Who are we?

ISO/TC 81 is the international technical committee that is nominally responsible for creating, updating and maintaining the ISO standards for common names of pesticides (ISO 1750) and for approved names of other pesticides that do not require common names (ISO 765).

In practice, TC 81 never meets, and all of the work of preparing standards and maintaining the XML and SVG files is carried out by the ISO 1750+765 Maintenance Agency.

The committee was created in 1955 and the secretariat was assigned to and has remained with the British Standards Institution (BSI), which had been standardising common names since 1948.

Our standards

Our flagship standard is ISO 1750 Pesticides and other agrochemicals — Common names, for which the data will soon be updated annually because several new common names are required each year.

We also maintain ISO 765 Pesticides considered not to require common names and ISO 257 Pesticides and other agrochemicals — Principles for the selection of common names, which do not need frequent updates.

How do we work?

All of the work of preparing standards, maintaining up-to-date private versions of the XML and SVG files and preparing the annual updates of the XML and SVG files for customers is carried out by the ISO 1750+765 Maintenance Agency.

Proposed common names and their supporting data are submitted by pesticide manufacturers and then checked by the Maintenance Agency to ensure that they are correct and complete and that they conform to ISO 257. IUPAC systematic names are checked for conformity with the rules, structural formulae are drawn to show similarity with existing compounds, and standard InChIs and InChIKeys are generated. The proposed names are then circulated to the member bodies of ISO/TC 81 for provisional approval.

Users of ISO 1750 need to be made aware of new common names, so when they are provisionally approved they are announced on the News page of this website, with a 6-month window for objections (such as alleged infringement of trademarks) to be lodged. If there are no objections, names become “approved”.

Every 12 months, the XML file for customers is updated to incorporate the newly-approved common names and new SVG files are provided. A list of the new names is added to the News page of this website.

Want to get involved?

Standards are developed by the people who need them – that could mean you. Technical committees include experts from both standards and industry and these experts are put forward by ISO’s national members. If you want to help shape future standards in your field, contact your national member
