If an Auxiliary ground is used, it should be electrically bonded to the AC equipment ground. AC line powered resistance measuring devices may give erroneous results due to undefined ground paths.
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.
Packaging checks may depend on the composition of the packaging and its use. The objective of this periodic test procedure is to verify the resistance of the cart grounding system cart through grounded floor is within the minimum and maximum resistance allowed by the user’s specification.
He is well esv internationally as an outstanding ESD practitioner and as a major contributor to ESD technology for the past 25 years.

While a number of technologies are utilized, the goal remains consistent; electrical connections are tested between the ground point, ground cord, wrist strap and body while the wearer handles ESD sensitive items. Electrical hazard reduction practices should be exercised and proper grounding instructions for equipment must be followed. Personnel Groundable Point Failures? Compliance verification for the constant monitor should be performed to ensure that it is properly functioning within its operating parameters.
If the indicated resistance is less than 1. Examine the electrode for dirt buildup. Add to Alert PDF. Neither ESDA, nor its members, officers, employees or other representatives will be liable for damages arising out of or in connection with the use or misuse of ESDA standards or publications, even if advised of the possibility thereof.
Visually and mechanically confirm that all termination hardware and grounding wires are not inadvertently loose, broken, or disconnected. When holding the electrode, ensure you are not a path of lesser resistance to ground.
Some packaging may have static control properties that deteriorate more quickly with time and use and some packaging may be humidity dependent and may have limited shelf life. Thus, ESDA expressly disclaims any responsibility for damages arising from the use, application or reliance by others on the information contained in these standards or publications. If skin lotions and gels are used, more frequent testing during the work shift may be required to ensure their continued effectiveness.
Verify the resistance of the ESD floor surface to reference ground. Examine the garment cuff to ensure that it is correctly sized and adjusted snugly to the skin. Connect two test leads to the DC ohmmeter. 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 equipment ground to the neutral bond at the main service equipment panel.
Tests should include those ESD worksurface areas that are subject to wear or are visibly dirty. Energize the meter using 10 volts. Users of this document are responsible for selecting equipment that complies with applicable laws, regulatory codes and both external and internal policy.
Charge the test plate to a convenient voltage in excess of the initial test voltage for each polarity e.

Wait for the integrated checker or meter to stabilize. Tests should include those areas on the ESD chair that are subject to wear or are visibly dirty. The objective of this periodic test procedure is to verify the resistance of the ESD chair grounding system chair through grounded ESD floor is within the minimum and maximum resistance allowed by the user’s specification.
Already Subscribed to this document. Please first verify your email before subscribing to alerts. Check the connection of the mat fastener to the mat. With an integrated checker or meter, test the resistance of the ESD worksurface to the groundable point. The existence of such standards and publications shall not in any respect preclude any member or non-member of the Association from manufacturing or selling products not conforming to such standards and publications.
Subscribe to comments feed. Due to the wide variety of packaging materials in use, the users should develop their own compliance verification plan for packaging.
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.
Allow emitter points to dry before retesting. Check air filters for clogging with dust and dirt. The discharge time measurement begins when the test plate voltage has decayed to the initial test voltage e.

Do not clean the ESD worksurface immediately prior to verification. Constant monitors are designed to provide ongoing testing of the wrist strap system. If soiled, clean the ESD worksurface with an approved cleaner. Ensure the sleeves are separated from the body of the garment. If the ESD flooring surface resistance is high, clean the floor with an approved cleaner. Hand-held electrode Foot electrode Two test leads of sufficient length? You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.
Do not zero or charge the portable verification instrument in the presence of the ion field. Tests should include those areas on the cart that are subject to wear or are visibly dirty.
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. Other materials, such as ESD vinyl floor covering, may require less monitoring.
Measure the resistance of the ESD footwear system. Ensure the environmental ambient conditions have not dried out the worksurface material.
The resistance of the insulative surface should be greater than 1.
