GSR Quality Scheme

GSR proficiency tests


Signing of agreement - 3rd September 2009,

On behalf of the European Network of Forensic Science Institutes (ENFSI), international proficiency tests on identification of gunshot residue (GSR) have been analyzed for several years. Since 2009 quo data is independently realizing the organisation and analysis of annual proficiency tests of the GSR quality scheme. Thereby members of the ENFSI expert working group "Firearms/GSR" will support quo data as an advisory board. For accredited laboratories - that have 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.

GSR2011 - Status quo

GSR2011 is completed. The individual certificates and the Final Report have been provided to the participants. The documents are also available in the password protected area of the website.

The results of the proficieny test were one of the subjects of the 18^th Annual meeting of the ENFSI Expert Working Group Firearms/GSR, in Lisbon, from October 25^th to October 28^th, 2011. Mr. Baldauf from quo data participated in the meeting.

GSR2012 is going to start soon. Interested parties will be informed by e-mail. Further information will be provided on this website.
