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. www.iso.org/directives

— sensitivity level 2 (high).
4.2.4 Dual-purpose product family
There are no sensitivity levels for dual-purpose penetrants when used as a fluorescent system. However
these products may be classified as colour contrast products (see 4.2.3).
5 Testing of penetrant materials
5.1 Personnel
Testing shall be carried out by proficient, suitably trained and qualified personnel and, where
applicable, shall be supervised by competent personnel nominated by the employer or, by delegation of
the employer, the inspection company in charge of testing. To demonstrate appropriate proficiency it
is recommended that personnel be trained according to ISO 9712 or an equivalent formalized system.
Operating authorization for personnel shall be issued by the employer in accordance with a written
procedure. Non-destructive Testing (NDT) operations, unless otherwise agreed, shall be authorized by
a competent and qualified NDT supervisory individual (Level 3 or equivalent) approved by the employer.
5.2 Testing facilities
5.2.1 Type testing
Type testing shall be carried out on penetrant materials according to ISO 3452-1 with exceptions as
defined in this part of ISO 3452 to ensure their conformance to the requirements of this part of ISO 3452.
Type testing shall be carried out by a laboratory accredited in accordance with ISO/IEC 17025 for type
testing of penetrant materials.
5.2.2 Batch testing
Batch testing to the requirements of this part of ISO 3452 shall be carried out on each production batch
according to ISO 3452-1 to ensure the batch has the same properties as the corresponding type approval
sample. In the case of penetrant material packed in spray cans, the content of sulfur and halogens shall
be additionally determined according to 6.12.
Batch testing shall be carried out under a defined and maintained quality system. A system meeting the
requirements of ISO 9001 is considered suitable.
5.2.3 Process and control testing
Process and control tests to monitor the implementation of the method are described in
ISO 3452-1:2013, Annex B.
5.3 Reporting
5.3.1 Type testing
The testing laboratory (see 5.2.1) shall provide a certificate of compliance with this part of ISO 3452 and
a report that details the results obtained.
If any changes are made to the penetrant material composition, then a new type test and product identity
shall be required.
