GSR Quality Scheme - quo data Gesellschaft für Qualitätsmanagement und Statistik mbH

GSR Quality Scheme

GSR Proficiency Tests

   
From the April 2016 Final Meeting of the international PT on Forensic Determination of Shooting Distance organized by QuoData and held at the QuoData head office in Dresden. 

 

Since 2010, the quo data Gesellschaft für Qualitätsmanagement und Statistik mbH has independently organized and evaluated the annual proficiency testing of the GSR proficiency testing program (GSR quality scheme) on behalf of the European Network of Forensic Science Institutes  (ENFSI). Thereby, quo data Gesellschaft für Qualitätsmanagement und Statistik mbH is actively supported by members of the ENFSI working group "Firearms/GSR" as an advisory board. 

The GSR proficiency testing scheme, which is unique in its form worldwide, is accredited according to ISO/IEC 17043:2010 since January 2022.

Specially prepared samples for the detection and classification of typical GSR particles (containing lead, barium and antimony) are provided, and participants use their own laboratory-specific procedure for the automated detection of GSR particles via SEM/EDS according to ASTM E1588.

Based on the composition, location and size of the particles submitted by the participants, the correct detection and classification are evaluated and assessed by quo data Gesellschaft für Qualitätsmanagement und Statistik mbH.

 

For accredited laboratories - having to take part in an annual trace evidence proficiency test - this GSR quality scheme is especially important. At the moment, no equivalent GSR quality schemes are available for international proficiency testing. Results from former proficiency tests can be viewed in the archives.
