A Preface
ISO (International Organization for Standardization) is a global alliance of national standards bodies (ISO member bodies). The development of international standards is usually carried out through ISO technical committees. Each member institution interested in a subject on which a technical committee has been established has the right to be represented in the committee. Government and non-governmental international organizations that liaize with standardization organizations are also involved in this work. ISO works closely with the International Electrotechnical Commission (IEC) on all matters of electrical standardization.

International standards are drafted according to the rules given in Part 3 of the ISO/IEC Directive.

The main task of the technical committee is to develop international standards. Draft international standards adopted by the Technical Committee will be circulated to member bodies for voting. Publication as an international standard requires approval by at least 75% of member institutions.

Please note that certain elements of this standard may be the subject of patent rights. ISO is not responsible for identifying any or all such patent rights.

ISO 1523 was developed jointly by the Technical committees ISO/TC 28 (Petroleum products and Lubricants) and ISO/TC 35 (Paints and varnishes).

The third edition cancels and replaces the technically revised second edition (ISO 1523:1983).

Annex A of this standard is for reference only.

ISO 1523-2002 “Determination of flash points for paints and varnishes, petroleum and related Products-closed-cup balance method”

Introduction
This standard describes one of the two closed cup balance methods for the determination of flash points in paints, varnishes, petroleum and related products, and should be read in conjunction with the second balance method ISO 3679 ([5]) when selecting the method.

The determination of flash/no-flash temperatures using the same equipment is described in ISO 1516 ([4]) in the bibliography.

Variances between the various standard designs of test equipment are minimized through specified procedures by ensuring that tests are performed only when the product under test and the air/steam mixture above it are considered to be in temperature equilibrium.

Warning – Use of this INTERNATIONAL standard may involve hazardous materials, operations and equipment. This international standard is not intended to address all safety issues associated with its use. It is the responsibility of users of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.

1 Scope
This standard specifies the method for determining the flash point of paints, varnishes, paint binders, solvents, petroleum or related products.

This standard is not applicable to water-based coatings, but can be tested using ISO 3679 ([5]) in the bibliography.

The method is suitable for use in the temperature range of -30 °C to 110 °C, depending on the purpose of the different equipment listed in Table 1.

The interpretation of the results obtained for solvent mixtures containing halogenated hydrocarbons should be considered with caution, as these mixtures may produce abnormal results.

3 Terms and definitions
For the purposes of this INTERNATIONAL Standard, where an ignition source is considered a flame, the following terms and definitions apply.

3.1 Flash point
The minimum temperature of the test section, corrected to an air pressure of 101,3 kPa, at which the application of the ignition source would cause the vapor of the test section to ignite and the flame to spread over the liquid surface under the specified test conditions
