The product(s) used for approval testing (see Sec.3) will place limitations on the range of approval. The approval will be limited to the type of steel hollow section (i.e. circular/rectangular) and manufacturing method (welded/seamless) as indicated in App.A.

The applicable scope of approval depends on the dimensions presented and tested for the qualification tests. As a rule the dimensional limits in Table 1 apply. If deemed necessary by the Society, different dimensional limits may apply.

The wall thickness of the hollow section covered by the approval is related to the scope of testing and the actual wall thickness presented in the approval test. If deemed necessary by the Society, different limits on the wall thickness may apply.

Applicable approval for wall thickness for hollow sections without impact tests (< 6 mm) is limited to max. 6 mm.

Applicable approval for wall thickness for hollow sections with impact tests (? 6 mm) is limited to the maximum thickness of the tested product.
