The Static Control System
A properly engineered static control flooring system consists of multiple integrated layers, each serving a specific function:
Testing Protocols
We perform testing per the following ANSI/ESD standards:
- ANSI/ESD STM7.1 — Floor Materials: Resistive Characterization of Materials
- ANSI/ESD S20.20 — ESD Association Standard for the Development of an ESD Control Program
- ASTM F150 — Standard Test Method for Electrical Resistance of Conductive and Static-Dissipative Resilient Flooring
All test results are documented and provided to you as part of our installation package, giving you certifiable records for compliance and audit purposes.
Complete Static Control Program
A truly effective static control program goes far beyond installing a conductive or static-dissipative floor. It requires a holistic, systems-level approach that addresses every potential source of electrostatic discharge in your facility. Without integrating all components into a unified program, gaps in protection leave sensitive electronics vulnerable to damage, data corruption, and costly downtime.
Our complete static control program encompasses the following critical elements:
- ESD Flooring — The foundation of any static control program. Conductive and static-dissipative flooring systems are engineered to drain electrostatic charges safely to ground, preventing charge accumulation on the walking surface.
- Grounding Systems — Copper grounding grids and straps are installed beneath the flooring and connected to building ground, providing a continuous, low-resistance path for charge dissipation. Without a properly designed grounding system, even the best ESD flooring cannot function as intended.
- Humidity Control — Relative humidity plays a significant role in static generation. Low humidity environments dramatically increase the rate at which static charges build on personnel and equipment. A comprehensive static control program monitors and maintains humidity levels within recommended ranges (typically 40–60% RH) to minimize charge generation.
- Personnel Grounding — People are the primary source of static generation in any facility. Heel straps, wrist straps, and ESD-safe footwear ensure that personnel remain grounded at all times, continuously dissipating any charge they generate through the flooring system to ground.
- ESD Testing — Regular resistance testing validates that all components of the system continue to perform within specification. Testing confirms that the flooring, grounding connections, and personnel grounding devices are functioning together as an integrated system.
- Certification — Formal certification documents the performance of your static control system against ANSI/ESD standards, providing auditable proof of ESD compliance for regulatory requirements, customer audits, and internal quality programs.
- Maintenance — Ongoing maintenance preserves system performance over time. This includes proper cleaning protocols that do not compromise the flooring's electrical properties, periodic inspection of grounding connections, and replacement of worn personnel grounding devices.
A systems-level approach is necessary because static control is only as strong as its weakest link. A conductive floor without proper grounding cannot dissipate charges. Grounded flooring without personnel grounding allows body voltage to reach damaging levels before a discharge event. Testing without documentation leaves your facility unable to demonstrate ESD compliance during audits. Each component reinforces the others, and only when all elements are integrated into a cohesive static control program can you achieve reliable, verifiable protection for sensitive electronics.
Testing & Documentation
Thorough testing and documentation are the backbone of any credible static control program. Without verified, documented test results, there is no way to confirm that your system meets ANSI/ESD standards or to demonstrate ESD compliance to auditors, customers, or regulatory bodies. Our testing protocols cover every critical measurement required to validate system performance.
Point-to-Point Resistance Testing
Point-to-point resistance testing measures the electrical resistance between two points on the floor surface. This test verifies that the flooring provides uniform conductivity across the entire installation area. Inconsistent resistance readings can indicate installation defects, coating thickness variations, or grounding discontinuities. Per ANSI/ESD STM7.1, measurements are taken at multiple locations using a standardized electrode configuration to ensure the floor meets the required resistance range for either conductive (<1.0 x 106 ohms) or static-dissipative (1.0 x 106 to 1.0 x 109 ohms) classification.
Point-to-Ground Resistance Testing
Point-to-ground resistance testing measures the total resistance from any point on the floor surface through the coating system, conductive primer, copper grounding grid, and ground connection to the building electrical ground. This end-to-end measurement confirms that the complete grounding path is intact and within specification. High point-to-ground readings may indicate a compromised grounding connection, damaged conductive primer, or a break in the copper tape grid.
Body Voltage Generation Testing
Body voltage generation testing measures the electrostatic charge that accumulates on a person walking across the floor. Using a body voltage meter, a test subject walks a defined pattern on the flooring while voltage levels are continuously monitored. This test directly measures the real-world effectiveness of the static control system in preventing dangerous charge buildup on personnel. Effective ESD flooring combined with proper footwear should limit body voltage generation to below 100 volts.
Walking Test per ANSI/ESD STM97.2
The walking test per ANSI/ESD STM97.2 is the definitive performance test for ESD flooring systems. This standardized test protocol specifies the exact procedure for measuring body voltage generation on a person walking on the floor while wearing standardized ESD footwear. The test simulates real-world conditions and provides a repeatable, comparable measurement of system performance. Results from this test are the primary metric used to certify that a static control flooring system meets the requirements of ANSI/ESD S20.20.

Frequently Asked Questions
What is a static control program?
A static control program is a comprehensive, integrated system designed to prevent electrostatic discharge (ESD) damage in environments with sensitive electronic equipment. It encompasses ESD flooring, grounding systems, humidity control, personnel grounding devices, regular resistance testing, formal certification, and ongoing maintenance. The goal is to control static charge generation and ensure safe dissipation through a verified path to ground, meeting the requirements of standards such as ANSI/ESD S20.20. A properly implemented static control program protects equipment, reduces failures, and provides documented proof of ESD compliance.
How often should ESD flooring be tested?
ESD flooring should be tested immediately after installation for initial certification, and then re-tested at least annually with a full point-to-point and point-to-ground resistance testing protocol. Semi-annual spot checks are recommended for high-traffic areas and zones near critical equipment. Additional testing should be performed after any ESD-related incidents, chemical spills, physical damage to the floor, or modifications to the flooring or grounding system. Consistent, documented ESD testing ensures ongoing compliance and early detection of system degradation.
What grounding system is used under ESD flooring?
The grounding system used under ESD flooring consists of a copper tape grid installed directly on the prepared substrate before the conductive primer and topcoat are applied. The copper tape is laid in a grid pattern—typically on 6-foot centers—to ensure uniform charge dissipation across the entire floor area. The grid is then connected to the building's electrical ground using copper ground straps at designated bonding points. This grounding system provides a continuous, low-resistance path from every point on the floor surface to earth ground, which is essential for the flooring to effectively dissipate static charges.
What is the difference between conductive and static-dissipative flooring?
The difference between conductive and static-dissipative flooring lies in their electrical resistance. Conductive flooring has a resistance of less than 1.0 x 106 ohms (1 megohm), allowing charges to dissipate very rapidly. Static-dissipative flooring has a resistance between 1.0 x 106 and 1.0 x 109 ohms, which dissipates charges more slowly but still effectively. Conductive floors are typically used in environments with extremely sensitive components, while static-dissipative floors are appropriate for most data center and electronics manufacturing applications. Both types require a proper grounding system to function and must meet the resistance testing requirements of applicable ANSI/ESD standards.
Do you provide certification documentation?
