Electromagnetic Compatibility Directive 89/336/EEC

Introducing EMC Directive 89/336/EEC – Industrial Physics

Directive 89/336/EEC was the original European Electromagnetic Compatibility (EMC) Directive, establishing essential requirements to ensure that electrical and electronic equipment:

• does not generate electromagnetic disturbance beyond acceptable levels, and
• has adequate immunity to external electromagnetic interference.

It was adopted on 3 May 1989 and later repealed in 2007, replaced by 2004/108/EC.

Despite being superseded, it remains relevant for legacy products, historical compliance, and long‑term documentation.

What EMC Directive 89/336/EEC Covers

The directive harmonized EMC requirements across EU Member States to ensure the free movement of compliant electrical and electronic equipment. Key elements include:

• Limits on electromagnetic emissions from equipment
• Requirements for immunity to electromagnetic disturbances
• CE marking obligations
• Manufacturer documentation and conformity assessment
• Rules for both apparatus and fixed installations

It was amended several times (e.g., 91/263/EEC, 92/31/EEC, 93/68/EEC) to refine CE marking and align with other EU directives.

Why EMC Compliance Matters

Understanding and meeting EMC requirements is essential for:

• Ensuring reliable performance of electrical and electronic equipment
• Preventing interference with nearby devices
• Meeting EU market access and CE marking obligations
• Reducing risks of malfunction, safety issues, and customer complaints
• Supporting long‑term compliance for legacy equipment

EMC compliance remains a foundational requirement for modern electronics, even though the directive has been updated.

8700/8701 OxySense Oxygen Permeability Analyser

The OxySense Oxygen Permeability Analyser provides precise, non‑invasive oxygen measurement for packaging materials and finished products. While not an EMC instrument, it supports broader quality and reliability programs by helping manufacturers validate packaging integrity and product stability.

Key benefits include:

• Optical, non‑consumable oxygen sensing
• Accurate permeability and headspace analysis
• Ideal for films, pouches, bottles, and rigid containers
• Supports R&D, QC, and production environments
