ISO 8130-2-221 Coating powders — Part 2: Determination of gas comparative specific gravity bottle density (reference method)

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 on that committee. International governmental and non-governmental organizations liaising with ISO are also involved in this work. ISO works closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those used for further maintenance are described in Part 1 of the ISO/IEC Directive. In particular, note the different approval standards required for different types of ISO documents. This document has been drafted in accordance with the editing rules in Part 2 of the ISO/IEC Directive (see

This document has been prepared by the Technical Committee ISO/TC 35 (Paints and varnishes), Subcommittee SC 9, General Test methods for paints and discoloring, in cooperation with the Technical Committee CEN/TC 139, Paints and Varnishes of the European Committee for Standardization (CEN), in accordance with the Technical Cooperation Agreement between ISO and CEN (Vienna Agreement).

The second edition cancelled and replaced the first edition (ISO 8130-2:1992), which had been technically revised. The main changes from the previous edition are as follows:

— The scope has been edited and revised;

— Terms and definitions are added (Art. 3);

– The gas has changed from air or helium to helium or nitrogen;

— the procedure is consistent with the actual operation;

– The acceptable difference between the two results (art. 9) is given as a percentage;

— The text has been edited and revised and the normative references have been updated.

A list of all the parts in the ISO 8130 series can be found on the ISO website.
