| 146 | The second is the use of dead space as a device-quality claim. A device may be marketed on a low retained volume without stating how the figure was obtained, and because no standard requires the declaration, no comparability can be assumed. Marketing figures and gravimetrically measured figures for the same product have differed.{{r|zule2013}} | 146 | The second is the use of dead space as a device-quality claim.
