In the US, yes, in Europe different. Many make official agreements, despite
it's not a must. The MIL industry is not even mentioned.
Many thoughts on TN, why not go to the source? See below. The logic is
fantastic: if it's possible to use 86% Lead for your boards, then it's OK to
use Lead. If it's only 84%, then it's forbidden.
/Inge
RoHS Directive (2002/95/EC)
These original exemptions were published within the annex to RoHS on 27
January 2003. These exemptions are currently in force.
1. Mercury in compact fluorescent lamps not exceeding 5 mg per lamp.
2. Mercury in straight fluorescent lamps for general purposes not exceeding:
halophosphate 10 mg
triphosphate with normal lifetime 5 mg
triphosphate with long lifetime 8 mg.
3. Mercury in straight fluorescent lamps for special purposes.
4. Mercury in other lamps not specifically mentioned in this Annex.
5. Lead in glass of cathode ray tubes, electronic components and fluorescent
tubes.
6. Lead as an alloying element in steel containing up to 0,35 % lead by
weight, aluminium containing up to 0,4 % lead by weight and as a copper
alloy containing up to 4 % lead by weight.
7. Lead in high melting temperature type solders (i.e. tin-lead solder
alloys containing more than 85 % lead),
lead in solders for servers, storage and storage array systems (exemption
granted until 2010),
lead in solders for network infrastructure equipment for switching,
signalling, transmission as well as network management for
telecommunication,
lead in electronic ceramic parts (e.g. piezoelectronic devices).
8. Cadmium plating except for applications banned under Directive 91/338/EEC
(1) amending Directive 76/769/EEC (2) relating to restrictions on the
marketing and use of certain dangerous substances and preparations.
9. Hexavalent chromium as an anti-corrosion of the carbon steel cooling
system in absorption refrigerators.
10. Within the procedure referred to in Article 7(2), the Commission shall
evaluate the applications for:
Deca BDE,
mercury in straight fluorescent lamps for special purposes,
lead in solders for servers, storage and storage array systems, network
infrastructure equipment for switching, signalling, transmission as well as
network management for telecommunications (with a view to setting a specific
time limit for this exemption), and
light bulbs,
as a matter of priority in order to establish as soon as possible whether
these items are to be amended accordingly.

ฤmne: Re: [TN] Military Exemption from Lead-Free?
Military is not EXEMPT, it is OUT OF SCOPE. The directive does not
apply at all to military (other than the indirect massive impact the
directive has had). The directive has no legislative control over
military electronics.

No specific alloy is "forbidden" in military electronics.
In general, solders and fluxes are categorized per and must comply with
J-STD-004, J-STD-005, and J-STD-006.
Specific solder alloy types are called out on assembly prints and BOMs
per MIL-STDs and Weapon Specs.
Military, traffic control, industrial safety, some medical, and many
other products are exempt per RoHS and IEEE exemptions.

Check out
Air Force's Airworthiness Advisory AA-05-01 It isn't very forceful in
the wording, but is the closest thing I could find so far to support my
cause. If anyone knows of any documentation forbidding lead free in
military products, I would sure appreciate a heads-up.
Thanks,
Dave

Subject: Military Exemption from Lead-Free?
I believe that I remember someone mentioning a military end-use
exemption from lead free requirements. Am I remembering correctly or is
this just wishful thinking? If it is true, can anyone point me in the
direction to get it in writing?
Thanks!
