AFS 2005:2 – Definitions
 Installation – All pressure retaining devices erected within the
operational area of a workplace
 Workplace – The existence of an employer in control of the same.
Permanent workplaces are listed in a register kept by Statistics
Sweden (SCB
 Processing plant - Several pressure retaining devices together
making up an integrated, functional unit intended for a particular
process
 Protection circuit - Part of a processing plant or an installation
which is separately protected and can be shut-off from the process
or the rest of the installation

AFS 2005:2
Section 14 - Classification of installations
 Protection circuit ”requirement G”: Contains vessels requirement
G, pressure equipment category I or simple pressure vessels
PxV>200 barlitres
 Protection circuit ”requirement K”: Contains vessels requirement
K, pressure equipment category II, III and IV or simple pressure
vessels PxV>1000 barlitres

AFS 2005:2
Section 15 - Classification of installations
 A party erecting a processing plant or part of an
installation (not an assembly) and comprise one or
more pressure containment circuits subject to
requirement G, shall draw up installation
documentation with a P&ID
 It shall contain a description of the extent of the
installation and its division into protection circuits
 In order for the protection circuits to be classifiable as
provided in Section 14, a list of the assemblies and
devices to be included is required, together with
requirement specifications.

AFS 2005:2
Section 17 – Essential safety requirements
Processing plants or other parts of installations consisting of
protection circuits which are subject to requirement G (not
assemblies) shall meet the essential safety requirements for
installations as stated in Annex 1

AFS 2005:2
Section 18 – Installation ”control” (Plant inspection)
 Processing plant or other parts of installations
consisting of protection circuits subject to
requirement K, may be put into service only if they
have undergone installation control as provided in
Sections 19 and 20.
 The control shall have been carried out by an
inspection body.
9
AFS 2005:2
Section 19 – Installation control
 Installation control shall have included examination
of compliance with the requirements of Section 17.
The installation documentation prepared in
compliance with Section 15 and the requisite
instructions for erection shall have been examined
prior to erection
 The installation shall have been examined after
erection, to verify that it is constructed in compliance
with assessed installation documentation,
instructions for erection and these Provisions, and
that there are no deviations important for safety.

AFS 2005:2
Section 20 – Installation control
 The installation control shall have included design
review (Section 10) and manufacturing inspection
(Section 11), of joints between the following items:
•vessels subject to requirement K
• pressure equipment in categories II, III and IV
• simple pressure vessels with PxV exceeding 1,000
bar litres,
• connected pipelines subject to requirement K
• Pressure accessories and safety accessories
pertaining to the said devices
