Overview
EN 13925-2:2003 is a CEN standard that specifies procedures for X‑ray Powder Diffraction (XRPD) used in non‑destructive testing (NDT) of polycrystalline and amorphous materials. It complements EN 13925‑1 (General principles) and gives practical, immediately usable guidance - with greater detail for instruments using Bragg‑Brentano geometry and for phase identification. The standard covers specimen preparation, data collection, and data processing/analysis while recognising that it is non‑exhaustive and that specific applications may require additional standards.
Key topics and technical requirements
- Specimen preparation
- Recommendations on lateral specimen size and ensuring the specimen intercepts the full incident beam.
- Guidance for block specimens (surface flatness, polishing and mounting) and powder specimens (thin-layer preparation, handling of small sample quantities).
- Consideration of specimen displacement, thickness and transparency effects and use of internal standards to detect/correct these effects.
- Treatment of reactive samples and measurements under non‑ambient conditions.
- Data collection
- General considerations for XRPD measurements, choice of angular range, and appropriate mode of data collection.
- Parameters relevant to data quality (counting statistics, instrumental configuration, geometry).
- Data processing and analysis
- Background subtraction, peak searching, profile decomposition and peak‑fitting.
- Phase identification, indexing, lattice‑parameter refinement and other XRPD analyses (e.g., crystallite size, microstrain as outlined in EN 13925‑1).
- Quality assessment and reporting
- Informative annexes include a report form example, a typical procedure scheme, analytical functions for profile fitting, and methods to test internal consistency of XRPD data.
- Radiation protection
- The standard reiterates the need to follow national radiation safety limits or ICRP recommendations where national rules are absent.
Applications and users
- Who uses EN 13925‑2: NDT laboratories, quality assurance and control teams, materials scientists, research laboratories and industrial facilities employing XRPD for routine or research analyses.
- Practical applications: phase identification, routine quality control of powders and bulk materials, verification of crystalline/amorphous phases, preliminary lattice parameter checks and establishing consistent XRPD procedures across laboratories and instruments.

However excessive milling, giving crystallite dimensions below about 0,5 mm, maycause line broadening and significant changes to the intrinsic characteristics of the specimen, such as:¾ sample contamination by particles abraded from the milling instruments (e.g. mortar, pestle, balls etc.);¾ partial amorphisation of the near-surface region of the sample particles;¾ transition to different polymorphic crystallographic forms;SIST EN 13925-2:2004
