Thanks to all who replied. Very good information. So can I conclude that Industrial Saws would have to comply with CISPR11 in Canada and probably in the US (or FCC part 15 or 18) and in Europe they are not exempt from the EMC Directive and would have to be compliant with EN55011 Class A and probably many other applicable EMC tests.
From what I have experienced it is very difficult to get a product to pass the Class A emissions requirements which has a high power inverter (frequency drive) driving a large motor. We are looking at a three phase line filter that has at least 60db of attenuation at 150Khz and can handle 30 amps. $$$$ Oh well, the cost of compliance. Thanks again.

All of the ICES standards can be downloaded for free on the Industry Canada web site<http://www.ic.gc.ca/eic/site/smt-gst.nsf/eng/h_sf06127.html>. Here’s the Scope of ICES-001: 1. Scope 1.1 This Interference-Causing Equipment Standard sets out the technical requirements relative to radiated noise emissions from ISM radio frequency generators. 1.2 Subject to subsections 1.2.2 and 1.2.3, Sections 3 to 7 apply to every ISM radio frequency generator manufactured in or imported into Canada except those manufactured or imported solely for export purposes. 1.2.1 A transition period ending December 1, 2006 is provided, within which compliance witheither ICES-001 Issue 3 or ICES-001 Issue 4 will be accepted. After the above date, only compliance with ICES-001 Issue 4 will be accepted. 1.2.2 Sections 3 to 7 do not apply to ISM radio frequency generators used: (a) solely for demonstration and exhibition purposes; or (b) as prototype units. 1.2.3 (1) Sections 3 to 7 do not apply to units or models of ISM radio frequency generators for which the Minister has granted the manufacturer, importer or owner a special permission. (2) The Minister may grant a special permission where: (a) the manufacturer, importer or owner has presented a written application giving: (i) the reasons for the request; (ii) an analysis based on sound engineering principles showing that the unit or model of ISM radio frequency generator will not pose a significant risk to radiocommunication; and, (iii) a guarantee of compliance with all the conditions the Minister may set in the special permission. (b) the Minister is satisfied that the unit or model will not pose a significant risk to radiocommunication. (3) The special permission is valid only if: a) the unit bears a label, either affixed or displayed electronically, stating that it is operating under special permission and setting out the conditions of that special permission; and, b) the unit complies with all conditions set out in the special permission. (4) The Minister may revoke or amend the special permission granted under subsection (2) at any time without prior notice.

Sounds like it would be FCC part 15 exempt providing the user stops operating the device upon a finding by the Commission or its representative that the device is causing harmful interference.

Most of these basic model saws have no high frequency devices and brushless AC motors so they do not generate EMI. However, the more expensive models have Inverters (Frequency Drives) to slow start/stop the motor and act as a break. We evaluated a saw from a company who says they do not require EMC testing on their saws even when they use the Inverter, as long as they follow the installation instructions from the inverter manufacturer (yea, I just about fell out of my chair). We tested one of these saws and failed CISPR 11 Class A Conducted Emissions by 50db (if was a prototype saw not on the market). How do these people sleep at night? So here is my question. Does the US and Canada require Emissions testing on Industrial Saws? Same question for Europe. I assume EN 55011 Class A is mandatory in Europe on such a devices. Please confirm (sanity check).
