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.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

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.

ISO 3059 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 138, Non-destructive testing, in collaboration with ISO Technical Committee ISO/TC 135, Non-destructive testing, Subcommittee SC 2, Surface methods, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This third edition cancels and replaces the second edition (ISO 3059:2001) which has been technically revised.

Changes from the second edition include:

• updating of the normative references;
• addition of a terms and definitions clause;
• review of requirements for colour contrast and fluorescent techniques;
• reduction of verification period of irradiation and illuminance meters to 12 months;
• an editorial review of the text.

Introduction

Both penetrant and magnetic particle testing require controlled conditions for viewing indications, e.g.:

• adequate white light to achieve reliable testing with colour contrast techniques;
• adequate UV-A irradiance with minimal light for fluorescent systems.

1 Scope

This International Standard specifies the control of the viewing conditions for magnetic particle and penetrant testing. It includes minimum requirements for the illuminance and UV-A irradiance and their measurement. It is intended for use when the human eye is the primary detection aid.

This International Standard does not cover the use of actinic blue light sources.
