AFIAPRequirements for In-service
inspection
• periodical inspections
Requalification• internal & external inspections before hydrotesting• verification of security devices• hydrotesting
French enforcement order of March 2000
every 18 to 40 months
every 10 years
• covered by the user’s inspection program• requires an approval from a third part inspection body

AFIAPTo conclude
• has been recognized in France in order to replace hydrotesting by in-service AE testing (DM-T/P 32970)
• helps customer and authorities be confident about the way AE is conducted & how results are obtained
• needs to be completed new type of equipment
• needs continuous feed back from REX critics are very welcome
the AFIAP AE good practice guideline :
