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

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all national standards relating to safety toecaps were withdrawn leaving the manufacturers of these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

Part 1:
Metallic toecaps
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).
2 Normative references

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 20345, ISO 20346 and the
following apply.

internal metallic toecap
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:
[1]
— statistical method, e.g. that given in ISO 5725-2 ;
ISO 22568-1:2019(E)
[3]
— mathematical method, e.g. that given in ISO/IEC Guide 98-3 ;
[4]
— uncertainty and conformity assessment as given in ISO/IEC Guide 98-4 ;
[5]
— JCGM 100:2008 .
Table 1 — Summary of requirements and number of samples
Property Subclause Number of samples
Finishing 4.2 1 sample each size right and left
Internal length 4.3.1 1 sample each size right and left
Width of flange 4.3.2 1 sample each size right and left
Impact resistance 4.4 1 sample each size right and left
Compression resistance 4.5 1 sample each size right and left
Corrosion resistance 4.6 3 samples of different sizes (left or right)
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.
