Location : Mississippi, USA
Study
: AWPA E1 Standard Testing for
Resistance to
Formosan Termite
Dates : August 2007 - September
2007
The Mississippi
State University Department of
Forest Products’ Forest & Wildlife
Research Centre is a world renowned
test centre for
Formosan termites.
With many of the southern states of
the US encountering serious economic
losses from the activities of the
Formosan termite, the MSU was an
ideal facility to test the PPL Field
Liner material in laboratory
conditions.
The testing
carried out at MSU was designed to
conform with and exceed the
requirements of the American Wood
Protection Association (AWPA)
standard E1 (as required within the
P20 standard for ‘Barrier Wraps’. )
The fundamentals of the test
programme are described below and
the results will be published as
soon as available. The information
below is an extract from the agreed
testing programme.

EVALUATION OF BARRIER WRAP
BACKGROUND
Protective
Packaging Limited contacted the
Forest Products Department (FPD) to
discuss initiating a research
program with their products. This
proposal covers the initial program
of investigation. Additional
studies may be proposed as addenda
to this proposal and conducted as a
data base is developed.
PROCEDURE
AWPA E1
Standard Method for Laboratory
Evaluation to Determine Resistance
to Subterranean Termites
Method: Southern yellow pine
specimens will be prepared by FPD
and sent to the sponsor to be
covered by the sponsor’s product.
These samples prepared for exposure
by the sponsor will then be returned
to the FPD for inclusion in testing.
Untreated southern pine controls and
southern pine blocks treated with
CCA will be included for
comparison. No choice and choice
testing will be conducted with
Coptotermes formosanus. The
tables below show the study design.
