Scope

This document specifies the safety requirements for horizontal directional drilling (HDD) machines (hereafter referred to as HDD machines) as defined in ISO 21467:2023 which are designed primarily for drilling through the earth in a mostly horizontal direction.

This document is applicable to the following HDD machine types:

— portable HDD machines;

— pedestrian-controlled HDD machines;

— towed HDD machines;

— self-propelled HDD machines;

— ride-on HDD machines;

— remote-controlled tramming HDD machines;

— skid-mounted HDD machines;

— pit-launched HDD machines;

— surface-launched HDD machines.

NOTE Some HDD machines can include a combination of types or characteristics noted above.

This document deals with all significant hazards, hazardous situations, and events relevant to the HDD machines within its scope when used as intended or under conditions of misuse reasonably foreseeable by the manufacturer, excluded hazards related to high-voltage batteries integrated in the power source system. It specifies the appropriate technical measures for eliminating or reducing risks arising from relevant hazards, hazardous situations or events during commissioning, operation, and maintenance.

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