Hi Mike,
Point well taken. However, from a CEMs perspective, I was referring to stating the corresponding exemption on the IPC material declaration sheets (listed under the RoHS Material Composition Declaration field), that will accompany the RoHS 5 (for a lack of better term) assemblies to the customer. If anyone thinks this is incorrect, I'll be glad to know the correct way.

Sincerely,

Subject:        Re: [LF] [TN] RoHS 5 and RoHS 6

Folks,

Let me be abundantly clear: there is NO SUCH THING as "RoHS 5". I recommend
that you drop it from your lexicon and never speak of it again. ;o)

Your products, if they are within the scope of RoHS (EU), must comply with
the maximum concentration values in homogeneous materials for all six
classes of restricted substances, taking in to account applicable
exemptions.

One of these exemptions is for "lead in solder for servers, storage and
storage array systems", and "network infrastructure equipment for switching,
signalling, transmission as well as network management for
telecommunication". Read the Annex, paragraph 7, lines 2 and 3 and you will
see this exemption.

When people speak (sometimes lovingly ;o) of "RoHS 5", they are referring to
this specific exemption. It ONLY exempts lead used in solder; for instance,
on PCB-mounted components, the PCB itself, and the solder used to join them,
or wires to connectors. OTHER USES OF LEAD WHICH ARE NOT EXPLICITLY EXEMPTED
BY THIS OR OTHER GRANTED EXEMPTIONS ARE NOT EXEMPT! Thus your products may
not, for instance, contain lead in plastics (commonly used in flat cables,
etc.). And you'd better check for this if you haven't yet...

So "RoHS 5" is a shorthand misnomer. It is misleading; one admittedly very
significant exemption for lead does not exempt ALL uses of lead in
electronics. If you cannot tell yet, I really dislike this term because it
is dangerously imprecise.

Also, Mr. Kane's statement below that you have to state anything is a bit
misleading. To restate Chris' comments a bit differently, this is a "self
declaration" process. You don't have to "state" anything; you don't have to
"declare" anything; you don't need a mark of any kind anywhere including a
"CE" mark in order to comply with EU RoHS. You simply have to explain, when
asked by an enforcement authority or maybe a customer, why your products are
the way they are (in scope/out of scope/able to take xyz exemption/etc.)...
convincingly... with data...

RoHS 5 is a termed coined by industry. It is not in the legislation.
RoHS 5 is understood to mean you are claiming an exemption which permits
the continued use of lead. There is no provision you need to declare you
have used an exemption. However you would need to declare such on any d
of c you might be asked for and you are best advised to internally
document your decision for claiming the exemption for when the rohs
police with their xrf guns come a knocking...........

Regards,

Chris

Hi Joel,
The EU legislation limits the use of 6 hazardous chemicals (Lead,
Cadmium, Mercury, Hex Chromium, PBBs and PBDEs). RoHS 6 compliant means
that all these 6 substances are below the permissible level in the
assembly. RoHS 5 means that 5, out of the 6 substances are below the
permissible level, and the 6th substance is above the permissible level,
but is covered by a RoHS exemption (thereby making the assembly RoHS
compliant). Usually lead is above the permissible level in RoHS 5
assemblies as there are lead solder exemptions for specific
applications.

If your assembly is RoHS 6, you need not declare a class, but if its
RoHS 5, you must state that it is RoHS 5 and then state the exemption
class that is applied to the product.

Can anyone explain these two classes of RoHS and do you have to claim a
class or just declare that you product is RoHS compliant
