Scope

1.1 Infrared (IR) spectrophotometry involving IR microscopes, coupled with Fourier transform infrared (FTIR) spectrometers, is a valuable method of identifying polymeric fibers (that is, polypropylene, polyethylene, etc.) and rubber used in synthetic equine surfaces. FTIR may also be used to identify organic compounds and other non-metallic elements present in the binder (that is, high-oil wax) extracted from an equine surface. FTIR of wax-based binders can also detect and quantify relative degrees of binder oxidation. FTIR works by detecting and interpreting the oscillations of the atoms bonded together in the molecular structure. Infrared light absorption spectra are generated from samples tested, and these spectra are compared to libraries of known polymer spectra. For bulk fiber samples, different fibers are visually separated into groups and individual fibers from each group are tested. For extracted wax, several tests are conducted to ensure consistency. FTIR absorption spectrums for two common fibers are shown in Fig. 1. FTIR spectrum for a wax binder exhibiting oxidation peaks is shown in Fig. 2. 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.
