What is included with an ESD system?
Special Top Features:
1. We Use LisStat™ ESD Laminate: Uses a design which controls the static dissipation rate to meet all ANSI/BIFMA and Federal GSA standards. This laminate carry the static charge across a layer of carbon which is buried just below the surface color layer.
Some of our competitors still use brands of ESD laminate which are made conductive by dipping conventional laminate sheets into a chemical bath, then dry the sheet.
These sheets come from the laminate dipper with a label which, to paraphrase it, reads Do not clean with any products containing water, ammonia, chlorine, or soap. We have replaced hundreds of competitors tops which have lost their ESD properties over time, even though they followed all the manufacturer instructions.
2. We use ESD laminate on the top and all four edges. As surprising as it sounds most other companies either use a non-dissipative rubber strip or use nonconductive laminate on the edges. If you already have a competitors ESD bench, you can spot this by checking to see if the laminate looks identical in color, thickness and texture. If it looks different, check the surface resistivity. It won't be the same.
3. Aluminum underside: We are the only bench manufacturer to use an aluminum sheet to seal the underside of our tops and to assure conductivity. While other makers either leave the core particleboard uncovered on the bottom, paint the bottom or apply a brown paper sheet, we use the only material which completely seals out moisture, and which is 100% conductive. This is important too, as this moisture is the only reason tops warp, and leaving a nonconductive bottom sheet can cause problems in sensitive work areas.
4. Multiple grounding systems: While other brands of benches tout a very special bolt used to ground the surface of the laminate to their grounding system wires, we have eliminated this bolt (And the wires). Because all BenchPro™ bench tops are designed with a full 180 degree laminate radius on the front edge, and because the front laminate wraps under the top of the frame, we simply placed the frame where the fastening screws go through the laminate. This directs the static charge directly into the frame, which is in turn grounded by two conductors we provide for earth grounding purposes. All ESD shelves have the same grounding system.
The two front legs have banana jacks on their front edges to accept wrist strap connectors. The back of the frame has two mounting lugs to attach the two grounding wires which are included with the system. You will find this double system in evidence on every ESD bench and accessory we make.
BenchPro™ ESD work benches are not connected electrically to the floor. We use insulated floor glides so static charges will pass only through the grounding system provided, and so inadvertent charges on the floor can not pass up to the work surface and operator.
The unique characteristics of LisStat™ Static Dissipative Laminate make it ideally suited for a variety of sensitive electronic production applications.
LisStat™ Static Dissipative Laminate Sheets are designed for permanent lamination to work station surfaces.
LisStat™ meets and surpasses all standards for electrical dissipation as they apply to static control, even at low humidity levels. These standards include ANSI/BIFMA, ESDI, GSA and many others.
LisStat™ Static Dissipative Laminate Sheets are designed for permanent lamination to work station surfaces.
All BenchPro™ ESD benches are only available with ergonomic contoured front edges. This way, the ESD laminate conducts the static charges all the way to the steel frame. The steel frame has two wrist strap jacks mounted on the top of the two front legs for convenience. BenchPro™ also provides one grounding wire to take the static from the frame to either an adjoining bench or to ground.
To guarantee a static clear work area, all BenchPro™ ESD bench top have their edges laminated with the same static control laminates as used on the top, while the underside of the tops have a laminated solid aluminum sheet.

- Standard: ESD laminate top with grounded frame under standard (insulating) powder coat.
- Upgrade: Entire frame, legs, and structure coated with static-dissipative ESD paint (10⁶–<10⁹ Ω to ground).
- Spec: Fits the ANSI/ESD S4.1 worksurface guideline of ≥1×10⁶ to <1×10⁹ Ω and the ANSI/ESD S20.20 requirement of <1×10⁹ Ω to ground.
- Result: Top, frame, and legs all function as one ESD-controlled workstation, not just the worksurface.
Electrostatic Discharge (ESD) Control Testing
Electrostatic discharge (ESD) control testing was performed in accordance with ANSI/ESD S20.20-2021, using the ANSI/ESD STM4.1-2017 test method for worksurfaces.
The objective of this testing is to verify that the ESD paint and steel structure meet the required Resistance to Ground (RtG) limits so the bench is suitable for use in an Electrostatic Protected Area (EPA).
Product Under Test:
ESD workbench with ESD-finished steel structure.
Scope and Approach
Testing was carried out on the ESD workbench at representative contact points along the painted structure, following the discharge path from the ESD paint through the frame to the grounding connection point. This validates that the bench provides a controlled, compliant path to ground across the structure for use in EPA environments.Tools Used
To perform the resistance measurements, we used a DESCO LCD Megohmmeter (Item A50070), a meter designed for testing ESD worksurfaces and grounding paths.
Measurements were taken by connecting one terminal of the meter to the ground reference point and placing the test electrode on each selected point of the painted structure.
Note: According to ANSI/ESD S20.20-2021, the maximum allowable Resistance to Ground (RtG) for ESD worksurfaces in an EPA is < 1.0 × 10⁹ ohms.
PROCESS & RESULTS: Work Surfaces
Measurements were taken from the main worksurface and shelving to the ground point. Both surfaces showed excellent conductivity.
| Test Location | Result (Ohms) | Limit | Status |
|---|---|---|---|
| Worksurface Top | 4.4 × 10⁸ | < 1×10⁹ | PASS |
| Top Shelf | 3.3 × 10⁶ | < 1×10⁹ | PASS |
PROCESS & RESULTS: Accessories
Vertical accessories and holders were tested to ensure the paint provides a path to ground throughout the structure.
| Test Location | Result (Ohms) | Limit | Status |
|---|---|---|---|
| Pegboard | 1.9 × 10⁵ | < 1×10⁹ | PASS |
| Roll Holder | 2.0 × 10⁷ | < 1×10⁹ | PASS |
| Bin Box Rail | 1.4 × 10⁶ | < 1×10⁹ | PASS |
| MHLK (LCD Monitor + Keyboard Holder) | 3.7 × 10⁷ | < 1×10⁹ | PASS |
PROCESS & RESULTS: Storage & Ground
Drawers and the main frame were tested. All components passed, ensuring a safe discharge path for the operator and equipment.
| Test Location | Result (Ohms) | Limit | Status |
|---|---|---|---|
| Drawer 1 | 1.2 × 10⁵ | < 1×10⁹ | PASS |
| Drawer 2 | 4.0 × 10⁵ | < 1×10⁹ | PASS |
| Frame | 2.1 × 10⁷ | < 1×10⁹ | PASS |
| Power Strip | 2.6 × 10⁷ | < 1×10⁹ | PASS |
Conclusion
Testing demonstrates that the ESD workbench is in full compliance with the Resistance to Ground (RtG) requirements for structures and surfaces that come into contact with static-sensitive items.
- Final Declaration:The product meets the ANSI/ESD S20.20-2021 acceptance limit of < 1.0 × 10⁹ ohms RtG.
- Suitability: The ESD paint and finished steel structure are suitable for use in Electrostatic Protected Areas (EPAs) and provide a compliant foundation for an effective ESD control program.
