EN13445 Testing Category 4

[ivanrogers]

Table 6-1 Shows the maximum allowed values for the nominal design stress.

Normally for test category 4 the nominal design stress is multiplied by 0.9.

Does this also apply to the nominal design stress for bolts in "11.4.3 Bolting" for the test category 4 case?

I would say no.
As I see it the 0.9 is used to increase the shell thickness to compensate for not having to do any NDT, this is usually not applicable to bolts.

But if you want an official answer regarding this, then you can fill out this form:
