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 second edition cancels and replaces the first edition (ISO 6639‑1:1986), which has been technically revised.

The main changes are as follows:

— according to the insect developmental stages causing damage, the definition and general of hidden infestation has been modified;
— the sampling location, time and period have been modified;
— rapid methods in Table 1 have been modified based on ISO 6639‑4;
— some potential techniques in Table 2 have been added.

A list of all parts in the ISO 6639 series can be found on the ISO website.
