Overview

BS EN 55011 Fragments 2-7 outlines the radio-frequency disturbance characteristics for industrial, scientific, and medical (ISM) equipment. This standard is essential for manufacturers and operators of wireless power transfer (WPT) systems, particularly those employing air-gap technology. The standard specifies limits and methods of measurement to ensure compliance with electromagnetic compatibility (EMC) requirements.

Key Requirements

The standard establishes specific limits for radiated and conducted emissions from ISM equipment. Key requirements include:

• Emission Limits: Defines acceptable levels of electromagnetic interference (EMI) that equipment can emit.
• Measurement Methods: Provides detailed procedures for testing equipment to ensure compliance with emission limits.
• Equipment Classification: Categorises equipment based on its intended use and operational environment.
• Air-Gap WPT Specifications: Outlines unique requirements for systems that transfer power wirelessly across an air gap.

Implementation Benefits

Adhering to BS EN 55011 Fragments 2-7 offers several practical benefits for manufacturers and users of ISM equipment:

• Enhanced Product Reliability: Compliance with the standard ensures that products operate without causing undue interference to other electronic devices.
• Market Access: Meeting the standard is often a prerequisite for entering specific markets, particularly in Europe.
• Consumer Confidence: Products that comply with recognised standards are more likely to gain consumer trust, leading to increased sales.
• Reduced Risk of Non-Compliance: Following the standard mitigates the risk of penalties or product recalls due to non-compliance with EMC regulations.

Compliance Value

Compliance with BS EN 55011 Fragments 2-7 is crucial for ensuring that ISM equipment operates within acceptable electromagnetic limits. This not only protects the integrity of the equipment but also safeguards the performance of surrounding devices. Furthermore, compliance can facilitate smoother regulatory approvals and reduce the likelihood of disputes related to electromagnetic interference.

In summary, BS EN 55011 Fragments 2-7 provides a comprehensive framework for managing radio-frequency disturbances from ISM equipment. By adhering to this standard, manufacturers can enhance product performance, ensure market readiness, and foster consumer trust.
