ISA 95
International standard for enterprise-manufacturing control integration
EN 1090
EU standard for steel and aluminium structural execution
Quick Verdict
ISA 95 provides semantic models for global manufacturing IT/OT integration, while EN 1090 mandates CE marking and FPC for EU structural steel/aluminium fabrication. Companies adopt ISA 95 for efficient operations; EN 1090 for legal market access.
ISA 95

- Provides activity models for manufacturing operations management
- Specifies transactions for business-to-manufacturing exchanges
- Enables alias services for multi-system identifier mapping
EN 1090
EN 1090 Execution of steel and aluminium structures
Key Features
- Factory Production Control (FPC) certification by Notified Body
- Execution Classes (EXC1-4) for risk-based requirements
- Mandatory CE marking under CPR for market access
- Welding quality management via ISO 3834 alignment
- Full material and process traceability mandates

ISA 95 Details
What It Is
ANSI/ISA-95 (IEC 62264), a technology-agnostic framework, defines integration between enterprise business systems like ERP and manufacturing operations systems like MES. Its primary purpose is reducing integration risks, costs, and errors via semantic models and standardized interfaces, focusing on the Level 3-4 boundary in the Purdue model.
Key Components
- Hierarchical Levels 0-4 model organizing activities and boundaries.
- **Eight partsmodels/terminology (Part 1), objects/attributes (Parts 2/4), activities (Part 3), transactions (Part 5), messaging/aliasing/profiles (Parts 6-8).
- Core principles: equipment hierarchy, consistent object semantics for materials/equipment/personnel/production.
- No formal product certification; compliance via architectural alignment and training programs.
Why Organizations Use It
Drives semantic consistency, faster integrations, and data governance. Enables OEE improvements, traceability, and IT/OT collaboration. Reduces reconciliation errors; supports regulatory audits and cybersecurity segmentation. Builds stakeholder trust through shared vocabulary and scalable architectures.
Implementation Overview
Phased approach: governance, gap analysis, canonical modeling, pilots, rollouts. Applies to manufacturing firms globally; involves cross-functional teams, master data management. Emphasizes security (IEC 62443 alignment); no mandatory audits but self-assessed conformance.
EN 1090 Details
What It Is
EN 1090 is a harmonized European standard family for the execution of steel and aluminium structural components. It serves as the primary framework under the EU Construction Products Regulation (CPR) for CE marking of load-bearing metal components in construction. Its risk-based approach scales requirements via Execution Classes (EXC1–EXC4) based on consequence, service, and production categories.
Key Components
- **EN 1090-1Conformity assessment, Factory Production Control (FPC), and Declaration of Performance (DoP).
- **EN 1090-2/-3Technical rules for steel/aluminium execution (welding, tolerances, corrosion protection, inspection).
- Core principles: traceability, welding coordination (ISO 3834), NDT inspection.
- **Certification modelNotified Body audits FPC with ongoing surveillance.
Why Organizations Use It
- Mandatory CE marking for EU market access.
- Reduces liability, rework, and ensures structural safety.
- Builds trust with clients, enables high-risk projects.
Implementation Overview
Phased: gap analysis, FPC development, personnel training, NB certification. Applies to fabricators in EU/EEA; 3-12 months typical, with audits.
