DIN ISO 14835-1:2005-12

Assessing finger skin temperature, FST, over sufficient time of observation may identify the presence and extent of finger vasoconstriction in response to cold provocation produced by appropriate hand cooling. The changes in FST during hand cooling normally reflect the degree of vasoconstriction and resistance to blood flow caused by cold provocation and possibly also alterations of this physiological process. This part of ISO 14835 specifies a) the methods for measuring the finger skin temperature, FST; b) the procedures for conducting the measurements (including the performance of cold provocation tests); c) how to report the measurement results. This part of ISO 14835 is applicable to the measurement of FST in response to cold provocation for the assessment of various peripheral vascular disorders in persons exposed to hand-arm vibration, and is intended to be used together with a battery of tests for diagnosing hand-arm vibration syndrome.
