Reaffirmed 2023

1. SCOPE

1.1 This standard (Part 5) gives the safety requirements specific to hydraulic excavators as defined in IS/ISO 6165. It is intended to be used in conjunction with IS 17055 (Part 1), which specifies general safetyrequirements common to two or more earth-moving machine families. The specific requirements given in this document take precedence over the general requirements of IS 17055 (Part 1).

This standard deals with all significant hazards, hazardous situations and events relevant to the earthmoving machinery within its scope (see IS 17055 (Part 1) : 2018, Annex A) when used as intended or under conditions of misuse reasonably foreseeable by the manufacturer. It specifies the appropriate technical measures for eliminating or reducing risks arising from relevant hazards, hazardous situations or events during commissioning, operation and maintenance.

1.2 This standard is not applicable to machines manufactured before the date of its publication.
