Railway Applications - Painting of passenger rail vehicles (ISO/DIS 9466:2023)

This document defines the performance requirements and acceptance criteria for paint used in the railway sector for passenger rail vehicles and their locomotives.
It also provides guidelines for the use of a paint applicator to describe its painting processes, product selection, surface preparation, coating application, verification and inspection methods, repairs, and tests to obtain the minimum performances for the final product.
This document applies to all types of paints used on:
- railway vehicle bodies;
- on-board equipment and constituent parts.

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.
