17、he speed of the film/process 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-
18、oral dental radiographic 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 ap

42、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 limit film bending and provide a light-tight enclosure.When X-ray attenuation is provided
43、 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 be clearly stated on the package and the recommended method shall be included in the in
44、structions 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 discomfort to the patient.Each packet shall be provided with a means for easily unwrapping film.I
45、f 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.NOTE 1 The lead foil of 0,038 mm or equivalent material provides protection from back s
46、catter 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 be used to indicate exposure technique error on a processed film.ISO 3665:2011(E) ISO 2

This does not apply to the holding tab attached to the packet.
48、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
49、 procedure and shall be able to be disinfected with a liquid disinfectant.NOTE Concern regarding the possible transmission of communicable diseases has introduced the need to disinfect film packets prior to processing in dental practice. Protection from damage by the disinfection solution can be achieved by using a protective barrier or plastic foil overwrap on each packet.
