Free guide to IEC 62353

An introduction to electrical safety testing in accordance with IEC 62353

This booklet is written as a guideline for people involved in testing medical electrical equipment (ME equipment).

The aim of this booklet is to help the reader to:

  • Appreciate the basics of electrical safety.
  • Understand the reasons behind and the purpose of the IEC 62353 publication.
  • Provide an understanding of the benefits of using the different tests available, in order to help them prepare the adoption of the IEC 62353 standard.
The healthcare market is technology driven and with a global demand for increased patient safety, there has never been a more prudent time to demand more from your test equipment.

International standards for the development and manufacturing of medical devices put greater emphasis on risk assessment and analyses of data. So, there is an increased need for test equipment that allows the user to automate data capture and ensure validity of test results for better management of risk.
