This document, together with ISO 20770-1:____, deals with all significant hazards for foundation equipment 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 B).

The requirements of this part are complementary to the common requirements formulated in ISO 20770‑1:____.

This document does not repeat the requirements from ISO 20770-1:____ but adds or replaces the requirements for application for foundation equipment.

In this document the general term “foundation equipment” covers several different types of machines used for installation and/or extracting by drilling (machines with a rotary torque greater than 35 kNm), driving, piling, vibrating, pushing, pulling or a combination of techniques, or any other way, of:

—    longitudinal foundation elements, such as concrete piles, steel beams, tubes and sheet piles;

—    injection elements as tubes and hoses;

—    casings for cast in situ;

and used for:

—    soil improvement by vibrating and soil mixing techniques;

—    vertical drainage.

NOTE      Some foundation equipment may have an additional rotary head with a torque less than 35 kNm for pre-drilling applications; this equipment is covered by this standard.

Machines with one or more of the following characteristics are not covered by this standard, but are covered by ISO 20770-2:____, including:

—    machines that have a main rotary head torque of less than 35 kNm;

—    machines that have multi-directional drilling capability;

—    machines require additional measures during the installation/extraction process (for example, adding or removing such as rods, digging tools, drilling tools).
