CE Marking
EU marking for product conformity to harmonised legislation
ISA 95
International standard for enterprise-manufacturing system integration.
Quick Verdict
CE Marking mandates EU product safety compliance for market access, while ISA 95 provides voluntary integration models linking enterprise and manufacturing systems. Companies adopt CE for legal EEA sales; ISA 95 to reduce IT/OT integration costs and errors.

CE Marking Details
What It Is
CE Marking (Conformité Européenne) is the EU's primary product compliance marking under harmonised legislation like the New Legislative Framework (NLF). It serves as a manufacturer's declaration that products meet essential health, safety, and environmental requirements. Scope covers categories such as electrical equipment, machinery, and medical devices. Key approach is risk-proportionate, using harmonised standards published in the OJEU for presumption of conformity.
Key Components
- Essential requirements from specific directives/regulations (e.g., LVD 2014/35/EU).
- Conformity assessment modules (A-H), self-assessment or Notified Body involvement.
- Technical file, EU Declaration of Conformity (DoC), and CE mark affixing.
- Post-market surveillance under Regulation (EU) 2019/1020. Compliance model is manufacturer-led, with no central EU certification.
Why Organizations Use It
Mandated for EEA market access, enabling free movement. Reduces trade barriers, ensures legal compliance, manages liability risks, and builds stakeholder trust. Provides competitive edge via standardized safety assurance.
Implementation Overview
Involves legislation mapping, risk assessment, testing, documentation compilation, DoC issuance, and marking. Applies to manufacturers/importers across industries and sizes; Notified Body audits for high-risk products. Focus on SMEs and globals entering EU market.
ISA 95 Details
What It Is
ISA-95 (ANSI/ISA-95, IEC 62264) is an international reference architecture and information model standard for integrating enterprise business systems (Level 4, e.g., ERP) with manufacturing operations (Level 3, e.g., MES). Its primary purpose is reducing integration risks, costs, and errors through semantic consistency across the enterprise-control boundary, using a Purdue hierarchy-based approach with activity, object, and exchange models.
Key Components
- Eight parts covering models/terminology (Part 1), objects/attributes (Parts 2/4), activities (Part 3), transactions (Part 5), messaging/alias services (Parts 6-7), and profiles (Part 8).
- Core Purdue levels 0-4 and equipment hierarchy.
- No formal certification; compliance via architectural alignment and training programs.
Why Organizations Use It
- Drives semantic interoperability, operational agility, and data governance.
- Enables OEE improvements, traceability, and IT/OT collaboration.
- Supports Industry 4.0, cybersecurity segmentation, and regulatory audits.
- Builds stakeholder trust through consistent KPIs and reduced errors.
Implementation Overview
- Phased: assessment, canonical modeling, pilot, rollout, governance.
- Applies to manufacturing firms globally; involves workshops, data mapping, secure interfaces.
- No mandatory audits; focuses on internal governance and vendor alignment. (178 words)
