ISO 3743, all parts: Acoustics - Determination of sound power levels of noise sources - Engineering methods for special reverberation test rooms9 laboratories in Germany are accredited by DAKKS for at least one part of ISO 3743. Each lab card shows which parts it holds. From the accredited scope text: “ISO 3743 -1:2010 EN ISO 3743-1:2010 DIN EN ISO 3743-1: 2011 Acoustics - Determination of sound power levels and sound energy levels of noise sources using sound pressure - Engineering methods for smal” “ISO 3743 -1 2011-01 Akustik – Bestimmung der Schallleistungs - und Schallenergiepegel von Geräuschquellen aus Schalldruckmessungen – Verfahren der Genauigkeitsklasse 2 für kleine, transportable Quelle” “ISO 3743 -1 2010-10 Akustik – Ermittlung der Schalleistungspegel von Geräuschquellen; Verfahren der Genauigkeitsklasse 2 für kleine, transportable Quellen in Hallfeldern – Teil 1: Vergleichsverfahren”
This page is a fixed slice of the register: every ISO 3743 scope we hold for Germany. Search narrows it further by city, accreditation body, or a term from the scope text itself.
ISO/IEC 17025 is the international standard for the competence of testing and calibration laboratories. Accreditation to this standard provides independent confirmation that a laboratory operates a quality management system and is technically competent to produce valid results within its declared scope.
