ISO 14096-1:2005 specifies procedures for the evaluation of basic performance parameters of the radiographic film digitisation process such as spatial resolution and spatial linearity, density range, density contrast sensitivity and characteristic transfer curve. They can be integrated into the system software and together with a standard reference film used for quality control of the digitisation process. This reference film provides a series of test targets for performance evaluation. The test targets are suitable for evaluating a digitisation system with a spatial resolution down to 25 micrometres, a density contrast sensitivity down to 0,02 optical density, a density range of 0,5 to 4,5 and a film size capacity of (350 x 430) mm2. This standard does not address signal processing and display of the digitised data.

ISO 14096-2:2005 specifies three film-digitisation quality classes for the requirements of non-destructive testing. The selected class depends on the radiation energy, penetrated material thickness and the quality level of the original radiographic film. ISO 14096-2:2005 does not address signal processing, display and storage of the digitised data.

This part of ISO 11699 describes a procedure for the control of the film processing systems by users by processing pre-exposed strips. These strips are pre-exposed by X-rays and are accompanied by a certificate from the film strip manufacturer. The user processes the pre-exposed strips in his film processing system and records the results. In this part of ISO 11699, Clause 4 shows the responsibility of the film strip manufacturer. The user is responsible for Clauses 5 to 8, which show compliance with the chosen film system classification.

1.1 This standard provides a practice whereby industrial radiographic imaging systems may be comparatively assessed using the concept of relative image quality response (RIQR). The RIQR method presented within this practice is based upon the use of equivalent penetrameter sensitivity (EPS) described within Practice E1025 and subsection 5.3 of this practice. Figure 1 illustrates a relative image quality indicator (RIQI) that has four different plaque thicknesses (0.015, 0.010, 0.008, and 0.005 in.) sequentially positioned (from top to bottom) on an absorber plate of a specified material and thickness. The four plaques contain a total of 14 different arrays of penetrameter-type hole sizes designed to render varied conditions of threshold visibility when exposed to the appropriate radiation. Each “EPS” array consists of 30 identical holes; thus, providing the user with a quantity of threshold sensitivity levels suitable for relative image qualitative response comparisons. There are two standard materials (steel and plastic) specified herein for the RIQI and absorber. For special applications the user may design a non-standard RIQI-absorber configuration; however the RIQI configuration shall be controlled by a drawing similar to Fig. 1. Use of a non-standard RIQI-absorber configuration shall be described in the user’s written technique and approved by the CEO. 1.2 This practice is not intended to qualify the performance of a specific radiographic technique nor for assurance that a radiographic technique will detect specific discontinuities in a specimen undergoing radiographic examination. 1.3 This practice is not intended to be used to classify or derive performance classification categories for radiographic imaging systems. For example, performance classifications of radiographic film systems may be found within Test Method E1815, and manufacturer characterization of computed radiography (CR) systems may be found in Practice E2446. However, the RIQI and absorber described in this practice are used by Practice E2446 for manufacturer characterization of computed radiography (CR) systems and by Practice E2445 to evaluate performance and to monitor long term stability of CR systems. 1.4 For high-energy X-ray applications (4 to 25 MeV), Test Method E1735 provides a similar RIQR standard practice. 1.5 The values stated in SI are to be regarded as the standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This International Standard specifies methods for determining the ISO speed and ISO average gradient of the film/process combinations used in medical and dental radiography other than mammography. Sensitometric procedures are described for films exposed directly to X-rays. The purpose of this International Standard is to provide a method for the measurement of ISO speed and ISO average gradient so that the characteristics of the film/process system can be obtained reproducibly and can also be compared with those of other systems.

This part of ISO 9236 specifies methods for the determination of the sensitometric curve shape, average gradient and speed of a single sample of a screen/film/filmholder/processing system for medical radiography. It is not applicable to special radiographic applications such as mammography, dental radiography and direct-exposing medical radiographic systems (see for example ISO 5799 [3]). The filmholder can be any means that ensures close screen/film contact and prevents the film from being exposed to ambient light. In particular, the filmholder can be a light-tight vacuum bag, as often used in the laboratory, or a radiographic cassette as used in medical radiography.

This International Standard specifies the nominal sizes, aim dimensions with tolerances, weights, and certain tests for medical radiographic cassettes, screens, and films. It includes medical hard-copy imaging films in the form of sheets, such as laser films and video. This International Standard also includes information regarding the appropriate marking of these products, and special attention is given to cassettes/screens/films used for mammography. This International Standard does not include films in roll format (see informative annex A).
