Abstract: The ability of a joint sealant to withstand the diurnal and seasonal cyclic movements imposed by variations of temperature, and in some cases of moisture content, of the adjoining claddings on buildings, without loss of adhesion to joint surfaces or other failures, is of primary importance for its long-term performance.
This paper reviews the laboratory test methods, which have been developed to assess this property, from national and international standards. Some simpler test methods for assessing the ability of sealants to withstand maintained extension are also briefly discussed. A number of test apparatuses are described which subject sealants samples simultaneously to cyclic movements and to weather and thus simulate the likely effects of service conditions more closely than is yet possible in laboratory tests.
An attempt is made to evaluate the "State of the Art" of assessing the movement capability of building joint sealants, and recommendations are made for future work in this field.
