Testing Services

ETS provides electrostatic testing services through our independent ESD Material Testing Laboratory. This convenient service enables companies that are not ready to commit to equipping their own ESD test laboratories to evaluate or qualify ESD control products. Auditing and consulting services are also available to assist with material analysis, product development, and other related parameters.

ETS has been involved in developing many of the electrostatic standards in use today, and we have one of the largest independent electrostatic test laboratory in the U.S. Our testing laboratory provides expert analysis for the development, qualification, quality control, and certification of materials and products. We address areas of concern such as:

  • Ensuring comprehensive material characterization;
  • Simulating ESD events onto microelectronics to ensure component ability, capability and reliability;
  • Providing in-depth knowledge of industry standards, test methodologies, and analysis; and
  • Consulting on troubleshooting, failure analyses, and corrective actions.

ESD Material Testing:

ETS evaluates the electrostatic characteristics of materials and products using resistance/resistivity, static decay, static shielding and triboelectric (or corona charging) test methods.  Tests are performed at ambient or controlled-environment conditions, and ETS’ facilities include microprocessor-controlled humidity chambers and a controlled environment room.  ETS tests a broad range of products across various industries.


Static Decay measures the ability of a material to dissipate an applied charge when grounded. Samples are electrically charged to ±5kV, and we measure the time required for the charge to bleed off to either the 10% or 1% level. Variations of this procedure are used to evaluate many types of material and finished products, including:

  • Completed parts or assemblies;
  • Packaging materials;
  • Woven and non-woven materials;
  • Containers;
  • Labels and films;
  • Garments and gloves;
  • Foams;
  • Bags;
  • Flooring; and
  • Work surfaces.

Static Dissipation

SAE J1645 for automotive fuel systems is an example of a specification that uses this measurement technique. We can also measure the time a material retains an applied charge (commonly referred to as charge retention).


ETS can perform testing using virtually any standard or test method. We can deliver results in accordance with, but not limited to, the following commercial and military standards:

  • Federal Test Method Standard (FTM) 101C, Method 4046
  • Mil PRF 81705F
  • Mil C 83429B
  • Method 5931
  • ESDA
  • IEC
  • NFPA
  • INDA
  • CECC
  • BS (British Standard) 7506
  • SAE


Surface Resistance and Surface Resistivity are the most common tests for measuring the surface of p, liquids, and powders. These tests are intended to predict the ability to bleed off or retain static charge using industry standard or custom test fixtures. Resistivity (when appropriate) is calculated from the measured resistance using the dimensions of the electrodes and/or test sample.

Volume Resistance and Volume Resistivity are the most common tests for measuring through the thickness of p, liquids, powders, and finished product. These tests are also intended to predict the ability to bleed off or retain static charge using industry standard or custom test fixtures. Resistivity (when appropriate) is calculated from the measured resistance using the dimensions of the electrodes and/or test sample plus the thickness of the sample.


ETS can perform testing using virtually any standard or test method, although most testing is performed in accordance with the following commercial and military standards:

  • ESD Association (ANSI/ESDA STM 4.1, 11.11, 11.12, 11.13),
  • ASTM (D-257, D-991 and F-150),
  • NFPA (99, and 77)
  • Mil-PRF 81705F
  • IEC
  • EN1149
  • BS7506


Triboelectric Charge Generation evaluates the ability of material or objects to generate charge when rubbed against or separated from another material, or from itself. The variables that can affect these measurements include material relationship on the triboelectric scale, environmental, mechanical, electrical, and data interpretation. ETS obtains data using nanocoulombmeters, charge plate monitors, and high-speed oscilloscopes.


ESDA Adv 11.2 describes several test methods, including the inclined plane test that measures the charge buildup on quartz and Teflon® cylinders rolled down a 12” (305mm) material sample mounted on a grounded surface inclined at 15°.

  • Compliance Tests: 6 samples using 6 of each cylinder type
  • Indication Tests: 6 samples using 3 of each cylinder type

USPS-T-3204 Sec. 3.1.8 Electrostatic (Static Charge) testing of mailer film: Standard defining the maximum charge developed when mailer film wrapped around a standard 8 ½ x 11” tablet is separated from another tablet.

Label Testing: Measures the maximum voltage on labels when separated from their liners.


Static Shielding per ESD S11.31 (Energy) – This test measures the energy inside a static shielding bag. A 1kV Human Body Model (HBM) discharge is applied to the outside surface of a bag clamped between discharge, capacitive sensor, and ground electrodes, and the ESD pulse that penetrates the bag is measured.


The ETS Test Suite Manager program generates a complete report of the peak current and energy measured inside the bag in accordance with ESDA STM 11.31.

  • Compliance Tests: 12 samples (6 at 12% & 6 at 50% RH)

Individual Specimens (Tested at 12% & 50% RH)

  • Indication Tests: (Tested at one R.H. level)

Static Shielding per EIA-541 -1988 (Voltage Differential) – This test measures the voltage differential between the induced charge on the upper and lower electrodes of a capacitive probe. Testing is performed in accordance with the following:

  • ESD S11.31 (Energy)
  • EIA 541-1988 (Voltage Differential)

ESD Microelectronics Testing:

ETS’ Microelectronics Test Lab provides semiconductor and electronics design firms worldwide with testing and evaluation support to facilitate new product introduction and reliability evaluation. We actively serve a range of semiconductor and electronics companies worldwide, and the fact that ETS designs and builds the equipment used in that testing gives us an extensive base of knowledge for this analysis.


Susceptibility Testing of Devices, Sub-Assemblies and Products – Evaluates the electrostatic discharge (ESD) susceptibility of electronic components, systems, and non-electronic devices using either Human Body Model (HBM), Machine Model (MM), Human Metal Model (HMM) or Charged Device Model (CDM) discharge networks.

ESD Simulation (Components): Performed using an HBM at voltages from <±5 to 8,000 Volts (V) or an MM up to ±1,000V. Single or multiple discharges are applied to defined pin combinations in stepped voltage increments until deterioration or failure occurs. CDM testing is also available up to 1,000V.

ESD Simulation (Systems): ESD simulators determine likely failure points and voltage susceptibility levels of assemblies and complete systems. Simulators can be configured with either HBM or HMM networks up to ±30kV and MM or CDM networks up to ±6kV.


ESD simulators can be configured with the following discharge networks to apply ESD pulses to the Device Under Test (DUT):

  • Human Body Model (HBM) per Mil Std 883 and ANSI/ESDA/JEDEC JS001;
  • Machine Model (MM) per ANSI/ESDA S5.2;
  • Human Metal Model (HMM) per IEC61000-4-2; or
  • IEEE, JEDEC, EIA plus other similar industry, military and international standards.


Charge and access cards can be charged by cardholder movement. When swiped or inserted, the card and/or the person using it can discharge to the device to which it is being inserted. The resulting discharge has the potential to disrupt or damage the device.


ETS has a comprehensive testing protocol to evaluate the ESD characteristics of these cards. Measurements include the following:

  • Card resistance characteristics;
  • Ability to become charged when rubbed with different materials and by the movement of the card holder;
  • Application of voltages up to 10,000V on the card and measuring discharge current (Ip) into a test target, followed by calculation of the resulting discharge energy (E) using the ETS Test Suite Manager Energy Calculation Program; and
  • Performing threshold tests using an actual device.

Custom Testing and Consulting Projects:

ETS’ custom testing is designed for products that cannot be evaluated using standard test methods. These tests generally reference the guidelines of one or more standards with appropriate modifications. Please note that specific applications may require ETS to develop new test protocol(s), including the design of a custom apparatus.


Used to evaluate static charge buildup on personnel either walking across a floor or performing a defined step-and-scuff sequence on flooring samples.  This test evaluates footwear and/or flooring, and can be expanded to include static charge buildup of seating, carts, and other mobile furnishings as they are moved about.


Personnel or objects stand (or are placed) on an insulated surface and are charged up to 10,000V. The subject or object is then discharged to a S____ U____ T____ (SUT) or to ground, and the discharge current (Ip) and energy (E) measured.


Applies a Human Body Model (HBM) discharge pulse (V) to the material or object under test and the current (I) measured. The ”Dynamic Resistance” is then calculated using the formula R=V/I. This resistance may be lower than the standard DC resistance measurement and may be a better indicator of the ability of a material or an object to dissipate a static discharge.

ETS evaluates non-electronic material or products that can be adversely affected by ESD using an HBM or custom discharge network with capacitance up to 0.5μf and resistance down to 0 Ohms. Voltage/capacitance limits apply.
