1.1 This International Standard specifies, in accordance with ISO 10326-1, a laboratory method for measuring and evaluating the effectiveness of the seat suspension in reducing the vertical whole-body vibration transmitted to the operator of earth-moving machines at frequencies between 1 Hz and 20 Hz. It also specifies acceptance criteria for application to seats on different machines.

1.2 This International Standard is applicable to operator seats used on earth-moving machines as defined in ISO 6165.

1.3 This International Standard defines the input spectral classes required for the following earth-moving machines. Each class defines a group of machines having similar vibration characteristics:

— rigid frame dumpers > 4 500 kg operating mass1);

— articulated frame dumpers;

— scrapers without axle or frame suspension2);

— wheel-loaders > 4 500 kg operating mass1);

— graders;

— wheel-dozers;

— soil compactors (wheel type);

— backhoe-loaders;

— crawler loaders;

— crawler-dozers ≤ 50 000 kg operating mass1, 3)

— compact dumpers ≤ 4 500 kg operating mass1;

— compact loaders ≤ 4 500 kg operating mass1);

— skid-steer loader ≤ 4 500 kg operating mass1).

1.4 The following machines impart sufficiently low vertical vibration inputs at frequencies between 1 Hz and 20 Hz to the seat during operation that these seats do not require suspension for the attenuation of transmitted vibration:

— excavators, including walking excavators and cable excavators4);

1) See ISO 6016

2) For tractor scrapers with suspension, either a seat with no suspension may be used, or one having a suspension with high damping

3) For crawler dozers greater than 50 000 kg, the seat performance requirements are suitably provided by a cushion type seat

4) For excavators, the predominant vibration is generally in the fore and aft (X) axis

— trenchers;

— landfill compactors;

— non-vibratory rollers;

— milling machines;

— pipelayers;

— finishers;

— vibratory rollers;

— horizontal directional drills (HDD).

This document provides safety requirements for autonomous machines and semi-autonomous machines (ASAM) used in earth-moving and mining operations, and their autonomous or semi-autonomous machine systems (ASAMS). It specifies safety criteria both for the machines and their associated systems and infrastructure, including hardware and software, and provides guidance on safe use in their defined functional environments during the machine and system life cycle. It also defines terms and definitions related to ASAMS.

It is applicable to autonomous and semi-autonomous versions of the earth-moving machinery (EMM) defined in ISO 6165 and of mobile mining machines used in either surface or underground applications. Its principles and many of its provisions can be applied to other types of ASAM used on the worksites.

Safety requirements for general mobile EMM and mining machines, as well as operators, trainers or passengers on the machine, are given by other International Standards (e.g. ISO 20474, ISO 19296). This document addresses additional hazards specific and relevant to ASAMS when used as intended.

It is not applicable to remote control capability (covered by ISO 15817) or function-specific automated features, except when those features are used as part of ASAMS.
