New Guide for Analysis of Forensic Geological Materials by Powder X-Ray Diffraction

1. Scope

The promotion of knowledge and development of standards (test methods, guides, practices, classifications, and terminology) for, but not limited to, definitions, methods and standard reference materials for the collection, preservation, scientific examination, preparation and reports relating to physical evidence for forensic purposes; and the general practice of forensic science; and other areas as determined by the scope.
The activities of this Committee will be coordinated with other ASTM committees of ASTM and outside organizations having related interests.

Keywords

Forensic geology, soils minerals, X-Ray diffraction

Rationale

The new draft ASTM document WK 72837, entitled Standard Guide for Analysis of Forensic Geological Materials by Powder X-Ray Diffraction was drafted by consensus of the OSAC-Geological (now Trace) Materials Subcommittee and was approved to be submitted to ASTM by the OSAC Chemistry Scientific Area Committee. The goals of this document are to describe the scope of application of powder X-ray diffraction to forensic geology. The document recommends adaptations of standard practices for forensic applications and guidance for the interpretation of X-ray diffraction patterns for this application. This document provides guidance on identification of crystalline phases in geological materials alone or in mixtures. It also provides guidance for using results of powder X-ray diffraction for forensic comparisons of geological materials

The title and scope are in draft form and are under development within this ASTM Committee.
