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.

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).

between ISO and CEN (Vienna Agreement).

This second edition cancels and replaces the first edition (ISO 11393-2:1999), which has been technically

revised. The main changes compared to the previous edition are as follows:

— in the Introduction, the term “hand-held chainsaws primarily constructed for cutting wood” has

been added;
— the normative references have been updated;

— the terms and definitions 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.9, 3.10, 3.12, 3.14 and 3.17 have been added;

— in Clause 4, subclauses have been added, PPE for users of left-handed chainsaws has been added,

the previous “design B” has been deleted, a new “design B” has been added to describe chaps, the

definition for trousers has been specified and a definition valid for chaps has been added;

— in Clause 5, the definition has been specified;

— in Clause 6, the clause has been completely revised, pre-treatment regulation for testing has been

changed; the definitions in 6.2, 6.3, 6.5 and 6.7 have been specified, a definition valid for chaps has

been added, cuts of the smallest and largest sizes have been added, measuring of chaps has been

added, a test method ergonomic testing has been added;

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.

3.3
chaps

leg protectors (3.11) that cover the front of a leg and fasten around the waist and the back of the leg

3.4
crotch

point between the legs where the two side seams (3.17), which run up the inside of each leg, meet

Note 1 to entry: In cases where the side seams do not lie along the edge of the trousers when they are flattened

out, the theoretical crotch point effectively becomes the point where the two edges of the trousers converge.

3.5
cut-through

any visible change on the underside of the innermost layer of the test sample caused by the saw chain

3.6
damage

condition where some yarns of the protective fabric lose their position in the structure

due to a broken ladder during the pre-treatment (3.12) cycle
Note 1 to entry: The broken ladder is often caused by a broken knitting yarn.
3.7
fly
fastening in the front (3.8) of a pair of trousers
3.8
front
forward 50 % of the leg circumference
3.9
joins

place or line where two or more parts of the protective insert (3.14) are connected or fastened together,

e.g. by seams (3.17) or zippers
3.10
leggings
seat-less trousers
3.11
leg protectors

any type of protective garment that protects at least the specified protective area (3.18) to a specified

level of resistance for the leg
3.12
pre-treatment
standard way of preparing the samples before testing

Note 1 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.
3.13
protective coverage
area of the garment that is covered by protective material (3.15)
3.14
protective insert

fabric, usually placed between the outer fabric and the lining of a garment, that is able to stop the chain

by clogging, braking or repelling the chain
