ANSI ESD-S1.1-2006 pdf download For the Protection of Electrostatic Discharge Susceptible Items Wrist Straps
5.1.3 Reporting Report the resistance for each wrist strap.
5.2 Cuff Resistance Test Resistance of the cuff interior and exterior is determined.
5.2.1 Equipment See 5.1.1.
5.2.2 Procedure (Interior Resistance) Using the test fixture from
5.1.1. Figure 1, place a cuff around the cylinders with the cuff interior toward the cylinders and the ground cord connector on the right side and parallel to the cylinders, evenly spaced between the cylinders. Allow the .11 kg (0.25 ib) cylinder to move freely and stress the cuf. Connect the ohmmeter to the top cylinder and the ground cord connector on the cuff. Measure and record the resistance value. Repeat procedure for a total of six cutfs.
5.2.3 Procedure (Exterior Resistance) Place a cuff around the cylinders (Figure 1) with the cuff exterior toward the cylinders and the ground cord connector on the right side and parall to the cylinders, evenly spaced between the cylinders. Allow the .11 kg (0.25 Ib) cylinder to move freely and stress the cuff. Connect the ohmmeter to the top cylinder and the ground cord connector on the cuft. Measure and record the resistance value. Repeat procedure for a total of six cuffts.
5.2.4 Reporting
Report the interior resistance and exterior resistance of each cutf.
5.3 Cuff Size Requirements
Ci“sizes are determined by the cuff’s ability to fit over a specifically sized cylinder. A cuf’s ability to expand to fit over a hand, yet contract to fit snugly around a wrist is determined by ftting the cuff over specifcally sized large and small cylinders.
5.3.1 Equipment
●1 cylinder having an outside diameter of 4.3 cm (1.70 inches)
●1 cylinder having an outside diameter of 5.3 cm (2.10 inches)
●1 cylinder having an outside diameter of 8.25 cm (3.25 inches)
●1 cylinder having an outside diameter of 8.9 cm (3.50 inches)
5.3.2 Self-Adjusting Cuffs
“L arge”-sized self-adjustable expanding metal or fabric cuffs shall fit snugly onto a 5.3 cm (2.10 inch) diameter cylinder, and be capable of easily fting over a 8.9 cm (3.50 inch) diameter cylinder.
