The testing was conducted in accordance with the test method defined in ISO/ FDIS 28278-1. After an initial conditioning period of 28 days at (23 ± 2)°C and (50 ± 5)% RH, five test specimens were exposed to a salt spray atmosphere which was maintained for 480 h. After salt spray exposure, the test specimens were elongated in tensile to their breaking point and tensile stress, elongation at break, as well as the type of rupture was determined. From the stress/strain curve, also the Young’s modulus was determined. As reported in Table 4, essentially all specimens tested exceeded the requirement (DXmean > 0.75 and rupture > 90 % cohesive) without problems. Only sealants B-3 and B-4 showed adhesive failure.
