Interpetation EN ISO 15626: Maximum allowable length for thickness range

Hello to all.

I have a query regarding the maximum allowable length for thickness range in the EN ISO 15626 (Look at the image).

For example, if we have a thickness of 30mm the maximum allowable length according to the table is (lmax) = 30mm * 1,5 = 45mm (but max 60mm ?). What is the acceptance lmax, 45mm or 60mm? Over 45mm or over 60mm is rejected?

If over 60mm is rejected what the reason to mention on the standard (1,5*t) for thickness range 15mm to 50mm? Τhe same problem applies to the thickness range 6m to 15mm.

Thank you!

for thickness of 30 is 45 mm. for thickness of 41 or greater it is 60 maximum.
30x1.5=45 mm

40x1.5=60 mm

41x1.5=61.5
if it is larger than 60 mm, then 60 mm

Just have to go by the book.
