Abstract
This article brings practical guidance for organization of interlaboratory comparisons (ILCs) with small number of participants (n?=?2–7) that is not arranged by a proficiency testing provider. The methodological guideline aims to provide practical advices in following technical requirements of small ILC organization: design of a scheme, preparation, packaging and distribution of ILC test items, instructions for participants, evaluation of results and participants’ performance, and participation report. The determination of the assigned value and standard deviation for proficiency assessment is also covered and is accompanied by the practical example where the assigned value is established using order statistics.
期刊介绍：
Accreditation and Quality Assurance has established itself as the leading information and discussion forum for all aspects relevant to quality, transparency and reliability of measurement results in chemical and biological sciences. The journal serves the information needs of researchers, practitioners and decision makers dealing with quality assurance and quality management, including the development and application of metrological principles and concepts such as traceability or measurement uncertainty in the following fields: environment, nutrition, consumer protection, geology, metallurgy, pharmacy, forensics, clinical chemistry and laboratory medicine, and microbiology.
