They are: sizing/morphological, spreading/rheological, thermal property, and hygroscopicity characterization. The result is a chart of wavelength versus absorption that is characteristic of the material (Figure 2). Surface properties, which are especially important for some specific categories of devices, such as those that contact blood, can often be observed directly using light and scanning electron microscopy (SEM). These tests may be carried out directly on material samples or on material extracts prepared under specified conditions. As is shown in Fig. Developed a neutron imaging technique that improves area resolution by 2 or more orders of magnitude over existing imaging detectors. The thickness of the layers of interest and the detection limits required (or that are achievable) are important factors in determining the best technique(s) for a given sample. The standard goes on to note that "the following should be considered for their relevance to the overall biological evaluation of the device: a) the material(s) of manufacture; b) intended additives, process contaminants and residues; c) leachable substances; d) degradation products; e) other components and their interactions in the final product; and f) the properties and characteristics of the final product.".
