Notes to Table 4.2.4:

Footnote 1

The "/" indicates that a test sequence was performed (e.g., a heat aging test was performed followed by a tensile strength test).

Return to footnote 1 referrer

Footnote 2

The tensile strength is expressed in force unit per metre width of the specimen due to the particular behaviour of the multi-layered membrane.

Return to footnote 2 referrer

Footnote 3

The original values for tensile strength are shown in Table 4.1.1 of this Report.

Return to footnote 3 referrer

Footnote 4

The aging test sequences were conducted with specimens that showed the weakest tensile test results prior to aging either in the machine or cross-machine direction.
