Käesolev dokument on jõustatud ja selle kohta on avaldatud teade Eesti standardiorganisatsiooni ametlikus väljaandes. Standard on kättesaadav Eesti standardiorganisatsioonist. This Estonian standard EVS-EN 584-1:2006 consists of the English text of the European standard EN 584-1:2006. This document is endorsed on with the notification being published in the official publication of the Estonian national standardisation organisation. The standard is available from Estonian standardisation organisation. Käsitlusala: The purpose of this standard is to fix the performance of film systems. This standard is applicable for the classification of film systems in combination with specified lead screens for industrial radiography (non-destructive testing). This standard is intended to assure that the image quality of radiographs as far as this is influenced by the film system is in conformity with the requirements of European Standards such as EN 444, EN 1435 and EN Scope: The purpose of this standard is to fix the performance of film systems.

5 EN 584-1:2006 (E) Foreword This document (EN 584-1:2006) has been prepared by Technical Committee CEN/TC 138 Non-destructive testing, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by October 2006, and conflicting national standards shall be withdrawn at the latest by October This document supersedes EN 584-1:1994. EN 584 comprises a series of European Standards for industrial radiographic films which is made up of the following: EN EN Non-destructive testing Industrial radiographic film Part 1: Classification of film systems for industrial radiography Non-destructive testing Industrial radiographic film Part 2: Control of film processing by means of reference values According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. 3
6 EN 584-1:2006 (E) 1 Scope The purpose of this standard is to fix the performance of film systems. This standard is applicable for the classification of film systems in combination with specified lead screens for industrial radiography (non-destructive testing). This standard is intended to assure that the image quality of radiographs as far as this is influenced by the film system is in conformity with the requirements of European Standards such as EN 444, EN 1435 and EN This European Standard does not apply to the classification of films used with fluorescent intensifying screens. The measurement of film systems in this standard 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 EN by which the performance of film systems can be controlled under the conditions given in industry. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
