Generic abbreviated form NPU28735 Skin surface(spec.)—Sweat production; areic mass rate(proc.) = ? g/(m2 min)
Full form with a result 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.
