Library of Congress Topics in Preservation Series (TOPS)

From: Ray Privott <rpri<-a>
Date: Friday, August 15, 2014
"Evaluating Storage Materials: Alternatives to the Oddy Test"
Topics in Preservation Series Lecture, Preservation Directorate at
    the Library of Congress
Library of Congress
Washington, DC
James Madison Memorial Building
101 Independence Ave SE
Dining Room A, Sixth Floor
September 4, 2014
10:00-11:00 am

The lecture will be webcast.  To tune in, please send an email at
least three business days in advance to Ray Privott, rpri<-a t->loc< . >gov.
The number of webcast "seats" is limited and will be filled in the
order in which the requests are received.

The Library of Congress has a quality assurance program for testing
materials that come into contact with collections in storage or on
display to ensure those materials will not harm collections.  The
traditional Oddy test assesses the impact of material off-gassing on
collection items through the corrosion of metal coupons, a result
that does not necessarily correlate well to the Library's primarily
paper-based collections.  Dr. Eric Breitung will discuss research in
the Preservation Research and Testing Division that uses paper
instead of metal as a sensor and multiple analytical methods to
assess the degradation level of the paper sensor.  Common book and
paper preservation materials such as book cloths, binding boards,
foams, and adhesives were subjected to accelerated aging in the
presence of Whatman filter paper and the traditional Oddy metal
sensors, then evaluated with ion chromatography (IC) and
ultraviolet-visible (UV-Vis) spectroscopy.  Of significant interest
was the analysis of corrosion products formed on the metal coupons
with x-ray diffraction (XRD).  The assessment of the impact of these
specific products on collection materials to better understand the
often contradictory results obtained from the Oddy test, and how a
new test might better inform the paper conservation community, will
be discussed.
