- 300Lbs. Capacity. Distributed Weight.
- 1" Thick Top.
- Strong 16-gauge Cold Rolled Steel.
- Pass ESD Association Standards.
- 6” Height Adjustability on 2” increments.
- 2” Wide Glides to Level Workbench.
- 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.
Workbench WarrantyBenchPro™ has been producing the nation's strongest, longest lasting ergonomic workbenches since 1987. We are so sure our products will perform properly, we offer the following warranty: BenchPro™ benches, options and accessories are warranted to the original purchaser for 25 - years. This includes every component and every function. Exceptions: Workbenches used in multiple shift operations shall have the warranty prorated accordingly. Hydraulic bench lift - system components are warranted for ten - years. All lighting products are warranted for ten - years. For Service: Call BenchPro™ at 888-700-9888 or email info@benchpro.com. Customers only have the obligation to report the problem and BenchPro™ will take care of the rest. BenchPro™ will either refund the entire purchase price including freight (if by our freight carrier) and tax (if any) or replace the product or component that is defective at our discretion. Product Returns:
As we make all orders from base materials, and do not carry an inventory, we charge a "restocking fee" on unneeded and unwanted, yet ordered products. We also charge a restocking fee for products ordered but cancelled after the product is built. This is to cover our repackaging and handling, and remarketing. Customers pay the cost of freight both ways. Restocking fee schedule:
A. Kennedy, Roosevelt Series in standard sizes and colors will be charged 15%.
B. Dewey, Harding, Jefferson, Grant and Adams Series in standard sizes and colors will be charged 30% restocking fee.
C. Any bench in a custom size or color will be charged a 50% restocking fee, as we will have a difficult time reselling them without a large discount.
D. Custom design and non-catalogue items are non-returnable.
E. No product shall be returned after 60 days.
No return of defective product is ever required. (We ask for an electronic photo in cases where we have not seen the problem before).
Freight Damaged Product:
USA freight regulations make freight companies’ drivers responsible for checking shipments for damage when they pick up. Our customers are responsible for checking for damage when receiving and signing for a shipment. We state this on our acknowledgment and invoice in case customers are not aware of the procedure. Once the product is in your facility, we assume you mishandled the product.
Most carriers give us 5 days after delivery to notify them of damage, and will cover the cost of replacements and the freight. If you have a problem, call or write and we will notify the carrier, then replace the product at no charge to you.
