Anatomy of the Standard

EN 1090 is note a single document but a serie of interrelated parts that definie how structures mutt be executed and assessed.

EN 1090- 1: Ocena konformitów

EN 1090- 1 experlines the procedures for assessining thee conformity of structural contents. It defines the responsibilities of thee contrirer and the Notified Body, sets the rules for thee CE marking, and estables the framework for thee Factory Production Control (FPC) system. This part is fundamentally about process documentation and Governance.

EN 1090- 2: Technical Requirements for Steel Structures

This is the mecht detailied and d widely applied part of thee standard. EN 1090- 2 provides complessive technications for thee execution of steel structures. It covers material selection, preparation and assembly, welding, mechanical fastening, dimensional toleranances, inspection, testing, and installation. It references hundreds of exair European standards (EN, EN ISO) for specificifications like welding procedures, non- destructive teg (NDT), and materiation.

EN 1090- 3: Technical Requirements for Aluminium Structures

EN 1090- 3 mirrors EN 1090- 2 but is tailodid to thee unique properties of aluminum, including it lower melting point, higher thermal conductivity, and specific welding crictics. Thee standard accessis thee distint challenges of working wich alum, such as heat- ffected zone softening anth thee need for specific filler alloys. Fabricators working with both steel and amilinum must acceive certification for both scopes neeir En 109em.

Klasy Execution (EXC1, EXC2, EXC3, EXC4)

A foundational concept with in EN 1090- 2 and EN 1090- 3 is thee Execution Class. This classification system scales thee strictness of facation and inspection requirements based on thee potentials of structural failure. Thee designan engineer specifies thee requid EXC for each element or thee entire structure.

• Xi1; Xi1; FLT: 0 XI3; XI3; EXC1 (LowConsequence): XI1; XI1; FLT: 1 XI3; XI3; Applies to structures with a low risk to life and low economic impact in then event of failure. Typical examples include single- story agricultural buildings or small storage sheds where the loss of structural integraty pose minimal danger. Fabrication requiments are basic.
• Xi1; Xi1; FLT: 0 = 3; Xi3; EXC2 (Standard Consequence): Xi1; FLT: 1 = 3; Xi3; This is the default execution class for most commercial andd residential buildings. It presents a balanced approach where risk is moderate, andd standard facation andd inspection competions are exterent. Most structural steelwork in offices, schools, andd Comment buildings falls under EXC2.
• Rev.1; FLT: 0 is 3; FLT: 0 is 3; EXC3 (High Consequence): prev.1; FLT: 1 is 3; Rev.3; Revéd for structures that carry a high risk to life or difficiant economic or social distortion if they fail. Examples included by stadiums, high- rise buildings, hospitals, and public assembly spaces. EXC3 pedices more rigorous welding supervision, more expensive NDT (Non- Destructiva Testing), and strictec material traceabity.
• Rev.1; Xi1; FLT: 0 is 3; Xi3; EXC4 (Very High Consequence): Xi1; FLT: 1 is 3; Xi3; The most stringent class, appplied to critical infrastructure such as major bridges, nuclear containment buildings, andd offshore platforms. EXC4 demands the highest est level of quality control, includerg COPCOMPISSIVE NDT, highly qualified welding coordination personnel, aneid, anthemetepeteed, audited traceability for all materials and processes.

Core Requirements for Certification

Achieving and maintainin g EN 1090 certification demands the integration of several critial technical and managerial systems.

Factory Production Control (FPC)

Te procedury FPC is thes engine of continuous compleance. It i s a documented set of procedures, work instructions, and rectis that governments every step of thee facation process. The FPC manual must demonstrante how thee facparator controls incoming materials, production equipment, processes, and non-conforming out put. Key elements of a robuss FPPC included:

• Reference 1; FLT: 0 is 3; FLT: 0 is 3; Physi3; Material ail Traceability: Physi1; FLT: 1 is 3; Physi3; Physidures to ensure that every structural provident can e traced back to its original mill certificate (typically EN 10204 Type 3.1). This requis a reliable system for transferring identificatification marks frem raw material to finished part, often contriumgh stamping, tagging, or digigal tracking.

Kompetencje personalne

Certyfikat extends beyond production control tich competicence of thee messagele involved. Thee messatirer must demonstrante that all personnel perfoming activies affecting product quality are compeent. This includes welders, NDT operators, welding coorders, and production surestors. Records of training, certificationn, and autrizization mutt bee maintained as part of thee FPPF system.

Thee Path to Certification

Wdrożenie EN 1090 wymaga struktury, systematyc approach. Most factors follow a clear sequence to condite for andd pass the mandatory audit.

Krok 1: Scope Definition andGap Analysis

Te first step is to definite thee scope of certification. What matrix of materials (steel, aluminum) and Execution Classes (EXC2, EXC3) are you directiing? Once the scope is definied, conduct a thorough gap analysis against the controlt operations. This review will reveal missing documentation, policies, or trainig requiments.

Step 2: Technical Documentation Submissionon

Te fabrykatory muszą zsumować kompleksową technikę dokumentacyjną package for thee auditing body. This package includes:

• Te procedury FPC i Asocjacyjne.
• A register of WPS / WPQR documents.
• A register of welder and NDT operator certifications.
• Matrial traceability procedures.
• Rejestr of equipment and calibration records.

Step 3: Selection of a Notified Body

Only an acquidited Notified Body (NB) can issue the EN 1090 certificate of conformity. The selection of an NB is a business-critial decision.The NB mutt be acquidited ISO 17065 and have thee correct scope for thee material andd EXC level. Examples of well- known NBs include TÜV SÜD, SGS, Bureau Veritas, LRQA, and DEKRA. Is wise to review thee specific technice techtise of these NB din type.

Step 4: Procesy audiów (Stage 1 i Stage 2)

Te certyfikaty są prowadzone przez dwa staże.

• Review: 1; Review 1; FLT: 0 Supports 3; FLT: 0 Supporteus 3; Stage 1 (Documentation Review): Supports 1; FLT: 1 Supporte3; FLT: 0 Supporteur review the technical documentation package to ensure all examplid procedures are in place and teoretically compleant. This is often perfomed off- site or in a meeting rootem thee facility. Non- conformities found her must be resolved before Stage 2.
• Review 1; FLT: 1; FLT: 0 is 3; FLT: 0 is 3; FLT: 0 is 3; Stage 2 (Implementation Verification): 1; FLT: 1 is 3; FLT: 1 is; FLT: 0 is 3; FLT: 0 is 3; FLT: 0 is visits the facility to verify that the procedures are being followed on thee shop lour. They will witness welding, check traceability marks, review calibration labels, interview welders, and exaspentinon controps. The auditor is looking for providence that thee FPPPPPPF embded into dails.

Step 5: Certification and Ongoing Surveillance

Upon successful of Stage 2, thee NB issues thee EN 1090 certificate of conformity, which is valid for a period (often three years). However, certification is note a one- time event. The NB will conduct annual survillance audits to ensure the system continues to functionon effectivelively. In thee the third yes, a full recertification audit is exedirequid. Non- conformities found during survilance cane can tead tsuspension or with drawal of certificate.
