AFS 2005:3 Terms of use
 Pressure equipment which must be inspected by an inspection
body may only be used if inspections has been performed, and the
result was satisfactory
 Inspection body assess highest / lowest pressure and temperature
for each pressure equipment (and the safety circuit)
 Inspection body assess the peeriod to next internal and external
inspection
AFS 2005:3 Inspection
 Installation inspection
 Periodice inpsection (in-service inspection) - DP and IU
 Revision inspection
AFS 2005:3 Installation inspection
 Equipment in class A and B
Exclusion:
- Storage tank without safety equipment
- Assembly acc to PED
 Before Installation inspection: AFS 2005:2 Plant inspection
AFS 2005:3 Installation inspection
 Performed before (or in addition to) first time of
operation
- Equipment needed for safety exists and works
satisfying
- The pressure equipment and the system is suitable
regarding safety
- All risks regarding operation and malfunction have been
assessed
AFS 2005:3 Periodic inspection
 Operational test (Driftprov) – class A and B
Consists of:
Functional test of safety equipment
System check
- Functional test of safety equipment can be performed as
self inspection if conditions acc to 36-37 §§ are fulfilled
- System check can be performed as continous
surveillance acc to AFS 2002:1 if conditions in 15 §, third section,
are fulfilled
AFS 2005:3 Internal and external inspection (IU)
 Equipment in class A
 Inspection performed in order to assess that no
defects or other deviations which could be harmful
regarding safety
Exclusion:
- cryogenic vessels
AFS 2005:3 Internal and external inspection (IU)
- Visual inspection
- Ultrasonic testing or other volumetric NDT-method
- Crack testing (MT or PT)
- Measure of thickness
- Special program for inspection
- Observations at continous surveillance shall be
considered
AFS 2005:3 Revision inspection
 Pressure equipment in class A and B
Perfomed on pressure equipment which:
1. has undergone significant repair or change
e.g. Exchange of pressure part, repair of weld, seal welding of crack
in pressure part.
2. Is liable to have been damaged
e.g. Out of operation without corrosive preventing measures (inert
gas filling)
3. Shall be used after a substantial change in working
conditions
4. Is stationary and has been moved
5. Shall be used after the expiry date set by the manufacturer
