Cortland, the Directives require that products be compliant with the essential requirements. Compliance with voluntary harmonized standards provides for the presumption of compliance, but application of the standards is not mandatory. Optionally, one may apply any solution to demonstrate compliance then construct a TCF that documents the product construction and the solutions applied to ensure compliance. The file is submitted to a Notified Body for an opinion of compliance with the essential requirements. This TCF method does not provide for an automatic presumption of compliance, so the file must be available for inspection by the national authorities. The TCF method is used by some companies where the product, such as a computer, has many options that would be difficult and time consuming to test all combinations.
Richard Woods ---------- From: Courtland Thomas [SMTP:[email protected]] Sent: Monday, January 08, 2001 1:09 PM To: emcpost Subject: TCF's Hello group, I would like to know the intent of TCF's for CE. There are numerous standards such as Radiated Emissions, Conducted Emissions, ESD, Radiated Immunity, Fast Transients, Surge, etc..., that apply. What actually is the intent of the TCF? Is it to allow the manufacturer to select only certain standards in lieu of testing to all the standards?
