 500 specifies the common safety requirements for mobile road construction machinery¹⁾. The EN 500 series is applicable to mobile road construction machinery as listed in Annex A. When no specific standard exists, EN 500‑1 applies.

It specifies common requirements for the design and construction of mobile road construction machinery in order to protect workers from accidents and health hazards which could occur during operation, loading, transport and maintenance.

Additional specific requirements for certain types of mobile road construction machinery are given in parts 2 to 4 and 6 of this standard.

This part of this standard gives safety requirements for all types of mobile road construction machinery and shall be used in conjunction with one of the parts 2 to 4 and 6. These machine-specific parts do not repeat the requirements from part 1 but add to or replace the requirements for the type of mobile road construction machinery in question.

Machine-specific requirements in parts 2 to 4 and 6 take precedence over the respective requirements of this standard.

For types of mobile road construction machinery not dealt with in parts 2 to 4 and 6, EN 500‑1 applies and if for those machinery additional derived risks may arise, these risks have to be taken into consideration.
