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).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

Introduction
[2]

ISO 20345, ISO 20346 and ISO 20347 are related to safety, protective and occupational footwear

which define the performance and required properties of the footwear. On introducing these standards

all national standards relating to safety toecaps were withdrawn leaving the manufacturers of these

items with no means of demonstrating the performance of their products. This document has been

prepared to allow manufacturers to demonstrate the performance level of the toecaps before being

inserted into the footwear.

Metallic toecaps complying with the requirements of this document are suitable components of “PPE

footwear”.

1 Scope

This document specifies requirements and test methods for metallic toecaps, intended to function as

components of PPE footwear (e.g. as described by ISO 20345 and ISO 20346).

3 Terms and definitions

For the purposes of this document, the terms and definitions given in ISO 20345, ISO 20346 and the

following apply.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

metallic toecap intended to be incorporated underneath the upper of footwear intended to provide

protection against mechanical impact and compression

Note 1 to entry: External toecaps were used in the past, they are not used anymore and they are not covered by

the present document.
4 Requirements for metallic toecaps
4.1 General

This document defines two types of metallic toecaps (type A and type B) to cover the various types of

footwear constructions.

For each of the required measurements performed in accordance with this document, a corresponding

estimate of the uncertainty of measurement should be evaluated. One of the following approaches

should be used:

NOTE 1 For details, see 4.2 to 4.6.

NOTE 2 The provisions of 4.2, 4.3, 4.4, 4.5 and 4.6 do not exclude a metallic toecap design incorporating perforations.

4.2 Finishing

Metallic toecaps shall be finished so as to be free from surface marks or defects and shall be free from

burrs and sharp edges.
4.3 Dimensions
4.3.1 Internal length

When measured in accordance with the method described in 5.2.1, the internal length of metallic

toecaps shall be not less than the appropriate value given in Table 2.

NOTE The above sizing system for toecaps is not identical to any sizing
system for footwear.
4.3.2 Width of flange

If metallic toecaps are formed with a flange, the inside width of the flange, e, shall be not greater than

12 mm using the test method given in 5.2.2.
4.4 Impact resistance

When metallic toecaps are tested in accordance with the method described in 5.3 at an energy level of

either (100 ± 2) J (metallic toecaps intended for protective footwear), or (200 ± 4) J (metallic toecaps

intended for safety footwear), the clearance under the toecap during the impact shall be not less than

the appropriate value given in Table 3. In addition, the metallic toecap shall not develop sharp edges or

any cracks passing through the material (i.e. through which light can be seen). During the assessment

of the metallic toecap designed with perforations the criteria whether light can be seen shall not be

applied to the perforations.
