New measurement device for ESD Lab Coats / Smock
Testing the electric conductivity of your lab coats laboriously and space consuming? Eurostatgroup offers you a solution!This newsletter informs you about the new way of measurement of Lab Coats. Secure, ergonomically adjustable to any operator, robust, extreme long life time, reliable and most of all work friendly to use.?
Why should you measure the electric conductivity of ESD garments? The ESD garment protects electrostatic sensitive devices from field induction effects (non-contact charging of objects) caused by the personal clothing of human operators. The ESD garment is constructed in a Faraday cage style which will prevent the electric field emanating from a person’s clothing to charge an object.?As the washing process has an impact on the electrical conductivity over time, it is very important to periodically check the electrical conductivity for continued protection of your ESD sensitive devices.
The measurement of ESD clothing takes some effort, due to requirement to spread garments out flat on a table in order to place the test probes in a stable manner.?Large space is required to?arrange a measurement and time consuming.?
Rental and washing companies take care of?measurement of your ESD clothing. But this is done on relatively small batches due to the time consuming process, which results in extra costs. We noticed that during testing using conventional probes, the probe stability on the garment is a critical factor which directly influences reproducibility of results. This may lead to non-compliancy with respect to ANSI / ESD S20.20 and/ or IEC61340-5-1.?
A new test device was developed by Total ESD Solutions. A unique measuring device which will help you to arrange a fast,?reliable and above all, reproducible test conform the ANSI/ ESD STM2.1 and/ or IEC61340-4-9 test method description.
Test points of the garment (typically cuffs and/ or trouser legs) are put in two electrically isolated clamps. The clamps are connected to a high impedance meter, just like with the probe method. The test involves a point to point electric resistance test. Garments are not damaged in any way by the clamping system, even after hundreds of clamping actions.

Engaging and disengaging of the clamp system is done without any effort by the operator and the clamping force is adjustable to the garment type. As the height, width and depth of the clamping frame can be adjusted, it can be made ergonomically fit for any operator.?
The required space of one clamping system is less than one sixth of the space needed for a conventional method using probes on a large table. By default intended for table top use, configuration options of the garment test clamp system allow for a floor standing option, which would not require a table at all.?
No need to spread out garments on a table anymore, you can leave them in their transport crate. Less handling and more garments can be tested per batch. Very fast while remaining accurate and consistent.?
Additional selectable options include a position adjustable tray for holding the high impedance meter (adjustable for ergonomic purposes)?and a bar code scanner/ RFID tag reader (for registering the test result with the garment).
Future developments will allow for auto start of the electrical conductivity test (using a Prostat High impedance meter), which can be triggered by the scanning of the bar code/ or reading the RFID tag, after the garment is clamped. The test result is automatically stored with the bar code for future reference (garment conductivity over life time) and reporting to customer.
