適用范圍：1.1 This standard prescribes a method for determination of aroma and/ or taste thresholds of any stimulus in a chosen medium.1.1.1 The recommendations are limited to overall selection of a suitable range of concentrations of test solutions, selected method of testing and analysis of data.1.1.2 Details of choice of sensorily neutral medium, use of compounds for dispersal of stimuli, equipment for preparation and presentation of stimuli and odourous compounds, which are individualistic are not discussed here. They should be given in any report as thresholds may vary with these parameters.1.1.3 It is recognized that the threshold value for any stimulus for a group of panelists may require revision as the sensitivity is known to improve with training and lower the value of threshold concentration.
