The Infrared Space Observatory (ISO) observed over 2,500 objects with its three mid-infrared spectrometers, the Short Wavelength Spectrometer (SWS), the Photo-Spectrometer (PHT-S), and the Camera Circular Variable Filters (CVF). Kraemer et al. (2002) developed an infrared classification system based on the 2.4-45.2 \micron\ full-grating spectra from the SWS. Here, we present the results of the classification of the PHT-S and CVF spectra under this system. From the PHT-S observations, we classified over 1,500 spectra, which were supplemented by data from the Low Resolution Spectrometer (LRS) from IRAS in order to extend the wavelength range of the data. For the CVF spectra, the data were processed and recalibrated prior to classification. Several new categories have been added which were not represented in the original SWS-based scheme. Modifications to the classification scheme due to the shorter wavelength ranges of the PHT-S and CVF data relative to the SWS data are discussed. The classifications of objects observed by more than one instrument are compared, as are those also observed with the IRAS LRS.
