Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO technical
committees. Each member body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 1007 was prepared by Technical Committee ISO/TC 42, Photography.
This third edition cancels and replaces the second edition (ISO 1007:1995) which has been technically revised.
This revision of ISO 1007 includes the following significant additions and changes:
a) A clause for definitions has been added in order to assist the reader of this International Standard in the proper
interpretation of the information presented.
b) A specification has been added for the single-track frame-number bar-codes, specifically the relationship of the
eye-readable frame-number to its bar-code.
c) In the dual-track frame-number bar-code system, encoding of frame numbers greater than 36A has been
incorporated.
d) The element width for the dual-track frame-number bar-code has been changed to allow element widths to be
“narrower” than in the previous edition of this International Standard.
e) The magazine bar-code system has been modified to allow for additional film lengths (digit 6), as well as a
change to digit 1 for additional flexibility.
f) Since part of 9.3 (DC electrical characteristics) was judged to apply to the test device (as opposed to the
magazine itself), it has been moved to informative annex B. It is now consistent with the philosophy that test
methods generally be documented only in informative annexes.
g) The text regarding how manufacturers shall be assigned DX numbers has been improved significantly. A new
method of using the magazine bar codes has been added to allow additional flexibility.
h) Several issues that were included in the informative annexes of the second edition of this International
Standard were judged to be obsolete. They have been removed in the interest of simplifying this revision, for
example, measurements and calculations for estimating the location of film edges and measurement of velvet
stiffness.
Annex A forms a normative part of this International Standard. Annexes B and C are for information only.
INTERNATIONAL STANDARD ISO 1007:2000(E)
Photography — 135-size film and magazine — Specifications
1 Scope
This International Standard specifies the following:
� dimensions of film lengths;
� latent-image frame numbering;
� latent-image digital bar-codes to identify the film DX number;
� dimensions of daylight-loading film magazines for use with 135-size cameras;
� a magazine bar-code that identifies the film’s DX number as well as the number of exposures;
� camera auto-sensing areas, which provide an electrically readable encodement of film speed, number of
exposures, and recommended exposure latitude for use with appropriately designed cameras;
� an information panel on which the film identification, speed and number of exposures are visible through a
window in the back of appropriately designed cameras;
� film pull-out force specification;
� film-spool attachment strength specification.
This International Standard is not intended to apply to “bulk” 35-mm film used for reloading into 135-size
magazines, nor to the reloadable magazines themselves. Also, this standard does not apply to 135-size film and
magazines that are used in single-use camera applications.
2 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent editions of the normative documents indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.
ISO 1:1975, Standard reference temperature for industrial length measurements.
ISO 554:1976, Standard atmospheres for conditioning and/or testing — Specifications.
3 Terms and definitions
For the purposes of this International Standard, the following terms and definitions apply.
NOTE Several terms (e.g. leader, trailer and tongue) have been defined in the text of this International Standard.
3.1
135-size
name of the film format that uses 35 mm film, perforated on both edges, cut to standard lengths, and loaded into a
specific size magazine for loading into 135-size cameras
3.2
aim dimension
preferred dimension at which the manufacturing process will be aimed or designed
3.3
bar-code
array of parallel rectangular bars and spaces that together represent data elements or characters in a particular
symbology
NOTE 1 Bars and spaces are arranged in a predetermined pattern following unambiguous rules defined by the symbology.
NOTE 2 For more information on symbology and definitions related to bar-codes, refer to [1] in the bibliography.
3.4
basic dimension
numerical value used to describe the theoretically exact size, profile, orientation, or location of a feature or a datum
target
NOTE It is the basis from which permissible variations are established by tolerances on other dimensions, in notes, or in
feature-control frames.
3.5
colour-negative process
chemistry used to convert appropriately designed film into colour negatives for the purpose of creating colour prints
EXAMPLE C-41, CN-16, etc.
3.6
DX
term that describes a system of encoding information on 135-size film and magazines that is useful in the operation
of cameras and photofinishing equipment
NOTE This includes camera autosensing code, latent-image bar-codes, magazine bar-code and the magazine information
panel.
3.7
DX number
two-part number used to identify specific 135-size products
NOTE Part 1 is assigned by the Photographic & Imaging Manufacturers Association (PIMA) to the sensitizer. Part 2 is
assigned by the sensitizer to each product.
3.8
exposure latitude
range of exposures that yield satis
