GB/T 9582-2008/ISO 7004.2002IntroductionThis standard specifies the determination of film systems for industrial radiography ISO speed, ISO average gradient and ISO slope with X and γ-ray exposure The method of G2 and G4. Many countries already have national standards for many years on the subject, and this may provide a numerical standard gauge Those different values \u200b\u200bgiven program get. Since the photographic properties of the film depends on the spectral energy distribution, so the standard specifies the determination Four representative ray source when the photographic performance. In order to reduce the differences between national standards, the X-ray tube and an X-ray generator Given mandatory minimum requirements and, in terms of (5.3.3) clearly specified ray quality. This standard provides the film with a combination of a metal screen thickness of. Photographic film Results also depend on the chemical process development time, this standard does not require the processing method, therefore, to provide a film ISO ISO sensitivity or slope value when it is necessary to use the provisions of the ray quality, processed to have a predetermined manner, which facilitates film and film Processing contrast between the different system components. GB/T 9582-2008/ISO 7004.2002 Photographic industry ray film ISO speed, ISO and ISO average gradient of slope G2 and G4 Determination (X-ray exposure and γ)1 ScopeThis standard specifies the shape of the curve of the photosensitive direct use of X-ray exposure of industrial and γ-ray film and film processing body, ISO photosensitive Degree, ISO average gradient and ISO slope determination G2 and G4's. This standard does not require the determination of the industrial-ray film with a fluorescent intensifying screen. Note. The energy unit of measurement is given in Appendix A.2 Normative referencesThe following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research Whether the latest versions of these documents.
