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 (see www .iso .org/ directives).

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. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

iso/ foreword .html.

This document 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 3452-2:2006), which has been technically

revised.
The main changes compared to the previous edition are as follows:
— the normative references were updated;
— tables 1, 4, 8, 9 were corrected;
— a new Clause 5.1 was inserted;
— clause 6.6 was revised;
— the former Annex B was deleted;
— editorial changes were made.

SAFETY PRECAUTIONS — The materials required by this part of ISO 3452 include chemicals

which may be harmful, flammable and/or volatile. All necessary precautions shall be observed.

All relevant International, national and local regulations pertaining to health and safety,

environmental requirements, etc. shall be observed.
1 Scope

This part of ISO 3452 specifies the technical requirements and test procedures for penetrant materials

for their type testing and batch testing. This part of ISO 3452 covers the temperature range 10 °C to

50 °C. Additional tests in part 5 or part 6 of ISO 3452 may be required outside this range.

On-site control tests and methods are detailed in ISO 3452-1.
2 Normative references

The following referenced documents, in whole or in part, are normatively referenced in this document

and are indispensable for its application. For dated references, only the edition cited applies. For

undated references, the latest edition of the referenced document (including any amendments) applies.

4 Classification
4.1 Testing products

Penetrant testing products shall be classified by type, method and form in accordance with

ISO/DIS 3452-1:2019 Table 1.
4.2 Sensitivity levels
4.2.1 General

Penetrant baseline sensitivity and product family sensitivity are determined independently and one or

both of them shall be carried out.
4.2.2 Penetrant baseline sensitivity

For penetrant baseline sensitivity the penetrant is submitted with its designated remover and is tested

using a standard reference developer. The allocated penetrant sensitivity level is only valid when the

penetrant is used with the designated remover.
4.2.3 Product family sensitivity

The product family sensitivity is determined by submitting a complete set of products for assessment.

The allocated product family sensitivity level is only valid when this complete set of products is used.

4.2.4 Fluorescent systems
Sensitivity levels shall be defined by reference products:
— sensitivity level 1/2 (very low);
— sensitivity level 1 (low);
— sensitivity level 2 (medium);
— sensitivity level 3 (high);
— sensitivity level 4 (ultra-high).
Sensitivity level 1/2 applies to Type I method A only.
4.2.5 Colour contrast systems

Sensitivity levels shall be defined using the type 1 reference block in accordance with ISO 3452-3:

— sensitivity level 1 (normal);
— sensitivity level 2 (high).
4.2.6 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. For non-destructive

Testing (NDT) operations (e.g. sensitivity and washability), unless otherwise agreed 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.
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 ISO 3452-2 to ensure their conformance to the requirements.

Type testing shall be carried out by an independent laboratory having a formalised quality system and

the relevant technical competencies. ISO/IEC 17025 accreditation for the testing of penetrant materials

would satisfy this requirement.
5.2.2 Batch testing

Batch testing to the requirements of ISO 3452-2 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.

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.
5.3.2 Batch testing

Manufacturers of penetrant materials shall provide certificates of compliance with this part of ISO 3452

(for example, see EN 10204 or ISO 10474).
5.4 Tests
5.4.1 Sensitivity test

A sensitivity test shall be carried out for each individual penetrant material and/or product family.

Type testing shall be carried out according to 6.2.

For batch testing the test shall be carried out by comparison with the previously approved retain sample.

In addition for each penetrant material the following test are required.
5.4.2 Penetrants

Type and batch testing of penetrant properties shall be carried out in accordance with Table 2.
