NF EN ISO 11699-1
Non-destructive testing - Industrial radiographic film - Part 1 : classification of film for industrial radiography
The purpose of ISO 11699-1:2008 is to establish the performance of film systems.ISO 11699-1:2008 is applicable for the classification of film systems in combination with specified lead screens for industrial radiography (non-destructive testing). ISO 11699-1:2008 is intended to ensure that the image quality of radiographs – as far as this is influenced by the film system – is in conformity with the requirements of International Standards such as ISO 5579, ISO 17636 and EN 12681.ISO 11699-1:2008 does not apply to the classification of films used with fluorescent intensifying screens. The measurement of film systems in ISO 11699-1:2008 is restricted to a selected radiation quality to simplify the procedure. The properties of films will change with radiation energy, but not the ranking of film system quality.Additional methods for evaluating the photographic process are described in ISO 11699-2, by which the performance of film systems can be controlled under the conditions given in industry.

Le présent document a pour but de fixer les performances des systèmes films. Le présent document est applicable à la classification des systèmes films qui sont associés à des écrans en plomb spécifiés pour la radiographie industrielle (essais non destructifs). Il vise à garantir une qualité d'image des radiogrammes conforme, pour autant qu'elle dépende du système film, aux exigences de normes européennes telles que l'EN 444, l'EN 1435 et l'EN 12681. Le présent document ne s'applique pas à la classification des films employés avec des écrans renforçateurs fluorescents. Dans le présent document, le mesurage des systèmes films se limite à une qualité de rayonnement sélectionnée afin de simplifier le mode opératoire. Les propriétés des films varient avec l'énergie du rayonnement mais pas la classification de la qualité des systèmes films. L'EN 584-2 décrit des méthodes complémentaires d'évaluation du processus photographique, permettant ainsi de contrôler les performances des systèmes films dans les conditions d'une application industrielle.
The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
