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.
Custom Testing and Consulting Projects
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.
