NPU28735 Skin surface(spec.)—Sweat production; areic mass rate(proc.) = 14 g/(m2 min) |
Abbreviated form with a result |
NPU28735 Skin surface(spec.)—Sweat production; areic mass rate(proc.) = 14 g/(m2 min) |
Written expression |
The areic mass rate of Sweat production of Mr. Smith’s Skin surface(right arm) is [14] g/(m2 min). The measurement is performed according to a procedure defined by the laboratory. |
Equation

Notes
|
The anatomical topography of the skin surface must be specified by the laboratory. In this case, it is the Mr. Smith’s skin surface of the right arm. |
