This report is the first in a series of publications on
performance criteria for built-up roof membranes. The
development of a performance approach to bituminous
built-up roof membranes is described and preliminary
performance criteria are recommended. A number of test
methods have been developed in order to obtain data to
evaluate roofing membranes against the recommended
criteria. Twenty attributes that effect the performance
of roof membranes under service conditions are
identified and laboratory tests are described for
measuring the engineering properties of the membrane
that pertain to many of these attributes. A level of
performance is recommended for nine of the identified
