| Popis: | Proficiency testing (PT) and interlaboratory comparisons (ILC) are basic tools of external quality assurance in testing and calibration laboratories. Seeking to meet the needs and expectations of all stakeholders, the Central Office of Measures (GUM) provides ILC in the field of calibration of breath alcohol analyzers. This article describes a series of twelve bilateral ILCs conducted sequentially from December 2014 until July 2016. Eleven laboratories, accredited or in the process of preparation for accreditation, participated in these comparisons. Comparisons encompassed calibration of the same Intox II EC/IR analyzer at four test points: 0.10 mg/L, 0.25 mg/L, 0.41 mg/L, 1.52 mg/L. The results of participant performance evaluation, the results of the density measurements of participants’ liquid ethanol standards and the results of correlation analysis at four calibration points are presented. Nine out of eleven participants obtained all satisfactory results. One of the remaining laboratories confirmed the effectiveness of implemented remedial actions by successful participation in repeated ILC. Laboratories with satisfactory performance confirmed the declared uncertainty. |
