ISA 95
International standard integrating enterprise and manufacturing control systems
AS9120B
Aerospace QMS standard for parts distributors
Quick Verdict
ISA-95 provides integration models for manufacturing enterprises, while AS9120B mandates QMS certification for aerospace distributors. ISA-95 reduces IT/OT ambiguity voluntarily; AS9120B ensures traceability and counterfeit prevention, often required for supply chain access.

ISA 95 Details
What It Is
ANSI/ISA-95 (IEC 62264) is a technology-agnostic framework for integrating enterprise business systems like ERP with manufacturing operations systems like MES. Its primary scope is the Level 3-4 interface in the Purdue model, using hierarchical levels, activity models, and object semantics to standardize information exchanges and reduce integration risks.
Key Components
- Eight parts: models/terminology (Part 1), objects/attributes (Parts 2/4), activities (Part 3), transactions (Part 5), messaging/aliasing/profiles (Parts 6-8).
- Purdue levels 0-4 organizing processes from physical production to business planning.
- Core principles: shared vocabulary, consistent data models for equipment, materials, personnel.
- No formal product certification; compliance via architectural alignment and training programs.
Why Organizations Use It
Drives IT/OT collaboration, cuts integration costs/errors, enables traceability/OEE. Supports regulatory audits, Industry 4.0, cybersecurity segmentation. Builds stakeholder trust through auditable, scalable architectures and competitive agility in manufacturing.
Implementation Overview
Phased approach: assess gaps, define canonical models, pilot transactions, rollout with governance. Applies to manufacturing firms globally; requires cross-functional teams, data stewardship, security (IEC 62443). No mandatory audits; focus on semantic governance and testing. (178 words)
AS9120B Details
What It Is
AS9120B is the IAQG quality management system standard for aerospace distributors, built on ISO 9001:2015's high-level structure. It establishes requirements for organizations procuring, storing, splitting, and reselling parts without altering characteristics, emphasizing risk-based thinking to mitigate supply chain risks like traceability loss and counterfeits.
Key Components
- Over 100 aerospace-specific additions to ISO 9001 across 10 clauses.
- Core areas: context analysis, leadership, planning, support, operations (traceability, preservation, counterfeit prevention), performance evaluation, improvement.
- Built on PDCA cycle; requires documented information, not a full manual.
- Certification via accredited bodies, listed in IAQG OASIS.
Why Organizations Use It
- Commercial necessity for OEM/Tier-1 supply chains.
- Reduces risks of nonconformities, counterfeits, legal liabilities.
- Enhances efficiency, customer trust, market access (2,442 global certifications).
- Builds competitive edge through robust chain-of-custody.
Implementation Overview
- Phased: gap analysis, process design, training, audits (6-12 months).
- Applies to aviation/space/defense distributors globally.
- Stage 1/2 certification audits; ongoing surveillance.
