I give allot of credibility to Jon, he has certainly helped us along the
way.  My approach is one I have used here and was only a suggestion that
came from an earlier interpretation of a certain RBOC checklist.  From my
limited experience, the best avenue is to work with RBOC that will be
reviewing your information.  I found that the only interpretation that
matters in the end belongs to the reviewer!
Have a nice weekend- John

John is right.  This has been our experience too.  We created a spreadsheet
from the BOM, contacting each vendor and entering the data.

Here's an example of our database:

Part Number     Description     Manufacturer    P/N     Flammability
Classification  Polymer Type    Total Mass Polymer (g)  Polymer, %
Oxygen Index
 5xx-000xx-01    RES,100K,TKF,1/16W,1%,SM,0603  DALE    CRCW06031003F   UL
94 V-0  Thermal Set Epoxy       0.000036        1.57 (Total: 0.0023g)
22-25
5xx-000xx-01    IC,3966,LDO REG,1.8V,3A,TO263-5 NTL     LP3966ES-1.8    UL
94 V-0  Epoxy Cresol Novolac    0.88    60.7 (Total: 0.1.45g)   28
5xx-000xx-01    IC,3966,LDO REG,2.5V,3A,TO263-5 NTL     LP3966ES-2.5    UL
94 V-0  Epoxy Cresol Novolac    0.88    60.7 (Total: 0.1.45g)   28
5xx-000xx-01    CON,2MM,HM-A,22X5-ROW,RCPT,RA,P-FIT     AMP     100147-1
UL 94V-0        Housing: Thermoplastic polyester GF PBT or GF PBT/PC Blend
color grey      7.181           29

Make sure you get all the alternate vendors too.

It took us a few months to generate our list and it is constantly
maintained.  A small price to pay for a happy customer.

Good luck,

Dave,
You can get this information by looking through your BOM, finding the
component vendor, checking their website, emailing their contact, waiting a
few days, and calling them on the phone if they do not respond.  Your email
message needs to be nothing more than what you stated below (from personal
experience).  (are you the Dave Wilson once upon a time from Wang Labs?)

Thanks John - I figured it wouldn't be an easy ride!

Can you point me in the right direction as regards discovering the polymeric
weight and oxygen index of particular components?

Thanks again,

Dave

Hi Dave,

I asked Verizon at the Las Vegas conference if they wanted a report from
an independent source to support GR-78 compliance and they indicated at
that time that they did not feel that was necessary.

At Curtis-Straus, we routinely put together an assembly level flame
database for every complete GR-63 report we produce. The Verizon
checklist says that you need to provide it if they ask for it.
