ISO 8130-2-2021 “Powder coatings – Part 2: Measurement of density by gas comparative gravity bottle method (arbitration method)”

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.

The procedures used to develop this document as well as those used for further maintenance are described in Part 1 of the ISO/IEC Directive. In particular, attention should be paid to the different approval criteria required for different types of ISO documents. This document has been drafted in accordance with the editorial rules of Part 2 of the ISO/IEC Directive (see

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

The second edition cancels and replaces the first edition (ISO 8130-2:1992), which has been technically revised. Compared with the previous edition, the main changes are as follows:

— Scope has been edited and revised;

– Added terms and definitions (Article 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 two results (article 9) is given as a percentage;

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

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