NOTE 2 The requirements specified in this document are common to two or more families of mobile road construction machinery.

This document gives safety requirements for all types of mobile road construction machinery and shall be used in conjunction with one of parts 2 to 7. These machine specific parts do not repeat the requirements from part 1 but add to or replace (supplement or modify) the requirements for the type of mobile road construction machinery in question.

This document does not deal with hazards related to transport of dangerous goods by road.

This document specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards as specified in Annex H.
