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).

This second edition cancels and replaces the first edition (ISO 1920‑3:2004), which has been technically revised.

The main changes compared to the previous edition are as follows:

— tolerances of specimens and moulds have been redefined;
— the concept of preparation and filling has been is redrafted;
— preferred methods of compaction on the basis of slump value have been included and defined;
— the capping of cylindrical specimens for compressive strength has been included and defined;
— the curing of test specimens under hot climate has been defined.

A list of all parts in the ISO 1920 series can be found on the ISO website.
