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.

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.

Introduction
This part of ISO 11393 forms part of a series concerned with personal protective equipment designed
to protect against the risks arising from the use of hand-held chain-saws primarily constructed for
cutting wood.
Accidents occur due to a number of complex reasons, but a common factor is incorrect use of the chain-
saw. The importance of correct training and proper use of a chain-saw in preventing accidents cannot
be underestimated.
All parts of the upper body have been shown to be at risk when using a chain-saw.
In this part of ISO 11393, specifications for the protective coverage and performance of the upper body
protectors are given. No personal protective equipment can ensure a 100 % protection against cutting
from a hand-held chain-saw.
Nevertheless, experience has shown that it is possible to design personal protective equipment that
offers a certain degree of protection.
Different functional principles may be applied in order to give protection, such as:
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 chain-saw protective clothing. Upper body protectors
meeting this part of ISO 11393 are meant to be used whilst working off the ground, and where risk
assessment shows that there is a significant risk to be 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.

DRAFT INTERNATIONAL STANDARD ISO/DIS 11393-6:2016(E)
Protective clothing for users of hand-held chain-saws —
Part 6:
Test methods and performance requirements for upper
body protectors
1 Scope
This part of ISO 11393 specifies requirements for the protection offered by upper body protectors
against cutting by a hand-held chain-saw.
It also specifies the 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.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
upper body protector
any type of protective garment, which protects at least the specified area to the level of resistance to
cutting by a chain-saw specified within this part of ISO 11393 for the upper part of the body, e.g. jacket
3.2
front
of an upper body protector〉 part of a garment covering the forward 50 % of the upper body
circumference

3.3
rear
of an upper body protector〉 part of a garment covering the backside 50 % of the upper body
circumference
Note 1 to entry: Depending upon design and construction, and due to many layers of protective material, it can be
difficult to establish the division between the front and the rear of an upper body protector. It is nevertheless of
great importance to establish this before pre-treatment and testing.
3.4
top of shoulder
top of shoulder as shown in Figure 1
3.5
protective material
material which is designed to protect the wearer against the cutting effect of a hand-held chain-saw
Note 1 to entry: This protective material may include the cloth of the garment.
3.6
unit of protective material
cut out piece or panel of protective material consisting of all the fabric or other layers that constitute
the protective material that go into the construction of a garment
Note 1 to entry: A unit has no seams or joins within it. Units can be joined together to provide the complete
protective coverage required, before insertion and attachment to garments, but such units retain their
individuality for testing purposes.
3.7
protective coverage
area of the garment which consists of protective material
3.8
specified protective area
required protective coverage defined in this part of ISO 11393
3.9
Cut through
term describing that a saw chain has damaged and/or perforated the innermost layer of the test sample.
Damage in the innermost layer to the skin means that a hole is cut into this material or a few yarns are
visible hit by the saw
3.10
Joins
A Join in protective area is a place or line where two or more parts of the protective insert are connected
or fastened together e.g. by seams or zippers
4 Performance Requirements
4.1 General
Upper body protectors for chain-saw users shall meet an overall requirement that they are safe and fit
for the purpose. They shall meet requirements listed in 4.2 to 4.7.
4.2 Innocuousness
Upper body protectors for chain-saw users shall be designed and manufactured to provide protection
when used in accordance with the manufacturer’s instructions, without endangering the user or others.
Construction materials and incorporated substances shall meet the innocuousness requirements in
ISO 13688. They shall not endanger those coming into contact with them. The names and concentrations
