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 part of ISO 10349 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 10349-1 was prepared by Technical Committee ISO/TC 42, Photography.
This second edition cancels and replaces the first edition (ISO 10349-1:1992), which has been technically revised.
ISO 10349 consists of the following parts, under the general title Photography — Photographic-grade chemicals —
Test methods:
— Part 1: General
— Part 2: Determination of matter insoluble in water
— Part 3: Determination of matter insoluble in ammonium hydroxide solution
— Part 4: Determination of residue after ignition
— Part 5: Determination of heavy metals and iron content
— Part 6: Determination of halide content
— Part 7: Determination of alkalinity or acidity
— Part 8: Determination of volatile matter
— Part 9: Reaction to ammoniacal silver nitrate
— Part 10: Determination of sulfide content
— Part 11: Determination of specific gravity
— Part 12: Determination of density
— Part 13: Determination of pH

ISO 10349-1:2002(E)
Introduction
This part of ISO 10349 and subsequent parts deal with photographic-grade chemicals and their test methods which
are cited in other International Standards for photographic-grade chemicals. Although the ultimate criterion for
suitability of a photographic-grade chemical is its successful performance in an appropriate use test, the shorter,
more economical test methods described in subsequent parts of ISO 10349, used with those tests included in the
specific chemical standards, are generally adequate.
Over the past few years, great improvements have been made in instrumentation for various analyses. Where such
techniques have equivalent or greater precision, they may be used in place of the tests described in the appropriate
part of ISO 10349 or in the International Standards for photographic-grade chemicals. Correlation of such alternative
procedures with the given method is the responsibility of the user.
Although ISO 10349 is intended for use by individuals with a knowledge of analytical techniques, this may not always
be the case. Care has been taken to provide warnings for particularly hazardous materials. General hazard warnings
for chemicals used in ISO 10349 and other associated International Standards are given in the text as a symbol code
as a reminder in those steps detailing handling operations. More detailed information regarding hazards, handling
and use of these chemicals may be available from the manufacturer.
An index of the most current version of the International Standards dealing with photographic-grade chemicals and
test methods is given in annex A. This annex will be updated on a regular basis upon the issue of any revision or
addition to ISO 10349 or the chemical specification standards.

3 Term and definition
For the purposes of this part of ISO 10349, the following term and definition apply.
3.1
photographic-grade chemicals
chemicals commonly used in processing sensitized photographic materials, and more particularly those for which the
quality level is so specified as not to affect the fundamental performance of the photographic material
4 Safety and operational precautions
4.1 Hazard warnings
Some of the chemicals specified in the test procedures given in subsequent parts of ISO 10349 are caustic, toxic, or
otherwise hazardous. Safe laboratory practice for the handling of chemicals requires the use of safety glasses or
goggles and, in some cases, other protective apparel such as rubber gloves, face masks and aprons. Specific danger
notices are given in the test and footnotes for particularly dangerous materials, but normal precautions are required
during the performance of any chemical procedure at all times.
The first time that a hazardous material is noted in the test procedures, the hazard will be indicated by the word
“DANGER” followed by a symbol consisting of angle brackets “〈〉” containing a letter which designates the specific
hazard. A double bracket “〈〈〉〉” will be used for particularly perilous situations. In subsequent statements involving
handling of these hazardous materials, only the hazard symbol consisting of the brackets and letter(s) will be
displayed. Furthermore, for a given material, the hazard symbol will be used only once in a single paragraph.
