<strong>Chapter</strong> 14 <strong>Anthropometry</strong> <strong>and</strong> biomechanics HFDS 2003 (amended Oct 2009) <strong>14.</strong>5.3.2 Vertical direction of force. Required manual verticalstatic lift forces should not exceed the applicable 5th percentilepeak or mean force values given in Exhibit <strong>14.</strong>5.3.2. [Source:MIL-HDBK-759B, 1992]Explanation. Based upon NIOSH experience, the forcesfound in the source that studied young military personnelhave been reduced by 20 percent (Exhibit <strong>14.</strong>5.3.2). Themean forces given represent force over a three secondinterval, beginning two seconds after it reached aminimum value of 45 N provided that it continued toexceeded this minimum. Exhibit <strong>14.</strong>5.3.2 reflects thehigher of two trials for each condition.14-48
