Compliance Verification Plan
“A Compliance Verification Plan shall be established to ensure the Organization’s fulfillment of the technical requirements of the ESD Control Program Plan. Process monitoring (measurements) shall be conducted in accordance with a Compliance Verification Plan that identifies the technical requirements to be verified, the measurement limits and the frequency at which those verifications shall occur. The Compliance Verification Plan shall document the test methods and equipment used for process monitoring and measurements. If the test methods used by the Organization differ from any of the standards referenced in the document, then there must be a tailoring statement that is documented as part of the ESD Control Program Plan. Compliance verification records shall be established and maintained to provide evidence of conformity to the technical requirements.
The test equipment selected shall be capable of making the measurements defined in the Compliance Verification Plan.” (ANSI/ESD S20.20 section 7.3)

Operation
Compliance Verification Test Procedure Guideline
The ESD Association lists test procedures and troubleshooting tips in Compliance Verification ESD TR53.
NOTE: The test kit can be used to measure RTG and RTT of shelves, garments, floor and cart worksurfaces using test procedures similar to worksurfaces and foot grounders.
Measure Worksurface Resistance to Ground (RTG)
- Do not clean the surface.
- Remove all ESD sensitive items from the surface and items that might interfere with the test.
- Connect one lead banana plug to ground.
- Use one 5 pound electrode on the other test lead and place it at the center of the surface.
- Set the Test Voltage Button to AUTO. Press and hold the the TEST button until the measurement is displayed (see Figure 3).
- Perform additional measurements by placing the electrode on the most commonly used or worn areas.
CAUTION: If there is a current limiting resistor in the worksurface and the worksurface resistance is lower, the measurement will primarily be the resistance of the resistor. It is recommended to measure RTT particularly if the material color is black.
Recommended Frequency of Periodic Compliance Verification of Installed Products
The ESD Association lists test procedures and troubleshooting tips in Compliance Verification ESD TR53.
NOTE: “The frequency of periodic testing is normally specified in corporate operating procedures. …The frequency of testing is driven by the amount of risk exposure that can occur between tests. For example, what is the quantity of product handled between test periods?” (See ESD Handbook ESD TR20.20)The ESD Association lists test procedures and troubleshooting tips in Compliance Verification ESD TR53.
A Guide for Periodic Testing
TR20.20 section 5.3.1.13 Periodic Tests)
- Worksurface, Carts, Shelves – at least quarterly (see ESD TR20.20 section 5.3.1.13 Periodic Tests)
- Footwear – “Incoming inspection on a lot sampling basis should be performed for all static control footwear.” (see ESD TR20.20 section 5.3.3.4 Testing)
- Floor – “In some cases, a simple electrical resistance test with a megohmmeter may suffice. In others, a static charge generation test may be required. The frequency of testing is also a consideration. Some materials, such as floor finishes, may require more frequent testing because of their lack of permanency.” (see ESD TR20.20 section 5.3.4.15.1.4)
- Seating – “The recommended electrical resistance range for seating is less than 10E9 ohms as tested in accordance with ANSI/ESD STM 12.1. This value should be during acceptance testing, installation and periodically thereafter.” (see ESD TR20.20 section 5.3.5.3 Testing
- Garments – “ESD TR53 describes periodic verification test methods and troubleshooting for garments. The sleeve to sleeve resistance test should be made to ensure proper resistance range through the entire garment. Alternately, the garment while worn can be tested using a wrist strap tester.” (ESD Handbook ESD TR20.20-2008 section 5.3.13.3.1.7 Periodic Verification Testing)
Maintenance
The area surrounding the cable jacks at the top end of the meter should be wiped with a clean cloth moistened with alcohol to remove skin oils that will accumulate and affect the accuracy at high resistances. The frequency of cleaning will depend on usage; once a month would be a good starting point.
Per ANSI/ESD S4.1 “Clean the electrodes with a minimum 70% isopropanol-water solution.” Make sure conductive pads are dry prior to use.
The Analog Surface Resistance Meter requires little maintenance, and there are no user serviceable parts. If your unit requires service beyond cleaning the electrodes or replacing the batteries, please contact StaticWorx Customer Service on 617-923-2000.

Analog Surface Resistance Test KitFrequently Asked Questions
What is the purpose of the Analog Surface Resistance Test Kit?
This portable, battery-powered meter measures surface-to-ground (RTG) and point-to-point (RTT) resistance, helping ensure that ESD-protected areas, floors, carts, garments, and other surfaces meet ANSI/ESD S20.20 standards.
When should ESD surfaces be tested?
- Before installation to qualify for inclusion in an ESD control plan
- During initial installation
- Periodically, as part of ongoing compliance verification testing per ANSI/ESD S20.20 and TR53
What does the kit include?
- Analog Surface Resistance Meter
- 9V Alkaline Battery
- 2 Shielded Test Leads
- 2 Five-Pound Electrodes
- Plastic Carrying Case
- Certificate of Calibration
How does the meter work?
The meter displays surface resistance readings from 1 x 10³ to 1 x 10¹³ ohms. It automatically selects the test voltage (10V or 100V) and uses color-coded LEDs to provide quick resistance indicators. Measurement is done by placing the electrode on the surface and pressing the test button.
How often should surfaces be tested?
- Worksurfaces, carts, and shelves: at least quarterly
- Footwear: incoming inspection on a sampling basis
- Flooring: varies based on material and usage; some finishes require more frequent testing
- Seating: resistance should be less than 10⁹ ohms during acceptance and periodically thereafter
- Garments: periodic verification per ESD TR53
How should the meter be maintained?
- Clean electrodes monthly with 70% isopropanol-water solution to remove oils
- Replace the 9V battery as needed; low battery LED will indicate when power is low
- No other user-serviceable parts; contact StaticWorx Customer Service if repairs are needed
