Your Trusted PED Certification Consultant
PED certification meaning: The Pressure Equipment Directive (PED) 2014/68/EU is a mandatory European Union regulation that defines the essential safety requirements for pressure equipment design, manufacturing, and conformity assessment procedures. Understanding what is PED certification is crucial for manufacturers seeking to enter the EU market.
RASOO is a specialized technical service organization focusing on international compliance certification for industrial equipment products. With authorization from multiple EU PED certification bodies, we provide comprehensive PED certification services across global markets including Europe, Americas, and Asia-Pacific regions.
Our Global Presence:
The PED (Pressure Equipment Directive, Directive 2014/68/EU) is one of the European Union's mandatory technical regulations. It stipulates that all pressurized equipment with a design pressure ≥ 0.5 bar (gauge pressure) must comply with this directive before being placed on the EU market.
Core Objectives:
| Chapter | Content Overview |
|---|---|
| Chapter I | Scope and Definitions |
| Chapter II | Making available on the market and CE marking |
| Chapter III | Economic operators obligations (manufacturers/importers/distributors) |
| Chapter IV | Conformity assessment procedures |
| Chapter V | Notified body and surveillance |
| Chapter VI | Final provisions |
PED applies to the following pressurized equipment or components:
| Category | Examples |
|---|---|
| Pressure Vessels | Air storage tanks, compressor receivers, heat exchangers, boiler bodies, etc. |
| Piping | Industrial pipeline systems for steam, gas, liquid transportation |
| Safety Accessories | Safety valves, safety diaphragms, pressure limiting controllers |
| Pressure Accessories | Pressurized valves, connectors, filters, distributors, etc. |
| Assemblies | Multiple equipment combined as one unit (e.g., refrigeration system assemblies) |
One core aspect of PED is classifying pressure equipment into four risk levels (Category I ~ IV) based on potential hazards, plus SEP (Sound Engineering Practice) equipment that doesn't fall under classification.
| Category | Risk Level | Management Mode |
|---|---|---|
| SEP | Non-mandatory | Only need to comply with "good engineering practice" |
| Category I | Low risk | Module A |
| Category II | Medium risk | Module A1 / D1 / E1 |
| Category III | High risk | Module B + F / D / E |
| Category IV | Highest risk | Module B + D / G / H1 |
Each category corresponds to different conformity assessment procedures (Modules). The following table summarizes the applicable scenarios for each module:
| Module | Name | Responsible Party | Features |
|---|---|---|---|
Module A |
Internal production control | Manufacturer | Company self-inspection, low risk |
Module A2/A1 |
Internal production control + supervision | Notified Body | Regular supervision by organization |
Module B |
EU type examination | Notified Body | Design type review |
Module C/C2 |
Type conformity declaration | Manufacturer + Notified Body spot checks | Batch consistency execution |
Module D/D1 |
Production quality assurance (ISO 9001 for PED Module D) | Manufacturer + Notified Body | Production quality system audit |
Module E/E1 |
Product quality assurance | Manufacturer + Notified Body | Focus on final inspection |
Module F/G |
Product verification / unit verification | Notified Body | Product-by-product inspection |
Module H/H1 |
Full quality assurance | Manufacturer + Notified Body | Highest level, including design review and system audit |

Understanding the PED certification process is crucial for successful compliance. The PED certification time typically ranges from 2-5 months depending on complexity:
Determine if product falls under PED jurisdiction, identify fluid group, volume, pressure, and decide risk category (SEP ~ IV)
Select appropriate PED modules based on product risk level and decide if PED notified body participation is required
Design must follow PED essential safety requirements (Annex I), prepare PED risk assessment report complying with harmonized standards
Prepare drawings, PED design calculations, risk analysis, PED material certification, PED welding requirements, inspection plans
If applicable, PED notified body audits ISO 9001 level system for Module D/D1/E/E1/H/H1
Notified body reviews sample or witnesses hydraulic/pneumatic testing (Module B) or product inspection (Module F/G)
PED notified body issues conformity certificate (EU Type Examination Certificate or QA Certificate)
Prepare EU Declaration of Conformity
Affix PED CE marking with PED notified body identification number, retain PED technical file for at least 10 years
The PED technical file must contain at minimum:
| Item | Description |
|---|---|
| Product Description | Model, structure, purpose, working conditions |
| Design Drawings & Assembly Diagrams | Overall drawings, weld layout drawings, material numbering |
| PED Design Calculations | Wall thickness, stress calculations, stability analysis, fatigue calculations |
| PED Material Certification | Material grades, test reports, EN standard comparison, PED materials 3.1 3.2 certificates |
| PED Welding Requirements Documents | WPS, PQR, PED welder qualification certificates (WPQ) |
| Inspection & Test Plan (ITP) | Control process from incoming inspection to final testing |
| Test Reports | Non-destructive testing (NDT), hydraulic testing, leak testing, etc. |
| PED Risk Assessment | According to ISO 12100 and PED Annex I requirements |
| Quality Control Content | Flowcharts, inspection points (Hold Points) |
| Declaration of Conformity (DoC) | EU conformity declaration signed by manufacturer |
| Notified Body Documents | Audit reports, certificate copies, etc. |
| Role | Main Responsibilities |
|---|---|
| Manufacturer | Design, manufacture and ensure product meets PED; prepare PED technical file; issue DoC; affix PED CE marking |
| Importer | Confirm supplied products have completed PED conformity assessment, retain document copies |
| PED Notified Body | Audit, inspect and issue conformity certificates; identification number appears in PED CE marking |
| Distributor | Ensure product CE marking is correct and directive documentation is complete |
| Question | Answer |
|---|---|
| What is the relationship between PED and CE marking? | PED is one of the EU CE marking regulatory requirements, belonging to the "Pressure Equipment Directive" of CE. |
| Does my product under 0.5 bar need PED certification? | No. Products below 0.5 bar do not fall under PED scope and exclusions. |
| What is the relationship between PED vs ASME? | No direct relationship. ASME is an American standard; PED is an EU regulation. ASME design basis can be used, but must meet EN requirements. |
| Can I get PED certification without a quality system? | Category I can use internal control only; higher levels require a quality system (ISO 9001 foundation). |
| Is PED certification valid for life? | Design type certificates have no fixed period, but require reassessment if design changes or standards update. Quality system certificates are reassessed every 3 years. |
| What is the relationship between PED and EN standards? | The directive is "law", PED harmonized standards are the "technical compliance path", such as EN 13445, EN 13480. Designing to these standards provides presumed compliance. |
| Can a PED notified body be a Chinese organization? | No. Must be an organization designated and notified by the EU Commission (NB number see NANDO database). |
