Crude petroleum - Determination of water - Distillation method (ISO 9029:1990)
The precision data of this procedure have only been determined for water contents up to 1 % (V/V). Includes principle, apparatus, solvent, calibration and recovery test, sampling, procedure, expression of results, precision and test report. The distillation apparatus is shown in figures 1 and 2. The precision of the method is shown in figure 3. The sample handling is described in annex A.

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, govern-
mental 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 lnter-
national Standard requires approval by at least 75 % of the member
bodies casting a vote.
International Standard IS0 9029 was prepared by Technical Committee
ISO/TC 28, Petroleum products and lubricants.
Annex A forms an integral part of this International Standard.

WARNlNG - The use of this International Standard may involve hazardous materials, operations and
equipment. This standard does not purport to address all of the safety problems associated with its use.
It is the responsibility of the user of this standard to establish appropriate safety and health practices
and determine the applicability of regulatory limitations prior to use.
