After ESD protective equipment and materials are installed and in their actual use locations, these compliance verification test methods are recommended to provide a baseline for comparison with future compliance verification tests.
The objective of these test methods is to identify if significant performance changes in ESD equipment and materials have occurred over time. The wide variety of ESD protective equipment and materials, and the environment in which they are used, may require test setups different from those described in this technical report.
Users of this technical report may need to adapt the test method and setups as required to produce meaningful data for their own application.
Organizations who perform these tests will also need to determine the time interval between compliance verification based on how critical the ESD protective equipment and materials are to their static control program.
All test methods in this document are based on current standards, standard test methods and standard practices currently published by the ESD Association. This technical report was prepared by the At that time the Gene Felder Desco Industries, Inc. Users of this document are responsible for selecting equipment that complies with applicable laws, regulatory codes and both external and internal policy.
Users are cautioned that this document cannot replace or supersede any requirements for personnel safety. Ground fault circuit interrupters GFCI and other safety protection should be considered wherever personnel might come into contact with electrical sources.
Electrical hazard reduction practices should be exercised and proper grounding instructions for equipment must be followed. DC Ohmmeter The meter should be capable of measuring a D.
The resistance between two electrodes should be less than 1. Hand-Held Electrode A stainless steel cylinder, 75 mm 3 inches or greater in length, and 25 mm 1 inch in diameter. A banana plug receptacle or screw connector is normally attached to one end of the cylinder. Foot Electrode A conductive metal plate, mm square 12 inches. Please note that some AC Outlet Analyzers may not be able to differentiate Ground and Neutral wire reversals, Hot and Neutral wire reversals and Hot and Ground wire reversals, or determine if the impedance to ground of the equipment-grounding conductor is within the company specification.

AC Circuit Tester Impedance Meter The meter should be capable of measuring the impedance of the equipment-grounding conductor from a receptacle power outlet used for establishing the AC tr53-10-06 ground to the neutral bond at the main esc equipment panel. The meter should also verify wiring orientation. The resistance of the insulative surface should be greater than 1.
Portable verification kits are commercially available and t53-01-06 consist of four components: If an Auxiliary ground is used, it should be electrically bonded to the AC equipment te53-01-06.
Reference the Test Equipment section in the beginning of this document. An AC Outlet Analyzer can be used to indicate the presence of the equipment-grounding conductor. Please note that some AC Outlet Analyzers may not be able to differentiate ground and neutral wire reversals, hot and neutral wire reversals and hot and ground wire reversals, or determine if the impedance to ground of the equipment-grounding conductor is within the company specification.
An AC Circuit Tester can be used esdd verify the integrity of the electrical circuit wiring as needed. Verify the following conditions: Neutral and equipment grounding conductor wires are present and not connected to each other at the receptacle outlet. Hot and neutral wires are not reversed. Hot and equipment-grounding conductors are not reversed.
Impedance of tr3-01-06 equipment-grounding conductor is not greater than 1. Operate the DC ohmmeter according to rr53-01-06 manufacturer’s instructions. Connect two test leads to the DC ohmmeter. Connect or place one test lead to the personnel groundable point and the other test lead to the ground reference. Verify the resistance and continue testing personnel groundable points.
Any AC outlet or directly connected equipment hard wire that fails the Receptacle Wiring Verification tests must be corrected by qualified personnel before further use or testing. Personnel Groundable Point Failures? Visually and mechanically confirm that all termination hardware and grounding wires are not inadvertently loose, broken, or disconnected.
Test the resistance of the personnel groundable point to common point ground. This periodic test procedure can also be used for the measurement of shelves, drawers and other ESD protective storage equipment surfaces. An integrated checker or meter, whether it is a single meter or a collection of instruments that are capable of measuring at least 1.
One electrode Two test leads of sufficient length DC Ohmmeter? Do not clean the ESD worksurface immediately prior to verification. Conductive items and AC-powered equipment having separate paths to the ground reference should remain connected to their grounds at the ESD worksurface being verified. Connect one end of the first test lead to the electrode, and the other end of the first test lead to the integrated checker or meter.
Connect one end of the second test lead also to the integrated checker or meter, and the other end of the second test lead to ground reference. Place the electrode in the center of the ESD worksurface and apply 10 volts. Eed for the integrated checker or meter to stabilize. If the indicated resistance is ess than 1. If the indicated resistance is equal to or greater than 1. Tests should include those ESD worksurface areas that are subject to wear or are visibly dirty.
Visually and mechanically confirm that all termination hardware and grounding wires are not inadvertently loose, broken or disconnected. Examine the ESD worksurface to ensure it is not soiled or worn, which could cause increased surface resistance. If soiled, clean the ESD worksurface with an approved cleaner. Ensure the surface is completely dry before retesting.
Periodic cleaning is recommended to maintain tr53-01-6 electrical function of all ESD worksurfaces. When checking ESD worksurface mats: Check the connection of the ground cord to the mat fastener. Check the connection of common point ground to the ground cord.
Check the connection of equipment ground to common point ground. Examine the electrode for dirt buildup. If using liquids to clean electrode, allow to the electrode to dry before retesting. With an integrated checker or meter, test the resistance of the ESD worksurface to the groundable point. The mechanical connection between the groundable point and the worksurface could become compromised by changes in humidity.
With a DC ohmmeter, test the resistance of the groundable point to common point ground. With a DC ohmmeter, test the resistance of the common point ground to equipment ground. Ensure the environmental ambient conditions have not dried out the worksurface material. Integrated checker or meter, whether it is a single meter or a collection of instruments that are capable of measuring from 5. Some integrated checkers require manual selection to wrist strap resistance test ranges. Hand-held electrode One test lead of sufficient tr53-011-06 Adjust the cuff if necessary eesd ensure a snug fit.
Attach the ground cord to the tr53-01-0 terminal – of the meter. Hold the hand-held electrode with the hand on t5r3-01-06 the wrist strap is being worn. Energize the meter using tr530-1-06 volts. Tr53-01–06 for the meter to stabilize. Measure the resistance of the cuff ed ground cord system.
When using a cloth cuff, it is recommended to periodically separate the buckle metal portion of the cuff from the skin measuring the continuity of the fabric and perform this test. Examine the cuff to ensure that it is correctly sized and adjusted snugly to the skin. Examine the cuff to ensure it is not soiled. Replace the cuff with a new cuff and repeat the procedure. Replace the ground cord with a new ground cord and repeat the procedure.
Some cuffs have a propensity to trap moisture underneath the cuff and esx be tr53-001-06 effective for people with dry skin. If skin lotions and gels are used, more frequent testing during the work shift may be required to ensure their continued effectiveness. Constant monitors are designed to provide ongoing testing of the wrist strap system. While a number of technologies are utilized, the goal tt53-01-06 consistent; electrical connections are tested between the ground point, ground cord, wrist strap and body while the wearer handles ESD sensitive items.
