|Significance and Use|
5.1 The ability to collect an infrared spectrum of a liquid paint as supplied in the container from the manufacturer is of significant importance when performing qualification testing. Historically, fingerprinting a material for such purpose involved separating the components of the paint and collecting an infrared spectrum of one or more of these components (vehicle, pigments, solvent, etc.) with Test Method being used for the identification of the vehicle. This unfortunately provides information only on the portion of the liquid paint analyzed whereas the technique shown in this practice provides a more complete picture of what is in the container provided. In addition, user expertise and time required to collect a spectrum is minimal versus traditional standards.
1.1 This guide covers the FT-IR fingerprinting of a liquid paint as supplied in the container without the need to separate components. Spectra collected using this technique have been found useful for paint manufacturers' quality control, trouble shooting and to verify that the paint being used is the same as the paint sample tested. This technique has been found useful for both single and multi-component coatings, the latter of which, where each component is analyzed separately (for example, amine cured epoxies and polyol/isocyanate urethanes).
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
