Electrostatic discharge (ESD) flooring has become essential to many industrial facilities. It is essential to have proper ESD flooring to help protect sensitive electronics from damage caused by static electricity. Installing and maintaining ESD floors according to industry standards is critical for companies manufacturing or assembling electronics. This article will examine the key regulations and standards for ESD flooring in industrial settings.

ANSI/ESD and IEC standards

The primary standards for ESD flooring come from the ANSI ESD S20.20 and the IEC 61340-5-1 standards, which are considered the top sources. Both the American National Standards Institute (ANSI) and International Electrotechnical Commission (IEC) have teams of experts that have developed rigorous testing procedures and requirements for ESD flooring. These standards are designed to ensure ESD flooring is practical and effective.

The ANSI ESD S20.20 standard covers the development of ESD control programs. It provides requirements for selecting, installing and maintaining ESD flooring. It also shows requirements for transporting or handling electrical or electronic parts, assemblies and equipment that could be harmed by electrostatic discharges of 200 volts or more when charged with a current greater than 100 volts (HBM) or 100 volts (CDM). This standard also addresses isolation protection by capping the voltage applied to isolated wires at 35 volts or less.

The IEC 61340-5-1 standard focuses on electrostatics protection in electrical and electronic equipment. This standard provides the criteria for an ESD control program and IEC TR 61340-5-2[9] offers instructions for implementing this standard. This specification does not cover electrically triggered explosive devices, flammable liquids, gases and powders. Instead, this program aims to provide the operational and technological prerequisites for developing, executing and sustaining an ESD control program, as well as additional guidelines for evaluating and monitoring ESD flooring materials.

Essential requirements in these standards include testing floors for electrical resistance and charge dissipation. Approved ESD floors must have resistance between 1 million and 100 million ohms. They must also be able to dissipate a 5000V charge to less than 50 volts within 2 seconds. Regular testing per the standards ensures floors continue meeting requirements over time.

Compliance for safety and quality

Compliance with ESD flooring standards in industrial settings is about more than just meeting guidelines. Proper ESD floors improve safety and quality. Floors that meet resistance requirements prevent static electricity buildup. That helps reduce the risks of electrical shorts, sparks and shocks. Proper charge dissipation also prevents electrical damage to sensitive components handled on ESD flooring. This improves quality by reducing defects and failures related to electrostatic discharge.

Compliance with testing guidelines also ensures flooring continues working over time. Traffic, maintenance chemicals and other factors can degrade floors. Regular testing per ANSI/ESD and IEC standards will identify when floors no longer meet requirements. Facility managers can then take steps to restore or replace flooring. Keeping floors compliant improves safety and quality in the long run.


ESD flooring is necessary for any electronics manufacturing and assembly facility hoping to avoid safety hazards. Following industry standards for installation, maintenance and testing ensures ESD floors remain effective. With proper ESD flooring, companies can prevent safety risks and quality issues caused by electrostatic discharge. Keeping processes and flooring compliant provides confidence that sensitive electronics handled on ESD floors will avoid damaging effects from static electricity buildup or discharge.
