Specifications for permanent paper

From: Maxim Osinovsky <mosinovs>
Date: Wednesday, January 15, 2003
Does anyone know where to get reliable information on specifications
for archival quality paper, like those listed at
<URL:http://palimpsest.stanford.edu/byorg/abbey/napp/std.html> :

    pH
    alkaline reserve(CaCO3 equivalent)
    tear resistance
    lignin content

I don't have yet access to the full text of North American Permanent
Papers, but it looks like the information contained therein is often
grossly incomplete. This is all the book has to say about the brand
similar to that we are using most often for preservation
photocopying:

    Fox River Paper Co.: Howard Permalife Bond and Ledger are both
    watermarked as Permalife. They are also both 25% cotton. Call
    800-558-8327

I also have an impression that manufacturers tend to suppress this
information because it is not in their best interests to disclose
it.
