Introduction
This document is a type-C standard as stated in ISO 12100.

When requirements of this type-C standard are different from those which are stated in type-A or -B

standards, the requirements of this type-C standard take precedence over the requirements of the

other standards for machines that have been designed and built according to the requirements of this

type-C standard.

The vibration test codes for portable hand-held machines given in ISO 28927 are based on ISO 20643,

which gives general specifications for the measurement of the vibration emission of hand-held and

hand-guided machinery. ISO 28927 specifies the operation of the machines under type-test conditions

and other requirements for the performance of type tests. The structure/numbering of its clauses

follows that of ISO 20643.

The basic principle for transducer positioning first introduced in the EN 60745 series of European

standards is followed, representing a deviation from ISO 20643 for reasons of consistency. The

transducers are primarily positioned next to the hand in the area between the thumb and the index

finger, where they give the least disturbance to the operator gripping the machine.

In order to provide a method that gives good measurement reproducibility, this part of ISO 28927

adopts a procedure for testing impact and impulse machines using a test device based on break blocks

acting on the outer diameter of a test socket, and a free running test for other machines. The procedures

of ISO 5349 are required whenever exposure at the workplace is to be assessed.

The values obtained are type-test values intended to be representative of the average of the upper

quartile of typical vibration magnitudes in real-world use of the machines. However, the actual

magnitudes will vary considerably from time to time and depend on many factors, including the

operator, the task and the inserted tool or consumable. The state of maintenance of the machine itself

might also be of importance. Under real working conditions the influences of the operator and process

can be particularly important at low magnitudes. It is therefore not recommended that emission values

below 2,5 m/s2 be used for estimating the vibration magnitude under real working conditions in such

cases, 2,5 m/s2 is the recommended vibration magnitude for estimating the machine vibration.

If accurate values for a specific work place are required, then measurements (according to ISO 5349)

in that work situation could be necessary. Vibration values measured in real working conditions can be

either higher or lower than the values obtained using this part of ISO 28927.

The vibration test codes given in ISO 28927 supersede those given in ISO 8662, whose parts have been

replaced by the corresponding parts of ISO 28927 (see Foreword).

7 Characterization of vibration
7.1 Direction of measurement

The vibration transmitted to the hand shall be measured and reported for three directions of an

orthogonal coordinate system. At each hand position, the vibration shall be measured simultaneously

in the three directions shown in Figures 6 to 10.
7.2 Location of measurements

Measurements shall be made at the gripping zones, where the operator normally holds the machine and

applies the feed force. For machines intended for one-handed operation, it is only necessary to measure

at a single point.

The prescribed transducer location shall be as close as possible to the hand between the thumb and

index finger. This shall apply to both hand positions, with the machine held as in normal operation.

Whenever possible, measurements shall be made at the prescribed locations.

Tools of a mass of 2 kg or more may be operated using both hands, and so measurements shall be made

in two positions. For tools without a side handle, the second-hand position is on the front housing, or —

if that is not possible — on the housing, see Figures 6 to 10. For battery tools, the weight includes the

standard battery.

7.3 Magnitude of vibration
The magnitude of vibration shall be in accordance with ISO 20643:2005, 7.3.
7.4 Combination of vibration directions

The vibration total value in accordance with ISO 20643:2005, 6.4, shall be reported for both hand

positions, as applicable. It is acceptable to report and carry out tests on the hand position having the

highest reading. The vibration total value at that hand position shall be at least 30 % higher than at the

other. This result may be obtained during a preliminary test carried out by a single operator during five

test ruins.
6 © ISO 2019 – All rights reserved
---------------------- Page: 14 ----------------------
oSIST prEN ISO 28927-13:2019
ISO/DIS 28927-13:2019(E)

To obtain the vibration total value, a , for each test run, the results in each direction shall be combined

using Equation (1):
22 2
aa=+ aa+ (1)
hv hwxhwy hwz

The a value for each operator shall be calculated as the arithmetic mean of the a values for the five

hv hv

tests. For each hand position, the results from the three operators should be combined to one value, a ,

using the arithmetic mean of the three a values.

However, there are some situations where triaxial measurement may not be possible or necessary. In

such situations ISO 5349-1 requires that an appropriate multiplication factor is applied to a single-axis

measurement result to give an estimated vibration total value.

The multiplication factor used should be between 1,0 for highly dominant single-axis tools and 1,7

where the measured axis represents the vibration in all three axes. (A vibration axis is dominant when

both non-dominant axis vibration values are each less than 30 % of the dominant axis vibration value.)

Where single-axis measurements are to be used, the single axis shall be the dominant axis.

EXAMPLE Initial measurements on a nailer show that the vertical axis vibration is dominant and

that the vibration in the other axes is always less than 30 % ((Value to be checked and changed later.))

of the acceleration in the dominant axis, ahw,dominant. In this case the estimated vibration total value

is given by
22 2
aa=+(,03aa)(+ 03,)
hv hw,dominanthw,dominant hw,dominant
=+1 220×=,,31aa086
hw,dominanthw,dominant

A multiplication factor of 1,086 (rounded to 1,1) is therefore appropriate. The estimated vibration total

value will therefore be 1,1 times the dominant axis vibration value.
8 Instrumentation requirements
8.1 General
The instrumentation shall be in accordance with ISO 20643:2005, 8.1.
8.2 Mounting of transducers
8.2.1 Specification of transducer
The specification for the transducer given in 20643:2005, 7.2.1, applies.

The total mass of the transducers and mounting device shall be small enough, compared with that of

the machine, handle, etc., so as not to influence the measurement result.
This is particularly important for low-mass plastic handles (see ISO 5349-2).
8.2.2 Fastening of transducers

The transducer or mounting block used shall be rigidly attached to the surface of the handle.

In case of soft grip handles the resilient material shall be removed to attach the transducer on the rigid

surface.

oSIST prEN ISO 28927-13:2019
ISO/DIS 28927-13:2019(E)

Ideally for triaxial measurements, integrated triaxial transducers shall be used. For the two axes

aligned parallel to the vibrating surface, the measurement axes of the two transducers — or the two

transducer elements in a triaxial transducer — shall be a maximum of 10 mm from the gripping surface.

8.2.3 Mechanical Filter

It is normally necessary to use mechanical filters for measurements in accordance with this part of

ISO 28927 to prevent dc shifts. For the application of mechanical filter see ISO 5349-2:2001, Annex C.

8.3 Frequency weighting filter
Frequency-weighting shall be in accordance with ISO 5349-1.
8.4 Integration time
8.4.1 General
The integration time shall be in accordance with ISO 20643:2005, 7.4.
8.4.2 Single sequential and contact actuation

Actuation shall be performed 10 times regularly distributed over an integral time of 30 s.

8.4.3 Continual contact actuation

The machine shall be set to 80 % of its maximum repetition speed of operation. If this is not possible, the

machine shall be set to its maximum repetition speed of operation. The measurement shall be carried

out over a duration of at least 8 s.
8.5 Auxiliary equipment

For pneumatic machines, the air pressure shall be measured using a pressure gauge with an accuracy

equal to or better than 0,1 bar.

For electrical machines, the voltage shall be measured using a volt meter with accuracy equal to or

better than 3 % of the actual value.
8.6 Calibration of the measurement chain
The specifications for calibration given in ISO 20643:2005+A1: 2010, 7.6 apply.
9 Testing and operating conditions of the machinery
9.1 General

Measurements shall be carried out on a new, properly serviced and lubricated fastener driving tool.

The fastener driving tool shall be operated perpendicularly to the workpiece.

A suitable feed force shall be applied to ensure stable and smooth operation of the power tool and to

give rated performance in accordance with the manufacturer's specification.

During the test, the power tool shall be arranged so that the operator can have an upright, or almost

upright, posture and work with his forearm and upper arm at an angle between 100° and 160°. The

operator shall be able to hold the power tool comfortably during the test. See Figure 11.
