In 2011 the European Commission raised a concern around the legal text supporting presumption of conformity to the Medical Device Directives (Annexes ZA, ZB, ZC) in EN ISO 14971:2009.  The outcome was that CEN decided to publish a new edition of the standard (EN ISO 14971:2012).

This standard has a revised Foreword and Annexes ZA, ZB and ZC, but the core text remains unchanged.

What is BS EN ISO 14971:2012?

BS EN ISO 14971 is a key standard specifying a process for a manufacturer to identify the hazards associated with medical devices, including in vitro diagnostic (IVD) medical devices, to estimate and evaluate the associated risks, to control these risks, and to monitor the effectiveness of the controls.  The requirements of this standard are applicable to all stages of the life-cycle of a medical device.

It does not apply to clinical decision making, does not specify acceptable risk levels and does not require that the manufacturer have a quality management system in place. However, risk management can be an integral part of a quality management system.

How does it work?

BS EN ISO 14971 was developed specifically for medical device/system manufacturers using established principles of risk management. For other manufacturers, e.g., in other healthcare industries, this standard could be used as informative guidance in developing and maintaining a risk management system and process.

It deals with processes for managing risks, primarily to the patient, but also to the operator, other persons, other equipment and the environment. As a general concept, activities in which an individual, organization or government is involved can expose those or other stakeholders to hazards which can cause loss of or damage to something they value. Risk management is a complex subject because each stakeholder places a different value on the probability of harm occurring and its severity.

Claudia's Notes:
The BS EN ISO 14971 is the Official English Language Edition of the EN ISO 14971 standard (European adoption of ISO 14971).  The new 2012 Edition does have changes to the Annexes, describing how the standard does (or does not) meet the requirements of various EU Directives.  If you use the EN edition of the ISO 14971, you'll want to be sure you're using the latest edition.  These changes to the Annexes will impact your business.
