ISO (International Organization for Standardization) is a worldwide joint organization of national standard bodies (member organizations). The work of formulating international standards is usually completed by ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to participate in that committee. International organizations, governmental and non-governmental, may also participate in the work of the committee after contacting ISO. Draft international standards developed by the technical committee are circulated to the member bodies for voting. At least 75 % of the members voting are required to approve them for them to be adopted as international standards. International Standard ISO 148 was prepared by ISO/TC42 Technical Committee on Photography. Appendices A, B and C of this standard are suggested lists and specifications.

Limit deviation
Generally, the photosensitive surface of the film should be rolled inside, and the photosensitive surface must be rolled outside, which must be clearly marked on the packaging. The film should not be fixed on the film or lightproof film disc. The film should be rolled on the film core with both ends symmetrical. In any case, the film core should not be rolled back at one end. The total width of the roll, including any unevenness in the width of the film and any possible protrusion of the core, shall not exceed the maximum mark t plus 1 mm.

Japanese standard sizes
Limit deviation, local
The inspection of the verticality and straightness of the film edge, and the conformity of the shape and size of the film are carried out simultaneously. Randomly select a sheet film and compare it with the two standard rectangles for inspection. One of these rectangles is determined according to the minimum value specified in this standard, and the other is determined according to the maximum value specified in this standard, and they are fixed independently. Any point on the edge of the film under inspection should not fall within the small rectangle, nor should it exceed the large rectangle. 6.3 Identification of the photosensitive surface
The photosensitive surface of the sheet film can be marked with a notch or a cut corner. When holding the film, the longer than vertical, the header area is on the left, and the light side faces the operator, the notch should be on the short side near the upper corner. If a cut corner is made, it should be made at the lower left corner according to the sample orientation. The shape and number of the notch are determined by the manufacturer. These notches can also be used as additional codes to distinguish the film type. The depth of the notch should not exceed 1.6mm.
For microbubble and diazo films, the cut corner should be located in the header area, and the maximum size on both sides of the cut corner is 4mm×4mm. The cut area of the notch or the cut corner is not considered as a violation or 6.2. 6.4. Corner rounding
Sheet film may be rounded to facilitate handling. If so, the portion of the corner removed should not exceed 3 mm, and the corner should not have steps or sharp parts. 7. Header lining
The header area of roll film with a width of 105 mm or sheet film cut from roll film of this specification may be lined with a header area lining to make the writing clear or easy to preserve. The header lining may be semi-transparent or opaque, and may be self-colored or colored. The header lining should be lined in the label area of the non-photosensitive surface of the film and should not overlap with the image area. 7.1 Header width
According to TS09923:1994, three maximum widths of the header area are specified, which are: 6mm8.25mm12.25mm.
7.2 Width of header lining
The maximum width of the header lining should be equal to the minimum width of the header. The header can be 1.0mm smaller than the width of the header area (see Figure 1).3) ISO 6[48:1993 states that ISO 9923 specifies five nominal widths of headers: 4.5 mm, 6.5 mm, 9.25 mm, 12.75 mm and 17.75 mm. However, ISO 9923:1994 only stipulates the maximum width of the three types of header areas in this standard 7.

Dimensional stability
.1 Overview
This dimensional accuracy specification is applicable to the film during production and under the standard atmospheric conditions specified in ISO554, namely temperature (23±2), relative humidity (50±5)%, and balanced measurement. These dimensions may be permanently affected by aging, shrinkage or expansion changes caused by different atmospheric moisture content and humidity. However, when the package is opened within the validity period, the effect measured under the atmospheric conditions of relative humidity (23 ± 2) (50 ± 5)% and the effect measured during production shall not exceed the following provisions: 0.13mm thick cellulose tablets: +0.08%~-0.11%; 0.13mm thick ester tablets: +0.06%~0.02%; 0.06mm thick polyurethane tablets: +0.02%~0.04%; 0.02%~0.02%- ... 10%;
There are two reasons for the change in the permanent size:
) During processing, the size of the cellulose film can be caused by the loss of solvent during production. The film length will increase due to excessive stretching, while the poly film substrate will not shrink due to the loss of solvent. Temporary film base micro-cell and heat-processed type dance or silver film, during high overflow processing, there will be a phenomenon of effective space delivery. The size of this film can shrink in one direction and in another direction when the surface is moistened. Dynamic) Loss film or processed film can also shrink during storage. The solvent in the cellulose ester film base glue is actually a factor of film shrinkage. Therefore, a closed film box will reduce this shrinkage. The range listed in Table A.1 is applicable to films stored under the conditions of 26°C and 60% relative coagulation. Table A.1 Typical dimensional changes

1) For cellulose ester based films, the dimensional changes due to aging are large, mainly caused by different packaging. The small value represents the dimensional change due to aging in sealed film boxes, and the large value represents the dimensional change due to aging in free contact with air. 2) For polyester based films, the two dimensional changes due to aging represent the dimensional change range of sealed film boxes or free contact with air. 7
A.3 Temporary dimensional changes
The dimensional changes caused by normal temperature fluctuations are reversible. In this respect, raw film and processed films have similar results. The dimensional changes caused by relative temperature fluctuations are only partially, but not completely, avoidable. The film shows a hysteresis phenomenon to these changes. These changes are not completely the same for raw film and processed film. This point is particularly important during processing and subsequent drying. The size of the relevant changes can be calculated from the temperature and humidity coefficients given in Table A.1. 8

The small value represents the dimensional change due to aging in sealed film boxes, and the large value represents the dimensional change due to aging in free contact with air. 2) For polyester based films, the two dimensional changes due to aging represent the dimensional change range of sealed film boxes or free contact with air. 7
A.3 Temporary dimensional changes
The dimensional changes caused by normal temperature fluctuations are reversible. In this respect, raw film and processed films have similar results. The dimensional changes caused by relative temperature fluctuations are only partially, but not completely, avoidable. The film shows a hysteresis phenomenon to these changes. These changes are not completely the same for raw film and processed film. This point is particularly important during processing and subsequent drying. The size of the relevant changes can be calculated from the temperature and humidity coefficients given in Table A.1. 8

Dimensional stability
.1 Overview
This dimensional accuracy specification is applicable to the film during production and under the standard atmospheric conditions specified in ISO554, namely temperature (23±2), relative humidity (50±5)%, and balanced measurement. These dimensions may be permanently affected by aging, shrinkage or expansion changes caused by different atmospheric moisture content and humidity. However, when the package is opened within the validity period, the effect measured under the atmospheric conditions of relative humidity (23 ± 2) (50 ± 5)% and the size measured during production shall not exceed the following regulations: 0.13mm thick cellulose tablets: +0.08%~-0.11%; 0.13mm thick ester tablets: +0.06%~0.02%; 0.06mm thick polyurethane tablets: +0.02%~0.04%; 0.02%~0.02%- ... 10%;
There are two reasons for the change in the permanent size:
) During processing, the size of the cellulose film can be caused by the loss of solvent during production. The film length will increase due to excessive stretching, while the poly film substrate will not shrink due to the loss of solvent. Temporary film base micro-cell and heat-processed type dance or silver film, there will be a phenomenon of effective space during high overflow processing. The size of this film can shrink in one direction and in another direction when the surface is moistened. Dynamic) Loss film or processed film can also shrink during storage. The solvent in the cellulose ester film base is actually a factor of film shrinkage. Therefore, a closed film box will reduce this shrinkage. The range listed in Table A.1 is applicable to films stored under the conditions of 26°C and 60% relative coagulation. Table A.1 Typical dimensional changes

There are two reasons for the change in the permanent size:
