Ships and marine technology — Large yachts — Measurement and assessment of the visual appearance of coatings

This International Standard specifies technical requirements for the measurement and assessment of the visual appearance of the superficial coating of large yachts in terms of gloss, colour and any other superficial defects. This International Standard is applicable to large yachts, of length, LH, as defined in ISO 8666, higher than or equal to 24 m, and in use for sport or pleasure and commercial operations. It describes the technical properties within which the final finish is to be evaluated before its acceptance.

Navires et technologie maritime — Grands yachts — Mesurage et évaluation de l'apparence visuelle des revêtements

La présente Norme internationale spécifie les exigences techniques de mesurage et d'évaluation de l'apparence visuelle des revêtements de surface des grands yachts, en termes de brillance, de couleur et de tous autres défauts de surface. Elle est applicable aux grands yachts, dont la longueur, LH, telle que définie dans l'ISO 8666, est supérieure ou égale à 24 m, destinés au sport, au loisir et aux opérations commerciales. Elle décrit les propriétés techniques servant de cadre à l'évaluation de l'état de finition final avant son acceptation.

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.

of yacht coatings.
Measurement processes are based on known generic inspection equipment that is available at the time of
producing this document. It is not the purpose of this document to provide an exhaustive list of inspection
equipment which is available at the time of publication.
