ISO 10349-11:1992

Photography — Photographic-grade chemicals — Test methods — Part 11: Determination of specific gravity

Specifies a method of determining the specific gravity (relative density) of solutions used in photographic processing. Measurement is made by a hydrometer capable of measuring density to 0,001 units, after the test portion has reached thermal equilibrium with a water-bath (at 25 °C).

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
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. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
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.
International Standard IS0 10349-I 1 was prepared by Technical Com-
mittee lSO/TC 42, Photography.
IS0 10349 consists of the following parts, under the general title Pho-
- Photographic-grade chemicals - Test methods:
