ISO 1920-5:2018 コンクリートの試験—パート5：密度と水の侵入深さ | ページ 2

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 ).

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. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.

This document was prepared by Technical Committee ISO/TC 71, Concrete, reinforced concrete and pre-stressed concrete, Subcommittee SC 1, Test methods for concrete.

This second edition cancels and replaces the first edition (ISO 1920-5:2004), which has been technically revised. The main changes compared to the previous edition are as follows:

• density of irregular shape specimens can also be determined using this document;
• as-received, saturated or oven-dried specimens (cast in laboratory or cores extracted from sites) can be tested for the determination of water penetration under pressure using this document.

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

1 Scope

This document specifies methods for testing the density and depth of water penetration of hardened concrete.
