Standard Test Method for Mineral Characterization of Equine Surface Materials by X-Ray Diffraction (XRD) Techniques

Importancia y uso:

5.1 Petrographic examinations are made for the following purposes:

5.1.1 To determine the mineralogy of the material that may be observed by petrographic methods (in this method, by use of XRD) and that may have a bearing on the performance of the material in its intended use.

5.1.2 To determine the relative amounts of the constituents of the sample which is essential for proper evaluation of the sample when the constituents may differ significantly in properties that have a bearing on the performance of the material in its intended use.

5.1.3 This method helps to evaluate mineral aggregate sources for suitability as a material to be used for construction, renovation, or modification of equine surfaces. The information gathered will allow for the comparison of the composition of new mineral sources with samples of other mineral aggregate from one or more sources, for which test data or performance records are available.

5.2 This method may be used by a petrographer employed directly by those for whom the examination is made. The employer should tell the petrographer, in as much detail as necessary, the purposes and objectives of the examination, the kind of information needed, and the extent of examination desired. Pertinent background information, including results of prior testing, should be made available. The petrographer’s advice and judgment should be sought regarding the extent of the examination.

5.3 This method may form the basis for establishing arrangements between a purchaser of consulting petrographic service and the petrographer. In such a case, the purchaser and the consultant should together determine the kind, extent, and objectives of the examination and analyses to be made and should record their agreement in writing. The agreement may stipulate specific determinations to be made, observations to be reported, funds to be obligated, or a combination of these or other conditions.
