Test: weld imperfections to ISO 6520-1, ISO 5817 levels and symbols
Fourteen questions about what shows on the weld and what stands on the
drawing: the imperfection number to ISO 6520-1, its cause, the ISO 5817 quality
level and the parts of the symbol. Checked in your browser — the answers go
nowhere.

This is a self-check of theory from the pages of this site. It is not a welder certificate and does not replace the EN ISO 9606 test: qualification comes from a practical examination before an authorised examiner, with the test piece examined.
Where the questions come from
The questions are not typed out here: they are built from the same functions
that print the imperfection table, the ISO 5817 level table and the breakdown of
the symbol. That is why an answer cannot drift away from a table — it is the
same number.
