1 This International Standard specifies a method for the identification of rubber polymers, based on infra-red spectrometric examination of both pyrolysis products (pyrolysates) and of films cast from solutions. Typical spectra can be found in the annex.
The use of attenuated total reflectance infra-red spectroscopy is not included.
2 The principle of the method implies that sample preparation, and preparation and analysis of the infra-red spectra, have to be carried out by experienced personnet and that the equipment used for the production of the spectra has to be operated according to the manufacturer's instructions for optimum performance. No details for the operation of infra-red spectrometers are included, however, in this International Standard.
3 The method specified is not intended for quantitative analysis.
