EN 60601-2-44:2009/A11:2011

Overview

EN 60601-2-44:2009/A11:2011 is a critical European standard focusing on medical electrical equipment, specifically outlining the particular requirements for the basic safety and essential performance of X-ray equipment used in computed tomography (CT). Developed and maintained by CLC/TC 62 “Electrical equipment in medical practice,” this amendment A11 updates the 2009 base version to ensure enhanced compliance with current technological and regulatory expectations within the EU medical device framework.

This standard plays a pivotal role in safeguarding both patients and healthcare operators by defining stringent safety measures and performance benchmarks for CT X-ray devices. It also aligns with the European Commission Directive 93/42/EEC on medical devices, contributing to harmonized safety and performance regulations across EU member states.

Key Topics
