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.
Amendment 1 to ISO 13232-3:2005 was prepared by Technical Committee ISO/TC 22, Road vehicles,
Subcommittee SC 22, Motorcycles.

Amendment 1: MATD test helmet
Global changes
Add consequential amendments to this and other parts of ISO 13232, as needed.
Page 2, Normative references
Add the following reference to the list of Normative references:
UN/ECE Regulation 22, Uniform provisions concerning the approval of protective helmets and of their visors
for drivers and passengers of motor cycles and mopeds
Page 3, Subclause 4.2
Rename 4.2 as “Motorcyclist dummy head, head skins, and helmet”
Create a new subclause 4.2.1 entitled “Head and head skins” which includes the existing text from the original 4.2.
Add the following new subclause to 4.2 and increment all subsequent figures and tables by 1:
4.2.2 Helmet
The dummy shall be fitted with a full face MATD test helmet according to the procedures described in ISO 13232-6.
The MATD helmet shall have a size designation of either small (56 cm) or medium (58 cm). The helmet shall have
a mass of 1,54 ± 0,02 kg. The MATD helmet shall have the overall length and overall width given in Figure 1. The
MATD helmet shall meet the resultant acceleration values of UN/ECE Regulation 22-05 for helmets with a non-
protective lower face cover, as in UN/ECE 22-05, 6.2 and 7.3.6. Each test helmet shall be from a production lot
that has been certified according to clause 5 herein using the procedures in clause 6 herein.

When an MATD helmet specimen from a given production lot is tested according to the procedures described in
6.10, the specified peak resultant acceleration values for each test impact location shall be as given in Table 1.

Page 8, Clause 5
Replace Clause 5 with the following:
5 Sampling of frangible components and MATD test helmets
5.1 Initial conformity of production
For certification of any new design, material specification, or manufacturing process of any frangible component
or MATD helmet and for each of the test methods described in clause 6, 10 unused components or helmets
shall be tested to establish estimates of the sample’s mean and standard deviation. For example, certification
of three different test methods would require 30 components to be tested.
The sample mean value shall be within ± 5 % of the specified value for all strengths, abdominal insert static
forces and peak resultant head form accelerations. The sample mean value shall be within ± 20 % of the
specified value for all static deflections. The sample standard deviation shall be less than 7 % of the sample
mean value for all strengths, abdominal insert static forces and peak resultant head form accelerations. The
sample standard deviation shall be less than 10 % of the sample mean value for all static deflections.
5.2 Subsequent conformity of production
Once a sample involving a specific design, material specification, and manufacturing process have been
certified, three components from each lot which is identically manufactured shall be tested to verify the
applicable characteristics specified in Table 7.
