Description (English):

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.

Abstract

Overview

EN ISO 11699-1:2011 (ISO 11699-1:2008) defines how to classify industrial radiographic film systems used in non‑destructive testing (NDT). The standard establishes measurable film‑system performance parameters (film + processing + specified lead screens) so that radiographic image quality - as influenced by the film system - conforms with international radiography requirements. It applies to X‑ray/γ radiography with lead screens (0.02–0.04 mm) and explicitly excludes films used with fluorescent intensifying screens. The measurement procedure is simplified by using a selected radiation quality; film properties change with energy but not the relative ranking of film systems.

Key topics and technical requirements

Film system definition: a combination of film and its processing carried out per manufacturer instructions.
Test radiation: tungsten target X‑rays with filtration equivalent to (8.00 ± 0.05) mm Cu and half‑value absorption at (3.5 ± 0.2) mm Cu (typical tube voltage ≈ 220 kV).
Environmental controls: maintain specimens at (23 ± 5) °C and (50 ± 20) % RH before processing.
Processing control: use certified film test strips (ISO 11699‑2); speed index Sx must be within ±5 % of manufacturer certificate; developer temperature may vary ±1 °C to achieve this.
Gradient (G): slope of the film characteristic curve determined by polynomial fit to D vs. exposure over densities from 1.0 to 4.5 above base+fog. At least 12 measuring points and six independent samples are required; densitometer calibration to diffuse density up to 4.8 is mandatory.
Granularity (σD): measured with a microdensitometer at a diffuse density of 2.00 ± 0.05 above base+fog; scanning length ≥ 116 mm; circular aperture ≈ 100 ± 5 µm (or equivalent square). Granularity values are corrected to the reference density.
Uncertainty & proficiency: required measurement uncertainties (e.g., G2 ±5 %, G4 ±7 % at 95 % confidence) and periodic inter‑laboratory proficiency testing for certifying laboratories.

Applications and users

NDT laboratories and radiography service providers evaluating or certifying film systems for industrial radiography.
Film and chemical manufacturers developing and certifying film/process systems.
Quality assurance and inspection engineers who need to ensure radiographs meet image‑quality standards for weld inspection, casting inspection, and structural component examination.
Accreditation bodies and testing labs (ISO/IEC 17025) performing formal classification and audits.

EN ISO 11699‑1 is essential for organizations that rely on film‑based industrial radiography and need an objective, reproducible method to classify film systems and ensure consistent image quality.
