  • This standard applies to various stages of a medical device’s life cycle, including design and development, production, storage, distribution, installation, and servicing.

  • It also encompasses associated activities, such as technical support.


  • ISO 13485:2016 is relevant to organizations of all sizes and types, except where explicitly stated otherwise.

  • When requirements are specified for medical devices, they equally apply to associated services provided by the organization.

ISO 14971

Purpose and Scope

  • ISO 14971 provides a structured approach to identify, assess, and manage risks associated with medical devices.

  • It encompasses not only physical devices but also software used in healthcare and in vitro diagnostic devices.

  • The primary objectives are to enhance patient safety, minimize adverse events, and ensure the effectiveness of risk control measures.


  • The requirements outlined in ISO 14971 apply to all phases of a medical device’s life cycle. Whether during design, production, distribution, or post-market surveillance, risk management remains paramount.

  • The standard addresses a wide spectrum of risks, including those related to biocompatibility, data security, electricity, moving parts, radiation, and usability.

  • It extends its reach to products that may not strictly qualify as medical devices in certain jurisdictions. However, it does not cover clinical procedure decisions or broader business risk management.

ISO 62304:2006

Purpose and Scope

  • ISO 62304:2006 defines the life cycle requirements for medical device software.

  • It establishes a common framework for managing the software life cycle processes in the context of medical devices.

  • The standard encompasses the development and maintenance of software that either constitutes a medical device itself or serves as an embedded/integral part of the final medical device.


This standard applies when:

  • software is a standalone medical device;

  • software is an embedded component within a medical device;

  • software is used in the production of a medical device;

  • software is the device itself (such as Software as a Medical Device or SaMD).

FDA Regulations for Medical Devices

Purpose & Scope:

  • The FDA classifies medical devices into three categories: Class I, II, and III. The classification regulation defines the requirements for each device type. Most Class I devices are exempt from Premarket Notification 510(k); most Class II devices require Premarket Notification 510(k); and most Class III devices necessitate Premarket Approval.

  • Manufacturers (both domestic and foreign) and initial distributors (importers) of medical devices must register their establishments with the FDA. This includes various entities such as contract producers, sterilizers, repackagers, and developers of accessories. Even U.S. manufacturers of “export only” devices fall under this requirement.

  • If your device requires 510(k) submission, commercial distribution is contingent upon receiving FDA authorization.

  • Adherence to quality system requirements ensures consistent product quality. Manufacturers must follow current good manufacturing practices (CGMP).

  • Producers must promptly report adverse events related to their devices. This reporting system helps monitor safety and effectiveness.


  • Compliance with FDA standards is often viewed as essential for most markets worldwide. It ensures alignment with international safety norms.

  • While the FDA ensures safety, it doesn’t guarantee device effectiveness. Evidence of effectiveness is required for premarket approval.

IEC 60601

Purpose and Scope

  • The IEC 60601 series of technical standards is a beacon for ensuring the safety and essential performance of medical electrical equipment.

  • The cornerstone of this series is IEC 60601-1, aptly titled Medical Electrical Equipment – Part 1: General Requirements for Basic Safety and Essential Performance. It lays down fundamental safety principles applicable to all medical electrical devices. Compliance with this standard has become a prerequisite for commercializing electrical medical equipment in numerous countries.

  • Within the IEC 60601 series, certain terms are capitalized, signifying their specific definitions. For instance, ME EQUIPMENT refers to equipment intended for diagnosis, treatment, monitoring, or disease alleviation. It may have up to one power connection and can be battery-operated. Additionally, APPLIED PARTS are components that come into physical contact with the patient during normal use.


  • IEC 60601-1 serves as a widely accepted benchmark for medical electrical equipment. Companies often view compliance with this standard as essential for most markets.

  • While IEC 60601-1 ensures safety, it doesn’t guarantee the effectiveness of a medical device. In the US, the FDA requires evidence of effectiveness through premarket approval or similarity to a predicate device.

  • The IEC 60601 series includes collateral and particular standards. These may override or modify requirements based on specific product types.

Importance of Compliance

Compliance with these standards is critical for several reasons:

  1. Patient Safety: Standards ensure that medical devices meet safety and efficacy requirements, minimizing risks to patients.

  2. Market Access: Regulatory bodies often require compliance for market approval. Without it, manufacturers may face barriers to entry.

  3. Quality Assurance: A robust QMS enhances product quality, reduces defects, and fosters customer trust.

  4. Legal and Financial Implications: Non-compliance can lead to legal penalties, recalls, and reputational damage.
