ISO 13715-2019 Edges of Undefined Shape - Indication and Dimensioning

What does "t=3" signify in figures 21 & 22? If there is language in the 13715 standard pertaining to it, then I am entirely missing it. Is this a symbol that is described in a different ISO standard?

Thank you very much.

Figures illustrate situation when only one view is represented and the outlines of both front and back are the same.

So, in absence of second view "t" must refer to "thickness".

CheckerHater,

Specifying thickness would be my guess. Do you know that, or are you guessing too?

With 3D[ ]CAD, I strongly prefer a side view with a dimension applied to the thickness, especially when it turns out the thickness is not 3mm.

Don't have standard book, but it seems pretty common:
