Accreditation and Quality Assurance (Accred. Qual. Assur.; "ACQUAL") publishes conceptual and practice-oriented articles on all aspects relevant to quality, transparency and reliability of measurement results in chemical and biological sciences. This is aimed at disseminating knowledge and contributing to the elimination of conceptual and technical barriers to intercontinental understanding ("CBU" and "TBU"). It is in this context that ACQUAL asks the authors for clarity in the presentation of their results by following international conventions or by defining deviations without ambiguity. The journal aims at serving the information needs of researchers, practitioners and decision makers alike. It provides problem solving for improved measurement practice, covers aspects of related education and training, and fosters cooperation between national and international bodies operating in accreditation and quality assurance of measurements in chemical and biological sciences.
