Paints and varnishes - Determination of resistance to humidity - Part 2: Condensation (in-cabinet exposure with heated water reservoir) (ISO/DIS 6270-2:2024)

ISO 6270-2:2017 specifies the general conditions and procedures which need to be observed when testing coated test specimens in constant condensation-water atmospheres or in alternating condensation-water atmospheres, in order to ensure that the results of tests carried out in different laboratories are reproducible.
NOTE The shape and preparation of the test specimens, the duration of the test and the assessment of the test results are not covered in this document.

Peintures et vernis - Détermination de la résistance à l’humidité - Partie 2: Condensation (exposition en enceinte avec réservoir à eau chauffée) (ISO/DIS 6270-2:2024)

ISO 6270-2:2017 définit les conditions et modes opératoires généraux qui doivent être respectés lors de l'essai, sur éprouvettes revêtues, en atmosphères de condensation d'eau constante ou en atmosphères de condensation d'eau alternée, afin de s'assurer de la reproductibilité des résultats d'essais réalisés dans différents laboratoires.

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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

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 Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee
SC 9, General test methods for paints and varnishes. in collaboration with the European Committee for
Standardization (CEN) Technical Committee CEN/TC 139, Paints and varnishes, in accordance with the
Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 6270-2:2017) and ISO 11503:1995, which has
been technically revised.
The main changes are as follows:
— intermittent condensation (IC) cycle from ISO 11503 has been added;
— chamber ventilation and specimen loading requirements have been clarified;
— spacing requirements for specimens have been changed from required to recommendations, and the
objective of spacing has been clarified;
— a simplified procedure has been added for condensation verification, and the previous procedure has
been moved to informative Annex A;
— the normative references have been updated.
A list of all parts in the ISO 6270 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A
