AFS 2017:3 (Användning och kontroll av trycksatta anordningar) |
1. Purpose
This document provides a ready-to-use inventory register for pressurised vessels compliant with AFS 2017:3 (Arbetsmiljöverket). It is intended for use by operators (brukare) who need to maintain a förteckning (register) of all pressurised equipment on site.
The inventory satisfies:
- AFS 2017:3 — Swedish regulation for use and inspection of pressurised equipment
- PED 2014/68/EU — Pressure Equipment Directive (as implemented in Sweden via AFS 2016:2)
- ISO 9001:2015 clause 7.1.5 — Monitoring and measuring resources
Lagkrav: Enligt AFS 2017:3 ska brukaren föra en förteckning över alla trycksatta anordningar som omfattas av föreskrifterna. Förteckningen ska hållas aktuell och vara tillgänglig för tillsynsmyndigheten.
2. Regulatory Classification — AFS 2017:3
2.1 Scope
AFS 2017:3 applies to pressurised equipment that meets the following criteria:
| Equipment type |
Threshold for inclusion |
| Pressure vessels |
PS > 0.5 bar and PS × V > 50 bar·L |
| Piping |
PS > 0.5 bar and PS × DN > 2000 bar·mm |
| Steam/hot water boilers |
PS > 0.5 bar |
Equipment below these thresholds is not covered by AFS 2017:3 but may still be subject to general workplace safety requirements (AML).
2.2 Classification (Klass A and Klass B)
| Klass |
Criteria |
Inspection requirement |
| Klass A |
Higher risk — per AFS 2017:3 tables based on PS, V, medium, and fluid group |
Must be inspected by an ackrediterat kontrollorgan (accredited inspection body: Kiwa, DEKRA, DNV, TÜV, Bureau Veritas, Apave) |
| Klass B |
Lower risk — below Klass A thresholds but above AFS 2017:3 scope threshold |
May be inspected by the operator’s own competent personnel with documented competence |
2.3 Fluid Groups (PED 2014/68/EU, Article 13)
| Group |
Definition |
Examples |
| Group 1 |
Dangerous fluids — explosive, flammable, toxic, oxidising |
Ammonia, LPG, acetylene, chlorine, hydrogen |
| Group 2 |
All other fluids not in Group 1 |
Compressed air, nitrogen, water, steam, hydraulic oil |
2.4 PED Categories (for reference)
| Category |
Risk level |
Conformity assessment |
| Art. 4.3 |
Below PED threshold — no CE marking required |
Sound engineering practice |
| Category I |
Low risk |
Internal production control (Module A) |
| Category II |
Medium risk |
Internal + monitoring (Module A2, D1, E1) |
| Category III |
Higher risk |
Type examination + production QA (Module B+D, B+F, etc.) |
| Category IV |
Highest risk |
Full QA + type examination (Module B+D, B+F, G, H1) |

Notes:
- Intervals may be extended with documented risk assessment approved by the accredited inspection body
- Intervals may be shortened for corrosive service, high-temperature hydrogen attack, CUI risk, or other degradation mechanisms
- After repair or alteration, a new första kontroll may be required
3.3 Operator Obligations (Brukarens skyldigheter)
Under AFS 2017:3, the operator shall:
- Maintain an up-to-date förteckning (this document)
- Ensure all inspections are performed on time by qualified parties
- Keep all documentation accessible — inspection reports, certificates, drawings
- Perform regular tillsyn (supervision/monitoring) between formal inspections
- Report incidents to Arbetsmiljöverket
- Ensure personnel are competent (documented training per JDS-PRO-009)
- Have written routines for operation, maintenance, and emergency procedures
