ANSI ESD-SP15.1-2011 pdf download For the Protection of Electrostatic Discharge Susceptible Items In-Use Resistance Testing of Gloves and Finger Cots
6.5 Baseline Resistance Measurement of Operator The baseline resistance measurement is made with an ungloved operator. The reading verifies the functionality of the test system and establishes the minimum resistance of the operator only. All in-use testing should be performed at environmental conditions similar to those in which the gloves will be used. 6.5.1 This measurement shall be performed using the DC ohmmeter as specified in Section 5.3.
6.5.2 Select the test subject’s hand of preference that will eventually be used to wear the glove/finger cot. Select the thumb and/or finger(s) to be tested. Attach the wristband to the wrist of that hand. Attach the ground cord without the one megohm resistor to one input of the resistance meter. Ensure that the wristband makes a good connection with the skin. An appropriate lotion may be used to assure a good connection. If a lotion is used, use care not to contaminate the gloves/finger cots during subsequent tests.
6.5.3 Attach the Constant Area and Force Electrode (CAFE) via the banana jack to the other input of the resistance meter. See Figure 2.
6.5.4 Balance the CAFE on the fingerprint side of the thumb or first finger of choice of the hand that has the wrist strap connected to it. See Figure 2.
6.5.5 Record the resistance measurement between the electrode on the bare finger and the wrist strap after 15 seconds electrification time. Repeat the test on any other digit that is selected for testing. .
6.5.6 Clean the electrode (CAFE) with isopropyl alcohol prior to performing the fllowing steps.
6.6 Low Voltage System Resistance Test (Less than 1.0 x 105 ohms)
6.6.1 This resistance shall be measured first using an ohmmeter as specified in Section 5.3.
6.6.2 Attach the wristband to the hand that will wear the glove. Attach the wrist strap cord without the one megohm resistor to one lead of the ohmmeter. Ensure that the wristband makes a good connection with the skin.
6.6.3 Attach the (CAFE) to the other lead of the ohmmeter. See Figure 2.
6.6.4 Wear the glove and wait a minimum of 15 seconds to begin the electrical testing.
6.6.5 Balance the CAFE on the fingerprint side of the thumb or first finger of choice of the hand wearing the glove. See Figure 2.
6.6.6 Record the resistance after 15 seconds electrification time. If the resistance measured is less than 1.0 x 10° ohms, record the resistance measurement between the electrode and the
