The use of "i.e." does seem to limit to SnPb as the meaning is "that is
to say", explicitly, to be exact, to be precise.
The use of e.g., means "for example.

Subject: Re: [LF] High Lead Exemption

Annex item 7 does exempt such solder. It actually says "i.e. tin-lead
solder............" which to me does not limit the alloy to being just
tin-lead.

Subject: [LF] High Lead Exemption

Greetings

I apologize if this has been discussed earlier.  I have a question
regarding
the use of PbSn solders containing 85% or greater lead by weight.
1.      I understand that this class of solder is currently exempt by
the
RoHS Directive.
2.      I also understand that this exemption is ONLY for PbSn, and
other
high lead solder combinations are not exempt yet but the EU parliament
(sun
as PbSnAg, PbSb, PbSbSn, etc)
Please correct me if the above two statements are wrong.

I am interested in understanding the legal ramifications and
consequences of
using high Lead containing PbSn solders.  Since Pb is being
intentionally
added in solder form, will the product still be considered RoHS
compliant?
Can the products be marked/sold as being RoHS compliant?

Best Regards

Wasef
