This report presents the results of Phase III research
of an industry-government consortium study to develop
nonproprietary data on the performance of tape-bonded
seams of EPDM (ethylene propylene diene terpolymer)roof
membranes. Four Phase III tasks investigated the
effects of: (I) elevated test temperatures, (II)
elevated temperature exposure prior to loading, (III)
exposure to industry-developed protocols (i.e., Rubber
Manufacturers Association and SPRI), and (IV) cold
temperature preparation on peel creep-rupture response
and on peel strength. Task (V) examined shear testing.
Two commercial tape systems (i.e., tape and primer) and
one liquid adhesive were applied to well-cleaned EPDM
rubber in fabricating specimens. For each task,
comparisons of the creep-rupture responses and strengths
of tape-bonded and liquid-adhesive-bonded samples were
