We use copier vellum. It's insulative to ~4KV. It does tear, but we get it in rolls (1m X 50M) and cut off a new section when the old one get torn up.
"I" wouldn't think in the range of 1mm +/-0.5mm would be too critical provided that any metallic surface or part of the EUT doesn't contact the horizontal coupling plate. However; :-) We've had (over-eager) ISO 17025 inspectors use a micrometer to verify that our material meets the thickness specifications. Regards David Spencer From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Monday, April 28, 2008 11:47 AM To: [email protected] Subject: ESD test - insulating material Dear All, Clause 8.1 of EN 61000-4-2 calls for table-top equipment to be placed on an insulating support 0.5 mm thick. Can anybody recommend a suitable material (and UK based supplier if possible)? It would be nice if it was reasonably immune to tearing. I've looked in RS and Farnell and their plastics materials all seem to be too thick. Does this matter?
