Non-destructive testing - Industrial radiographic film - Part 1: Classification of film systems for industrial radiography (ISO 11699-1:2008)
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.
Zerstörungsfreie Prüfung - Industrielle Filme für die Durchstrahlungsprüfung - Teil 1: Klassifizierung von Filmsystemen für die industrielle Durchstrahlungsprüfung (ISO 11699-1:2008)
Zweck dieses Teils der ISO 11699 ist die Festlegung der Leistungsfähigkeit von Filmsystemen.
Dieser Teil der ISO 11699 ist anwendbar für die Klassifizierung von Filmsystemen in Verbindung mit festgelegten Bleifolien für die industrielle Durchstrahlungsprüfung (zerstörungsfreie Prüfung). Dieser Teil der ISO 11699 soll sicherstellen, dass die Bildgüte von Durchstrahlungsaufnahmen — soweit sie durch das Filmsystem beeinflusst wird — in Überein¬stimmung mit den Anforderungen der Internationalen Normen wie ISO 5579, ISO 17636 und EN 12681 steht.
Dieser Teil der ISO 11699 gilt nicht für die Klassifizierung von Filmen, die mit fluoreszierenden Verstärkerfolien verwendet werden. Die Messung von Filmsystemen in diesem Teil der ISO 11699 ist auf eine ausgewählte Strahlenqualität beschränkt, um die Durchführung zu vereinfachen. Die Eigenschaften von Filmen werden sich mit der Strahlungsenergie ändern, jedoch nicht die Einstufung der Filmsystemqualität.
Zusätzliche Verfahren zur Auswertung des fotografischen Prozesses werden in ISO 11699-2 beschrieben, nach der die Leistungsfähigkeit des Filmsystems unter den in der Industrie vorliegenden Bedingungen kontrolliert werden kann.
Essais non destructifs - Film pour radiographie industrielle - Partie 1: Classification des systèmes films pour radiographie industrielle (ISO 11699-1:2008)
L'ISO 11699-1:2008 a pour but de fixer les performances des syst�mes films.
L'ISO 11699-1:2008 est applicable � la classification des syst�mes films qui sont associ�s � des �crans en plomb sp�cifi�s pour la radiographie industrielle (essais non destructifs). Elle vise � garantir une qualit� d'image des radiogrammes conforme, pour autant qu'elle d�pende du syst�me film, aux exigences des Normes internationales telles que l'ISO 5579, l'ISO 17636 et l'EN 12681.
L'ISO 11699-1:2008 ne s'applique pas � la classification des films employ�s avec des �crans renfor�ateurs fluorescents. Afin de simplifier le mode op�ratoire, le mesurage des syst�mes films se limite � une qualit� de rayonnement choisie. Les propri�t�s des films varient en fonction de l'�nergie du rayonnement, mais pas le classement de qualit� du syst�me film.
Des m�thodes compl�mentaires d'�valuation du processus photographique sont d�crites dans l'ISO 11699‑2. Celles-ci permettent de contr�ler les performances des syst�mes films dans les conditions d'une application industrielle.
Neporušitveno preskušanje - Film za industrijsko radiografijo - 1. del: Klasifikacija sistemov filmov za industrijsko radiografijo (ISO 11699-1:2008)
Namen tega dela standarda ISO 11699 je določiti učinkovitost sistemov filmov. Ta del standarda ISO 11699 se uporablja za klasifikacijo sistemov filmov v kombinaciji s specificiranimi svinčenimi zasloni za industrijsko radiografijo (neporušitveno preskušanje). Namen tega dela standarda ISO 11699 je zagotoviti, da je kakovost slike radiogramov – v kolikor nanjo vpliva sistem filmov – skladna z zahtevami mednarodnih standardov, kot so ISO 5579, ISO 17636 in EN 12681. Ta del standarda ISO 11699 ne velja za klasifikacijo filmov, ki se uporabljajo s fluorescenčnimi ojačevalnimi folijami. Meritev sistemov filmov v tem delu standarda ISO 11699 je zaradi poenostavitve postopka omejena na izbrano kakovost sevanja. Lastnosti filmov se spreminjajo z energijo sevanja, ne z razvrstitvijo kakovosti sistema filmov. Dodatne metode za vrednotenje fotografskega postopka so opisane v standardu ISO 11699-2, v skladu s katerim se lahko učinkovitost sistemov filmov nadzoruje pod pogoji industrije.

iiiForeword 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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. 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. ISO 11699-1 was prepared by Technical Committee ISO/TC 135, Non-destructive testing, Subcommittee SC 5, Radiation methods. This second edition cancels and replaces the first edition (ISO 11699-1:1998), which has been technically revised. ISO 11699 consists of the following parts, under the general title Non-destructive testing — Industrial radiographic film: ⎯ Part 1: Classification of film systems for industrial radiography ⎯ Part 2: Control of film processing by means of reference values

All further parameters determining the signal, such as the modulation transfer function or the energy of the radiation, are considered to be constant. 4 Sampling and storage For product specification, it is important that the samples evaluated yield the average results obtained by users. This will require the evaluation of several different batches periodically under conditions specified in this part of ISO 11699. Prior to evaluation, the samples shall be stored in accordance with the manufacturers' recommendations for a length of time, in order to simulate the average age at which the product is normally used. The basic objective in selecting and storing samples as described above is to ensure that the film characteristics are representative of those obtained by a consumer at the time of use.

35 Test method 5.1 Preparation The film samples shall be exposed to X-rays from tungsten target tubes. Inherent filtration of the tube, together with an additional copper filter located as close to the X-ray tube target as possible, shall provide filtration equivalent to (8,00 ± 0,05) mm of copper. The potential across the X-ray tube shall be adjusted until the half-value-absorption is obtained with (3,5 ± 0,2) mm of copper. A potential of approximately 220 kV generally meets this requirement. The film system shall include a front and a back screen of 0,02 mm to 0,04 mm lead. If single coated films are used, the emulsion coated surface shall face the X-ray tube. Good film screen contact shall be ensured. Exercise care to ensure that the film specimen does not contain density variations arising from the exposing equipment (such as non-uniform beam filters or damaged, or defective lead screens) or processing system. During and after exposure, prior to processing, maintain the film specimen at the temperature of (23 ± 5) °C and relative humidity of (50 ± 20) %. The film processing chemicals and proce
