Paints and varnishes - Evaluation of quantity and size of defects, and of intensity of uniform changes in appearance - Part 6: Assessment of degree of chalking by tape method (ISO 4628‑6:2023)
ISO 4628-6:2011 provides pictorial reference standards for designating the degree of chalking of paint coatings. It also describes a method by which the degree of chalking is rated.
Beschichtungsstoffe - Beurteilung der Menge und der Größe von Schäden und der Intensität von gleichmäßigen Veränderungen im Aussehen - Teil 6: Bewertung des Kreidungsgrades nach dem Klebebandverfahren (ISO 4628‑6:2023)
Dieses Dokument enthält Vergleichsbilder und ein Verfahren zur Bewertung des Kreidungsgrades von Beschichtungen. Es legt ebenfalls ein Verfahren zum Bewerten des Kreidungsgrades fest. Bei diesem Verfahren ist es wichtig, zwischen Abbauprodukten der Beschichtung und anhaftendem Schmutz zu unterscheiden, besonders, wenn die Kreidung nur gering ist.
WICHTIG — Für die Bestimmung des Kreidungsgrades mit dem Klebebandverfahren ist es erforderlich, Vergleichsbilder zu verwenden, die in diesem Dokument enthalten sind. Unter Berücksichtigung der Tatsache, dass elektronische Kopien dieser Vergleichsbilder unterschiedlich sein können, je nachdem, ob sie am Bildschirm betrachtet oder ausgedruckt werden, wird für Vergleichsprüfungen empfohlen, nur Vergleichsbilder aus der gedruckten Version dieses Dokumentes zu verwenden, die direkt von den ISO Mitgliedern oder deren Vertriebshändlern beschafft wurde.

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 document 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.

This fourth edition cancels and replaces the third edition (ISO 4628-6:2011), which has been technically
revised. The main changes are as follows:
— the title has been shortened;
— the definition of chalking (3.1) has been changed to the entry in ISO 4618:2023;
— the normative references have been updated.

Introduction
ISO 4628-1 specifies the system for designating the quantity and size of defects and the intensity of
uniform changes of coatings, and outlines the general principles of the system. This system is intended
to be used especially for defects caused by ageing and weathering, and for uniform changes such as
colour changes, for example yellowing.
The other parts of the ISO 4628 series provide pictorial standards or other means for evaluating
particular types of defect. As far as possible, already existing evaluation schemes have been used as the
basis.
1)
The chalking scale used in the first edition (i.e. ISO 4628-6:1990 , Figure 1), in the third edition (i.e.
1)
ISO 4628-6:2011 , Figure 1) and in this document, consists of photographic pictures of adhesive tapes
with different amounts of pigment particles adhering to them. The pigment particles are not evenly
distributed over each tape. The lower ratings in particular (i.e. 1 to 3) give the impression of cloudiness.
Nevertheless, all five ratings in the scale used in the first edition (ISO 4628-6:1990) and in this document
are sufficiently different for visual-assessment purposes.
1)
The scale used in the second edition (i.e. ISO 4628-6:2007 , Figure 1) was computer-generated. Thus,
the white dots representing the pigment particles were distributed very evenly over the tape, with
the result that not all the ratings differed sufficiently well from each other for visual assessment to be
carried out. While ratings 0,5 to 3,0 on the black background on the scale in ISO 4628-6:2007 could be
differentiated sufficiently well from each other, it was hardly possible to visually differentiate between
ratings above 3,0, especially ratings 4 and 5. On the white background, the difference between ratings
0,5, 1,0 and 1,5 was not easy to discern. The differences between ratings 1,5 to 5,0 were more evident,
however.
