    Additional information:
    RIGIDITY:
    The external diameter of the tubes from the following nanoforms are compliant with the current
    SIP criteria (d90 =< 30nm):

    - [FT7000] (d90= [12.9]nm)
    - [FT9100] (d90= [17.6]nm)

    It is understood that the previously tested nanoform BAYTUBES™ C150P also met d90 =<
    30nm, as the producer defined the original SIP criteria.
    The tube’s thickness and diameter are not expected to confer them structural rigidity. The curved
    and entangled morphology of these nanotubes observed with electronic SEM/TEM microscopy
    (see Section 1.4.) supports the hypothesis that thin nanotubes are flexible.

    The marginal presence of thicker tubes has also been checked: all maximal
    external diameters observed were smaller than the threshold value 30nm.
    - [FT7000] (dMAX= 25.3nm)
    The complete diameter distribution curves may be found in Section 1.4.
    Fraction of constituent particles in the size range 1-100 nm:
    >= 99 - <= 100 %
