Part 2:
Specific requirements for road-milling machines
1 Scope
This part of ISO 20500, together with part 1, deals with all significant hazards for road-milling machines
when they are used as intended and under the conditions of misuse which are reasonably foreseeable by
the manufacturer associated with the whole life time of the machine (see Annex D).
The requirements of this part are complementary to the common requirements formulated in
ISO 20500-1.
This document does not repeat the requirements from ISO 20500-1, but adds or replaces the
requirements for application for road-milling machines.
The following significant and relevant hazards are not covered in this document:
— Lightning.

4.2.2 Visibility performance criteria
The machine meets the requirements of this International Standard if the measurement results show no
maskings or maskings smaller than or equal to the performance criteria with direct or indirect view as
specified in Table 1.
When there are two operator positions on the operator’s station the resulting maskings may be a
combination (overlapping) of the individual maskings.

design of the machine.
Annex C describes the test procedure for evaluating the capture efficiency of such an EVAC-ERD.
