Tensile strength is the test
results which are commonly tested for water proofing membranes. This is an
important which tells that the membrane perform or not. (Work performance being
the amount of distortion the membrane will undergo without destruction.) All
roofing membranes undergo stresses and strains which
cause the membrane to distort or deform. Membrane, over its lifetime, will
undergo many cycles of stress; normally due to changes in atmospheric temperature. The membrane must be
able to cope with the forces it encounters in order to protect the system from
intrusion by water. Testing for tensile strength is performed using a
mechanical testing apparatus. Specimens of membrane are stretched to the
breaking point and in doing so, the tensile strength is determined.
TENSILE STRENGTH - Tensile
strength is defined as the force required to break the specimen or cause complete separation of constituents in a
linear direction.
