Interlaboratory test / proficiency test according to EN 13725:2003

With this interlaboratory test the participating laboratories have the opportunity to demonstrate their competence in odour concentration analysis according to EN 13725:2003. 

The quality parameters used are the laboratory-specific precision (represented as repeat precision) r and accuracy A determined for n-butanol. The evaluation corresponds to annex D of the standard.

All measurements are carried out as follows:

• Locally at the site of the participating laboratory;
  
  
• The odour samples are sent in pressured cans by Odournet GmbH;
  
  
• The measurements are carried out within a stated time window of 5 working days.
  
  
• Double blind organisation is optional, to ensure maximum data confidentiality
