ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

ISO 11393-4:2018(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.

In some areas of work with chainsaws, one third of injuries occur to the hands. However, with different

working practices few hand injuries occur. 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.

In some countries, chainsaw users adopt working practices that, together with training, make the use

of chainsaw protective gloves unnecessary. These usually include the instruction to hold the chainsaw

with both hands and to use the chain brake if it becomes necessary to stop cutting and clear away

branches, etc.

All parts of the hand (palm, back and fingers) have been shown to be at risk when using a chainsaw.

It is generally accepted for ergonomic and health and safety reasons that protecting the palm and

the underside of the fingers is not practicable. Neither is it possible to adequately protect the back

of the fingers unless a mitt is used. In this document, specifications for the protective coverage and

performance of the back of the right-hand glove and the left-hand glove are given.

For certain operations, such as tree surgery from lifts or platforms, chainsaw operators may be assisted

by other workers who also require protection from the chainsaw, particularly for their hands. The

gloves specified in this document are suitable for these workers too.

Further information is provided in Annex A on risk analysis, glove ergonomics and selection.

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. As

far as is known, all chainsaws are designed for right-handed use and, therefore, all protective clothing

designs and requirements have assumed right-handed use. Protection may not be adequate for left-

handed use.

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. It should be noted, however,

that none has yet been shown to be fully effective in gloves.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International

Standards adopted by the technical committees are circulated to the member bodies for voting.

Publication as an International Standard requires approval by at least 75 % of the member bodies

casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 11393-4 was prepared by Technical Committee ISO/TC 94, Personal safety - Protective clothing and

equipment, Subcommittee SC 13, Protective clothing.

Introduction

This part of ISO 11393 forms part of a series concerned with personal protective equipment designed to

reduce the risks arising from the use of hand-held chain-saws primarily constructed for cutting wood.

In some areas of work with chain-saws, one third of injuries occur to the hands. However, with different

working practices few hand injuries occur. 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.

In some countries, chain-saw users adopt working practices which together with training makes the

use of chain-saw protective gloves unnecessary. These usually include the instruction to hold the chain-

saw with both hands and to use the chain brake if it becomes necessary to stop cutting and clear away

branches, etc.

All parts of the hand (palm, back and fingers) have been shown to be at risk when using a chain-saw.

It is generally accepted for ergonomic and health and safety reasons that protecting the palm and the

underside of the fingers is not practicable. Neither is it possible to adequately protect the back of the

fingers unless a mitt is used. In this part of ISO 11393, specifications for the protective coverage and

performance of the back of right hand and left hand glove are given.

For certain operations such as tree surgery from lifts or platforms chainsaw operators may be assisted

by other workers who also require protection from the chainsaw and particularly to the hands. The

gloves specified in this standard are suitable for these workers also.

Further information is provided in Annex A on risk analysis, glove ergonomics and selection.

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 which offers a certain degree of protection. As far as is known, all chain-saws are designed

for right-handed use and therefore all protective clothing designs and requirements have assumed

right-handed use. Protection may not be adequate for left-handed use.
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 chain-saw protective clothing. It should be noted however

that none has yet been shown to be fully effective in gloves.

Performance Level 1 in Table 1. of EN 388
5.3 Protection against chain-saw cutting
5.3.1 Classification according to chain speed

Protection against chain-saw cutting shall be assessed in accordance with Clause 8.3 with one of the

following chain-saw speed classes designated as follows:
— class of protection 0: 16 m/s ± 0,2 m/s;

---------------------- Page: 15 ----------------------
oSIST prEN ISO 11393-4:2017

— class of protection 1: 20 m/s ± 0,2 m/s;
— class of protection 2: 24 m/s ± 0,2 m/s;
— class of protection 3: 28 m/s ± 0,2 m/s.
5.3.2 Requirements for cut resistance

When tested in accordance with Clause 8.3, no cut through is allowed in any tested specimen. Any

damage caused by the cutting chain to the final layer should be considered as cut-through.

The final classification shall be based on the lowest performance class achieved across the size range if

more than one size is tested.
5.4 Ergonomic requirements

Chain-saw protective gloves shall be designed to minimize the discomfort and inconvenience of wearing

them. They shall not have rough or hard material or edges that will be in contact with the hand, nor an

outside contour likely to catch on branches or conflict with the operation of the chain-saw.

They shall be adequately flexible and allow a firm grip to be maintained on the chain-saw handle. Gloves

shall be assessed as specified in Clause 9.

When tested according to Clause 9.2 of ISO 11393-4 the grip factor shall be not less than 80.

NOTE Risk analysis shows that the main risk when using chainsaw protective gloves is the manual dexterity

while operating with chainsaws. Beside the regular risks, covered by EN 388, it is necessary to keep the chainsaw

safety in the operator’s hand. This test is designed to evaluate the gloves performance for this risk.

6 Test specimens

One pair of each of the specimens for testing according to Clause 8.3 shall be of the smallest and biggest

size and size 9 as provided by the manufacturer. At least four pairs of gloves shall be submitted. The

complete glove is used as test specimen.

The total number of test specimens required shall be in accordance with the related requirements

given in Clause 8.3.4.
a) mandatory tests for Type 1:

— two complete pairs of gloves for each pre-treatment applied; for Design B gloves one additional
