ISO 11393-6:2018(E)
Introduction
This document forms part of a series concerned with personal protective equipment (PPE) designed
to protect against the risks arising from the use of hand-held chainsaws primarily constructed for
cutting wood.
Accidents occur due to a number of complex reasons, but a common factor is incorrect use of the
chainsaw. The importance of correct training and proper use of a chainsaw in preventing accidents
cannot be underestimated.
All parts of the upper body have been shown to be at risk when using a chainsaw. In this document,
specifications for the protective coverage and performance of the upper body protectors are given.
No PPE can ensure a 100 % protection against cutting from a hand-held chainsaw. Nevertheless,
experience has shown that it is possible to design PPE that offers a certain degree of protection.
Different functional principles may be applied in order to give protection. These include:
a) chain slipping: on contact the chain does not cut the material;
b) clogging: fibres are drawn by the chain into the drive sprocket and block chain movement;
c) chain braking: fibres have a high resistance to cutting and absorb rotational energy, thereby
reducing the chain speed.
Often more than one principle is applied in chainsaw protective clothing. Upper body protectors in
accordance with this document are meant to be used while working off the ground, and where risk
assessment shows that there is a significant risk of being cut by the moving chain on the upper part of
the body, such as when working from a sky lift and carrying out tree surgery.

3.6
protective material
material that is designed to protect the wearer against the cutting effect of a hand-held chainsaw
Note 1 to entry: The protective material may include the cloth of the garment.
3.7
rear
part of a garment covering the backside half of the upper body circumference
Note 1 to entry: Depending upon design and construction, and due to many layers of protective material (3.6), it
can be difficult to establish the division between the front (3.3) and the rear of an upper body protector (3.11). It
is nevertheless of great importance to establish this before pre-treatment and testing.
3.8
specified protective area
minimum required protective coverage (3.5)
3.9
top of shoulder
uppermost line of the shoulder of the upper body protector (3.11)
Note 1 to entry: The top of the shoulder is shown in Figure 1.
3.10
unit of protective material
cut-out piece or panel of protective material (3.6) consisting of all the fabric or other layers that constitute
the protective material that goes into the construction of a garment without any joins within it
Note 1 to entry: Units can be joined together to provide the complete protective coverage (3.5) required, before
insertion and attachment to garments, but such units retain their individuality for testing purposes.
3.11
upper body protector
any type of protective garment that protects, at least, the specified area to the level of resistance against
cutting by a chainsaw as specified for the upper part of the body

ISO 11393-6:2018(E)
4.6.2 Other changes as a consequence of cleaning
After cleaning according to the manufacturer’s instructions, and after cleaning one sample according
to 6.2.2 at 60 °C and spin-drying, and examining according to 6.5, there shall be no damage in the
protective material due to cleaning, except for the damage caused by the cut test.
4.7 Resistance to chainsaw cutting
When tested according to Clause 9, no cut-through is allowed in any test specimen.
4.8 Requirements for the attachment of protective padding and the strength of closures
The protective material shall be permanently attached to the garment. Attachment shall be continuous
along all the edges of the protective material, except around the cuff. When tested according to
Clause 10, the attachment shall resist at least a force of 150 N for each test specimen.
5 Classification according to chain speed
Testing in accordance with this document shall be carried out at one of the following four speeds with
classes assigned as follows:
a) class 0 (16,0 ± 0,2) m/s;
b) class 1 (20,0 ± 0,2) m/s;
c) class 2 (24,0 ± 0,2) m/s;
d) class 3 (28,0 ± 0,2) m/s.
6 Test methods
6.1 General
Measuring instruments, unless otherwise specified, shall be accurate to ±2 % of the pass/fail level of
the characteristic being measured.
For each of the required sequences of measurements performed in accordance with this document, a
corresponding estimate of the uncertainty of the final result shall be determined. This uncertainty,
U , shall be given in the test report in the form U = ±X. It shall be used in determining whether a
m m
pass performance has been achieved. If the final result minus U is below the pass level when the
m
requirement that a certain value shall be exceeded, the sample shall be deemed to have failed.
6.2 Pre-treatment
6.2.1 Cleaning
Before testing, the test specimens shall be pre-treated by cleaning. The cleaning shall be in accordance
with the manufacturer’s instructions, on the basis of standardized processes. If the total number
of cleaning cycles is not specified in the manufacturer’s instructions, five cleaning cycles shall be
performed. This shall be reflected in the information supplied by the manufacturer. If the manufacturer
includes instructions for washing and dry-cleaning, the number of samples indicated in 6.3 for dry
cleaning shall be dry-cleaned and the number of samples indicated in 6.3 for washing shall be washed. If
only dry-cleaning is allowed, the number of samples indicated in 6.3 for that case shall be dry-cleaned.
If only washing is allowed, the number of samples indicated in 6.3 for that case shall be washed.
After each cleaning, the upper body protectors shall be reshaped by hand, but not by ironing.
ISO 11393-6:2018(E)
Line drying after washing shall be carried out in an environment maintained at a temperature of
(30 ± 15) °C and at a relative humidity of (30 to 70) % RH.
If tumble-drying is permitted by the manufacturer’s care instructions, the garment shall be tumble-
dried after each washing cycle.
If the manufacturer doesn’t give an indication to wash the garment before first use, the test laboratory
shall test one sample unwashed. This sample shall be in addition to the samples specified in 6.3.
NOTE Manufacturers typically indicate one or more of the methods given in ISO 6330, ISO 3175-2, ISO 3175-3,
ISO 3175-4, ISO 15797 or an equivalent standardized processes for cleaning.
6.2.2 Pre-treatment for testing the effect of temperature and spinning on the structure of the
protective insert
Where washing is allowed by the manufacturer’s care instructions, before testing according to 6.5 and
Clause 9, one of the specimens shall be washed five times according to the manufacturer’s instructions,
except that the washing temperature shall be 60 °C and the specimens spin-dried at (500 ± 20) r/min.
This sample shall be selected from the samples specified in 6.3.
6.3 Number of test specimens
A set of upper body protectors shall be taken that is sufficient to complete all the tests. Note that if
two types of pre-treatments are specified, the testing and the numbers of upper body protectors are
effectively doubled and two sets are required. Upper body protectors that have been used to assess
dimensional stability, protective coverage and ergonomic requirements may be used for cut testing if it
has not been necessary to cut them up for these measurements.
The number of garments required for cut testing depends on the number of units of protective material
present within them and whether there are any joins or seams between different protective material
units, such as between the body and the sleeve. Only one test cut shall be carried out on each unit of
protective material. Therefore, at least three garments are required for cut testing if the design includes
a fastening down the centre front of the garment, but no seams between the protective material on the
body and in the sleeve. For a design incorporating only one unit of protective material, six garments are
required for cut testing. Additional samples in different sizes can be required to perform the ergonomic
assessment.

ISO 11393-6:2018(E)
Introduction
This document forms part of a series concerned with personal protective equipment (PPE) designed
to protect against the risks arising from the use of hand-held chainsaws primarily constructed for
cutting wood.
Accidents occur due to a number of complex reasons, but a common factor is incorrect use of the
chainsaw. The importance of correct training and proper use of a chainsaw in preventing accidents
cannot be underestimated.
All parts of the upper body have been shown to be at risk when using a chainsaw. In this document,
specifications for the protective coverage and performance of the upper body protectors are given.
No PPE can ensure a 100 % protection against cutting from a hand-held chainsaw. Nevertheless,
experience has shown that it is possible to design PPE that offers a certain degree of protection.
Different functional principles may be applied in order to give protection. These include:
a) chain slipping: on contact the chain does not cut the material;
b) clogging: fibres are drawn by the chain into the drive sprocket and block chain movement;
c) chain braking: fibres have a high resistance to cutting and absorb rotational energy, thereby
reducing the chain speed.
Often more than one principle is applied in chainsaw protective clothing. Upper body protectors in
accordance with this document are meant to be used while working off the ground, and where risk
assessment shows that there is a significant risk of being cut by the moving chain on the upper part of
the body, such as when working from a sky lift and carrying out tree surgery.

Performance requirements and test methods for upper
body protectors
1 Scope
This document specifies the performance requirements, test methods, design requirements,
identification and marking information for upper body protectors that offer protection against cutting
by hand-held chainsaws.
It also specifies procedures for sampling and pre-treatment of upper body protectors, the measurement
of the protective coverage, the apparatus and test methods for assessing resistance to cutting, and the
practical performance test for evaluating ergonomic properties.
Guidance on chainsaw use and the selection of appropriate upper body protectors is given in Annex A.

6 Test methods
6.1 General
Measuring instruments, unless otherwise specified, shall be accurate to ±2 % of the pass/fail level of
the characteristic being measured.
For each of the required sequences of measurements performed in accordance with this document, a
corresponding estimate of the uncertainty of the final result shall be determined. This uncertainty,
U , shall be given in the test report in the form U = ±X. It shall be used in determining whether a
m m
pass performance has been achieved. If the final result minus U is below the pass level when the
m
requirement that a certain value shall be exceeded, the sample shall be deemed to have failed.
6.2 Pre-treatment
6.2.1 Cleaning
Before testing, the test specimens shall be pre-treated by cleaning. The cleaning shall be in accordance
with the manufacturer’s instructions, on the basis of standardized processes. If the total number
of cleaning cycles is not specified in the manufacturer’s instructions, five cleaning cycles shall be
performed. This shall be reflected in the information supplied by the manufacturer. If the manufacturer
includes instructions for washing and dry-cleaning, the number of samples indicated in 6.3 for dry
cleaning shall be dry-cleaned and the number of samples indicated in 6.3 for washing shall be washed. If
only dry-cleaning is allowed, the number of samples indicated in 6.3 for that case shall be dry-cleaned.
If only washing is allowed, the number of samples indicated in 6.3 for that case shall be washed.
After each cleaning, the upper body protectors shall be reshaped by hand, but not by ironing.
ISO 11393-6:2018(E)
Line drying after washing shall be carried out in an environment maintained at a temperature of
(30 ± 15) °C and at a relative humidity of (30 to 70) % RH.
If tumble-drying is permitted by the manufacturer’s care instructions, the garment shall be tumble-
dried after each washing cycle.
If the manufacturer doesn’t give an indication to wash the garment before first use, the test laboratory
shall test one sample unwashed. This sample shall be in addition to the samples specified in 6.3.
NOTE Manufacturers typically indicate one or more of the methods given in ISO 6330, ISO 3175-2, ISO 3175-3,
ISO 3175-4, ISO 15797 or an equivalent standardized processes for cleaning.
6.2.2 Pre-treatment for testing the effect of temperature and spinning on the structure of the
protective insert
Where washing is allowed by the manufacturer’s care instructions, before testing according to 6.5 and
Clause 9, one of the specimens shall be washed five times according to the manufacturer’s instructions,
except that the washing temperature shall be 60 °C and the specimens spin-dried at (500 ± 20) r/min.
This sample shall be selected from the samples specified in 6.3.
6.3 Number of test specimens
A set of upper body protectors shall be taken that is sufficient to complete all the tests. Note that if
two types of pre-treatments are specified, the testing and the numbers of upper body protectors are
effectively doubled and two sets are required. Upper body protectors that have been used to assess
dimensional stability, protective coverage and ergonomic requirements may be used for cut testing if it
has not been necessary to cut them up for these measurements.
The number of garments required for cut testing depends on the number of units of protective material
present within them and whether the
