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 document 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 ).

This document was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 32, Electrical and electronic components and general system aspects.

This third edition cancels and replaces the second edition (ISO 20653:2013), which has been technically revised.

The main changes are as follows:

• test conditions for IPX9K test were extended, the method for measuring of the impact forced was described and tolerances were added, the visualization method for impact force with foam was added;
• details to test setup for degrees of protection against water 3, 4 and 4K were added.

Introduction

The IP codes used in this document are in accordance with IEC 60529, except in the case of codes “K”, which describe special requirements for road vehicles that are not covered by IEC 60529.

1 Scope

This document applies to degrees of protection (IP code) provided by enclosures of the electrical equipment of road vehicles. It specifies the following:

• a) designations and definitions of types and degrees of protection provided by enclosures of electrical equipment (IP codes) for the:
  • protection of electrical equipment within the enclosure against ingress of foreign objects, including dust (protection against foreign objects);
  • protection of persons against access to hazardous parts inside the enclosure (protection against access);
  • protection of electrical equipment inside the enclosure against effects due to ingress of water (protection against water);

• b) requirements for each degree of protection;

• c) tests carried out in order to confirm that the enclosure complies with requirements of the relevant degree of protection.
