a,b, V (a) and μL (b) as a function of temperature measured using different spectrometer designs in participating laboratories. The accepted values for the acoustic speed in water and values reported from acoustic spectroscopy (AS) measurements46 are also shown. Error bars show propagated uncertainties from those reported in the Minimum Reporting Tables by each laboratory. c,d, BLS-obtained μL (c) and V (d) of cyclohexane (cyc) relative to that of pure water measured using different BLS techniques after normalization to the Vienna–Hannover water standard (a set of complimentary high-resolution measurements on pure injection-grade water under controlled temperature conditions obtained from laboratories in Vienna and Hannover; Supplementary Section 2.9). The insets show absolute values for water (filled circles) and cyclohexane (open circles).
