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).

Introduction
It is widely understood that improvement of hide quality can be achieved only if quality grading norms
are applied. The primary producer as well as the whole production chain, including flaying, curing,
handling and storing, should be rewarded by better prices for improved quality.
The main purpose of this document is to provide a basis for quality grading.
This document shows a graphic representation visualizing the different grades or classes through a
schematic pictogram of a hide. There is no relation to breed, size, weight or the origin of the carcass.
