I must applaud the inclusion of the multiple certifications for Europe and North America. At least this will alleviate any possible delays based on testing.
I am curious as to what the "Canadian thing" was that had to be tested?
Kevin,
I'm not as confident as you seem to be that the testing done so far will
"alleviate any possible delays based on testing".
The FCC rules, Title 47, section 15.3 "Definitions", paragraph i, say:
"Class B digital device. A digital device that is marketed for use in a
residential environment, notwithstanding use in commercial, business
and industrial environments. Examples of such devices include, but
are not limited to, personal computers, calculators, and similar
electronic devices that are marketed for use by the general public."
But apparently, Class B testing has not been done, even though the
RPi is being marketed as a PC for use in residential environments.
There is another section, 15.32 "Test procedures for CPU boards
and computer power supplies", but it doesn't seem to have been
followed, from what we know. It refers to testing within an enclosure
with the cover removed.
Here is an update regarding CE mark compliance: http://www.electrocomponents.com/media/press-releases/2012/04/10th/
jbeale,
good find!
There are some odd things in that press release.
The first paragraph mentions that it is designed for children and IT enthusiasts
to develop programming skills, but the second paragraph mentions "industrial or
office environments". It seems unlikely to find either children or IT enthusiast
programming skill developers exclusively in industrial or office environments.
The second paragraph mentions a warning statement to ensure that customers
are fully aware that equipment used in a residential environment may be susceptible
to radio interference. I think the primary concern in residential environments is not
susceptibility of the equipment, but interference caused by the equipment,
which is not mentioned.
This susceptibility warning seems to imply that it's OK to market to residential
users with only a Class A certification, provided that a disclaimer is provided.
I'm not sure about the EC rules, but the FCC rules apparently don't allow this.
FCC OET Bulletin 62 (1993), which was pointed out to me on another thread,
says, bottom of page 8:
"If a digital device is sold or offered for sale to *any* (empasis in original) residential
users (including commercial or industrial companies that could employ the equipment
in a residential environment) then it is a Class B digital device regardless of its price
or application. Marketing through a general retail outlet or by mail order to the general
public with a simple disclaimer, such as "For Business Use Only," is not sufficient to
qualify for Class A."
Page 9 also says: "Portable computers, because they are designed to be used anywhere,
are considered Class B devices regardless of their price or restrictions placed on marketing."
The second paragraph of the press release mentions that the boards were tested to comply
with directive EN500081-2 (1993). But that is an emissions standard, not a susceptibility
standard. We were told that susceptibility to cats was tested, were we not? Hopefully the
boards were also tested to a more recent emissions standard than 1993.
Liz made a reply to comment on the "Testing Completed" R-Pi blog as shown below:

"Quite – a week in the testing chamber is *very* speedy, and we were only ever aiming for Class A; RS and Farnell were very clear that the board only has to be certified that far before the educational release. There’s been no “revision to easier limits”, I’m happy to say."
I'm not a compliance specialist so I don't know all the FCC Part 15 implications. It would be sad if the first run of boards was only available outside the US.
On the same page, Liz also made this comment:

Now I don't know if she's referring to CE "Class B" and/or FCC "Class B" but perhaps a redesigned consumer/residential use version will be available relatively soon*, anyway.
* well, what's a few more months, at this point?
"and we were only ever going for Class A" oh really??
what good is class A for a device designed for children
to use at home with a TV?
The 28 March front-page story "An update on CE compliance" says:
"On the basis of preliminary measurements, we expect emissions
from the uncased product to meet category A requirements comfortably
without modification, and possibly to meet the more stringent Category B
requirements which we had originally expected would require a
metalised case."
That sounds to me like they were in fact hoping to meet Category B,
with Category A as a fallback position.
