3.2.5.4.6 Chassis, spider arms and spindle. Hardiness value of 82 (average of 3 readings) is less than 85 as required (15 N scale). Chassis extension along spindle is 3/8 in Not listed (3/4 in extension is specified). Specimen I is No materials evaluations were performed. Specimen A except for the nominally the same as chassis, spider arms and spindle assembly. Spindle exposed with chair in low position (Similar to A in Figure 12) Not listed Arm deflection test. Applied load of 40 lbf produced a 13/16 inch deflection in left arm and a 7/8 inch deflection in the right arm (exceeds the maximum allowable deflection of 3/4 inch). Not listed |
