4.1 General conditions to be considered in test procedures
The aim of an ACCEPTANCE TEST is to demonstrate that the specified characteristics of the EQUIPMENT lie within the specified tolerances. Some requirements are enforced by legislation.Other requirements and specifications may be in the purchase contract, in the supplier's brochure or in other standards, for example in the IEC 60601 series.
An inventory of the EQUIPMENT under test, the ACCOMPANYING DOCUMENTS， and the test protocols, shall be compiled before any ACCEPTANCE TESTS are carried out. Each item shall be identified by its MODEL OR TYPE REFERENCE (type number) and SERIAL NUMBER, and the entire inventory shall be compared with the purchase contract.
The response of non-screen dental X-ray film (NON-SCREEN FILM, rm-32-35) to a visible-light sensitometer does not match its response to X-RADIATION. It is therefore most practicable to assess the performance of a dedicated dental film processing system when EQUIPMENT is available for testing the X-RAY EQUIPMENT. A suitable test procedure is given in annex C.
RADIOGRAPHIC FILMS and film processing are vital parts in the imaging chain. It is the responsibility of the USER to ensure that these components perform in an acceptable way, for example with respect to sensitivity, contrast and absence of ARTEFACTS. A test of the performance of these components shall precede any ACCEPTANCE TEST measurements involving the IRRADIATION of RADIOGRAPHIC FILMS using the dental X-RAY EQUIPMENT.IEC 61223-3-4 pdf download.
