EN 13725 ILC

EN 13725 interlaboratory comparison

The EN 13725 interlaboratory test gives odour laboratories the opportunity to demonstrate their competence in odour concentration analysis according to EN 13725.
Taking part in EN 13725 proficiency testing is essential for accreditation under ISO 17025.

All measurements of the EN 13725 interlaboratory comparison are carried out:

  • locally, at the site of the participating odour laboratory
  • within five working days
  • odour samples are sent in pressurised cans by Olfasense
  • fairly and impartially – and, for complete peace of mind, we advise you to invite an independent observer to witness the proficiency test measurements

VDA 270 interlaboratory comparison

Olfasense offers regular interlaboratory comparisons for the automobile guideline VDA 270 – Determination of the odour cehaviour of materials used in the internal fittings of vehicles.

Since 2006, the VDA 270 interlaboratory comparison has been conducted by providing sets of reference materials for training. These training sets include test samples that must be prepared for evaluation as described in the VDA 270.

Trainees are then provided with the VDA 270 grade of each sample, so they can gain a better knowledge and understanding of this odour measurement scale.
