21、troduction X-ray powder diffraction (XRPD) is a powerful Non Destructive Testing (NDT) method for determining a range of physical and chemical characteristics of materials. These include the type and quantities of phases present, the crystallographic unit cell and structure, crystallographic texture
22、, macrostress, crystallite size and micro-strain, and the electron radial distribution function. This standard aims to describe the general aspects of the XRPD technique and its applications but not to define a specific or detailed standard for each field of application or type of analysis. The main
23、 purposes of the standard are therefore: - to provide practical guidance, unified concepts and terminology for use of the XRPD technique in the area of Non Destructive Testing with general information about its capabilities and limitations of relevance to laboratories working at different levels of
24、sophistication, from routine testing to research; - to provide a basis for quality assurance in XRPD laboratories allowing performance testing and monitoring of instruments and the comparison of results from different instruments; - to provide a general basis (without imposing specifications) for fu
