This part of ISO 28927 specifies a laboratory method for measuring handtransmitted

vibration emission at the

handles of handheld,

powerdriven

saws, polishing and filing machines with reciprocating action and small

saws with oscillating or rotating action. It is a typetest

procedure for establishing the magnitude of vibration in

the gripping areas of a machine run under specified test conditions. It is intended that the results be used to

compare different models of the same type of machine.

This part of ISO 28927 is applicable to reciprocating files intended for surface finishing equipped with a file or

polishing tool, saws intended for parting sheets, plaster for medical use or wood, or equipped with a saw blade

for use on all kinds of materials, and small circular saws primarily intended for cutting metal or composite

materials (see Clause 5), whether driven pneumatically or by other means. It is not applicable to files that are

normally used with one hand on the file blade, nor to large circular saws intended for cutting wood.

NOTE To avoid confusion with the terms “power tool” and “inserted tool”, machine is used for the former throughout

this document.

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).
