Conveyor belts — Test atmospheres and conditioning periods

This document specifies the temperature, humidity and time conditions used for the conditioning and testing of all types of conveyor belt, irrespective of whether they have plastics or rubber covers. It also specifies the requirements for the time interval to be observed between production and testing of conveyor belt test pieces. Special conditions applicable to a particular test or material or simulating a particular climatic environment are not included.

Courroies transporteuses — Atmosphères d'essai et durées de conditionnement

L'ISO 18573:2012 spécifie les conditions de température, d'humidité et de durée pour le conditionnement et les essais de tous les types de courroies transporteuses, qu'elles aient des revêtements en plastique ou en caoutchouc. Elle spécifie également les délais à respecter entre la production et les essais des éprouvettes de courroies transporteuses. Les conditions particulières applicables à un essai ou matériau donné ou simulant un environnement climatique particulier ne sont pas incluses.

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 third edition cancels and replaces the second edition (ISO 18573:2012), of which it constitutes a minor
revision. The changes are as follows:
— Clause 2 and the Bibliography have been updated.
— Clause 3 has been updated.

Introduction
The conditioning of test pieces prior to testing is commonly accepted as an essential practice in most, but not
necessarily all, methods of test. Its purpose is to provide a common ground base for the commencement of the
test and to remove an unnecessary variable in the search for th
