Annex I (Essential Safety Requirements) chapter 3.1.3. (Non-destructive tests) of the PED directive states:
“For pressure equipment, non-destructive tests of permanent joints must be carried out by suitable qualified personnel. For pressure be approved by a third-party organization recognized by a Member State pursuant to Article 13.”
