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

on the ISO list of patent declarations received (see www .iso .org/patents).

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.

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.

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 11393-2 was prepared by Technical Committee ISO/TC 94, Personal safety — Protective clothing and

equipment, Subcommittee SC 13, and by Technical Committee CEN/TC 162, Protective clothing including

hand and arm protection and lifejackets in collaboration.

ISO 11393 consists of the following parts, under the general title Protective clothing for users of hand-

held chainsaws:
— Part 1: Test rig for testing resistance to cutting by a chain-saw
— Part 2 Test methods and performance requirements for leg protectors
— Part 3: Test methods for footwear
— Part 4: Test methods and performance requirements for protective gloves
— Part 5: Test methods and performance requirements for protective gaiters

— Part 6: Test methods and performance requirements for jackets with protection against cuts

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.

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.
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.

3.6
rear (of a leg protector)
backwards 50 % of the leg circumference

Note 1 to entry: Note to entry Depending upon the design and construction, and due to many layers of

clogging material, it may be difficult to establish the front and the rear of a leg protector. It is nevertheless of

great importance to establish the front and the rear before pre-treatment and testing.

3.7
Crotch

point between the legs where the two side seams, running up the inside of each leg, meets

Note 1 to entry: Note to entry Where the side seams do not lie along the edge of the trousers when they are

flattened out then the theoretical crotch point effectively becomes the point where the two edges of the trouser

converge.
3.8
Cut through

term describing that a saw chain has damaged and/or perforated the innermost layer of the test sample

3.9
Pre-treatment
standard way of preparing the samples before testing

Note 1 to entry: Note to entry This might include a number of cleaning cycles, submitting the sample to heat,

mechanical action or any other relevant exposure and is finished by conditioning.

3.10
Fly
The fastening in the front of a trouser
3.11
Protective Insert

“Protective Insert” is the term describing the fabric which is able to stop the chain by clogging, braking

or repelling the chain. It is usually placed between the outer fabric and the lining of a garment

3.12
Damage

Damage in the last layer to the skin means that a hole is cut into this material or a few yarns are visible

hit by the saw
3.13
Leggings
“Leggings” are seat-less trousers
3.14
Chaps

“Chaps” are leg protectors which cover the front of a leg and fasten around the back of the leg

3.15
Attachment

“Attachment” is the term describing the connection (usually stitching) between the protective insert

and the outer or lining fabric
3.16
Attachment force

The attachment force is the force the connection between the protective insert and the outer fabric can

withstand, independent of the way the protective insert is attached to the outer fabric
