This European Standard specifies the basic procedures applied in the X-ray Powder Diffraction (XRPD) method. Many of these procedures are common to most types of diffractometer used and types of analysis mentioned in EN 13925‑1. In the interests of clarity and immediate usability more details are given for procedures using instruments with Bragg-Brentano geometry and application to phase identification. Aspects of specimen preparation and data quality assessment are included, but the standard remains non-exhaustive. It is anticipated that particular standards will address specific fields of application in more details.
