Eight sealants, commercially available in Japan (see Table 1), which are conforming to JIS A 5758  and are tested in accordance with JIS A 1439 , were used to carry out the exposure test.
The configuration of the test specimen that enabled exposure of the sealant to continuous degrees of extension and compression in a single specimen is shown in Fig. 1.
