DIN EN ISO 3665:2013-07 EN ISO 3665:2013 (E) 3 1 ScopeThis International Standard establishes a system for the classification of intra-oral radiographic film by the speed of the film/proc
23、ess system and by the size of the film. It specifies the sensitometric characteristics of the film/process systems, the physical characteristics of the film and packets, and it describes packaging and labelling requirements.This International Standard is applicable to intra-oral dental radiographic
24、film for manual or automatic processing. It does not apply to films intended to be exposed with fluorescent intensifying screens, or films intended to be viewed primarily by reflected light.2 Normative referencesThe following referenced documents are indispensable for the application of this documen

36、he manufacturing process for the packet, there may be a slight ledge or step on the film itself. The step shall be no greater than 0,2 mm (see Figure 1).DIN EN ISO 3665:2013-07 EN ISO 3665:2013 (E) 6 21XKeyX enlarged view of the film chip1 size 2 film2 stepNOTE Maximum step 0,2 mm.Figure 1 Film corn

38、rable difference in density when compared to that portion not exposed to the safelight.DIN EN ISO 3665:2013-07 EN ISO 3665:2013 (E) 7 5.2.5 Film identification of the radiation side of the processed filmThe film shall have an indicator at or near one edge denoting the side intended to be towards the
39、 radiation source. A preferred means is an embossed dot with the raised portion indicating the irradiated side.NOTE An alternative means used by some manufacturers is to place radiopaque numbers on the packet. The number can be read correctly on the irradiated side of the film.5.2.6 Sensitometric pr
40、operties of the film5.2.6.1 The film shall exhibit a uniform response to radiation.5.2.6.2 The speed classification shall be in accordance with ISO 5799.5.2.6.3 The average gradient in accordance with ISO 5799 shall be greater than 1,50.5.2.7 Base plus fog density at the point of manufactureBase plu
41、s fog density of the film shall be no greater than 0,25.NOTE This requirement applies only to the manufacturer of the film. The manufacturer shall retain testing data and results, should national bodies require verification for audit purposes.5.2.8 Film expiry dateThe manufacturer shall use a maximu
42、m base plus fog density of 0,40 to set the expiry date of the film.NOTE A manufacturers recommended monobath process may produce an increase in fog value of 0,05.5.3 Packet requirements5.3.1 GeneralEach packet shall contain one or more sheets of radiographic film, together with the components that l
43、imit film bending and provide a light-tight enclosure.When X-ray attenuation is provided by an internal mechanism, a sheet of lead foil or other material with equivalent X-ray attenuation characteristics shall be included in each packet.If attenuation is provided by an external mechanism, this shall
44、 be clearly stated on the package and the recommended method shall be included in the instructions for use.The covering of the packets shall have high visibility under the recommended safelight illumination.The edges of the packets should be smoothly rounded and sufficiently blunt to avoid discomfor
45、t to the patient.Each packet shall be provided with a means for easily unwrapping film.If present, the lead foil or equivalent material shall be positioned on that side of the film intended to face away from the radiation source. A material other than lead shall provide the same level of attenuation
46、.NOTE 1 The lead foil of 0,038 mm or equivalent material provides protection from back scatter radiation to allow 19 lp/mm. Thicker foils can be used but do not provide any significant improvement in image quality or shielding.NOTE 2 Alternatively, a radiopaque number on the front of each packet can
47、 be used to indicate exposure technique error on a processed film.DIN EN ISO 3665:2013-07 EN ISO 3665:2013 (E) 8 5.3.2 Packet width and lengthThe maximum width or length of the packets shall not be more than 4,0 mm greater than the corresponding width or length of the film. This does not apply to th
48、e holding tab attached to the packet.5.3.3 Packet thicknessThe maximum thickness of the packet not counting any tab used for positioning shall be 2,0 mm. For interproximal film, the tab shall have a minimum length and width of 20 mm.5.3.4 Moisture protectionThe packets should be able to withstand the moisture in a mouth during an X-ray procedure and shall be able to be disinfected with a liquid disinfectant.NOTE Concern regarding the possible transmission of communicable diseases has
