Significance and Use
5.1 Determination of the percentage of KEE compound in sheet roofing is of concern to many specifiers and building owners. Method A, the faster method, is best used for quality control. Method B may apply better to research and development, or investigative work.
1.1 This test method pertains to the determination of the relative contents of Ketone-Ethylene-Ester (KEE) and Polyvinyl Chloride (PVC) after their extraction from reinforced roofing membranes, or fabrics. Based on Proton Nuclear Magnetic Resonance Spectroscopy (1H-NMR), the method allows for the quantification of PVC with respect to an internal standard. The KEE content is then obtained by difference. The test method is not applicable to membranes or blends that contain high molecular weight polymers other than PVC and KEE.
1.2 Units—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.
