IEC 60601-2-3:1991/AMD1:1998

Overview

IEC 60601-2-3:1991/AMD1:1998 is an important amendment to the international standard IEC 60601-2-3, which specifically addresses medical electrical equipment - particularly the safety requirements for short-wave therapy equipment. Published by the International Electrotechnical Commission (IEC), this amendment incorporates revisions that integrate amendments 1 and 2 of the General Standard IEC 60601-1, emphasizing references to collateral standards. The technical content remains largely unchanged but refines the scope, definitions, and safety requirements for these therapeutic medical devices.

The standard serves as a critical guideline for manufacturers, engineers, healthcare providers, and regulatory bodies involved in the design, production, and utilization of short-wave therapy devices, ensuring the safety of patients and medical personnel.

Key Topics

This amendment introduces several updates and clarifications related to the safety and performance of short-wave therapy equipment:

• Scope Clarification
  Defines the scope and includes subclauses like 1.1 Scope and 1.5 Collateral Standards to clearly delineate the applicability and interrelation with related standards.

• Definition of Low Power Equipment
  Introduces the term Low Power Equipment, defined as equipment with a rated output power not exceeding 10 W, which is exempted from certain requirements.

• Collateral Standards Incorporation
  References essential IEC collateral standards including:

  • IEC 60601-1-1: Safety requirements for medical electrical systems
  • IEC 60601-1-2: Electromagnetic compatibility requirements and tests
  • IEC 60601-1-4: Programmable electrical medical systems

• Labeling and Marking Requirements
  Specifies detailed marking instructions, including output power indications and applied part identification (Types BF, CF), to ensure proper usage and safety.

• Instructions for Use Enhancements
  Updates warnings such as not applying short-wave therapy through clothing or on patients wearing metallic objects, to avoid hazards from electromagnetic interactions.

• Testing and Compliance Procedures
  Refines terminology and methods related to tests on sequence, temperature rise, electromagnetic compatibility (EMC) - especially radiofrequency (RF) emissions - and accuracy of operating data.

• Safety Against Excessive Radiation and Temperature
  Emphasizes protection measures against unwanted or excessive electromagnetic radiation and temperature increases to prevent patient injury or device malfunction.

Applications

The IEC 60601-2-3:1991/AMD1:1998 amendment is applicable for:

• Manufacturers of short-wave therapy machines, helping them meet updated safety criteria and compliance requirements, reducing risk of malfunction or patient harm.
