From: Critical Reliability Issues of Common Type Alcohol-Based Handrub Dispensers
| ABHR formats | ABHR exists on the market in foam, gel or liquid format. |
| ABHR composition | ABHRs contain ethanol, propanol, isopropanol or a combination of these as active ingredients, and may contain additional active ingredients. |
| Dispensed volume | The measured volume of ABHR that a dispenser actually aliquot. |
| Baseline volume | The dispensed volume aliquoted by the dispenser after 5 consecutive strokes or applications. |
| Volume loss | The difference between the baseline volume and the dispensed volume after a dedicated time of non-use (letting the dispenser to rest idle). |
| Adjusted volume | The intended volume that a dispenser should dispense (based on the user guide / manufacturer’s description) when operated it a single time (pulling the arm of the dispenser once, or in case of automatic dispenser activate the sensor once). Some dispensers can only be used with fixed nominal volume, other may provide the option to adjust the target nominal volume to be dispensed. |
| Accuracy | The difference between the adjusted volume and the dispensed volume. |
| Performance | The overall capability of a dispenser to operate according to its specification, including its time-dependent accuracy. |
