GB151 comes in two types of hooks and loops, labeled A and B. Could you please tell me when to use each one?

You can take a look at the definition of 151; if I remember correctly, the mainstream format nowadays is B

For Type A hooks, calculations are required; for Type B hooks, the thickness of the tube sheet is added to 30 mm. Isn’t Type B used in most cases these days? ! Is there no distinction in when to use type A and type B hook loops?
