A Guide to ISO 13485

16 February 2017
The ISO 13485 standard governs quality management for medical devices and related services. It’s published by the International Organization for Standardization. 

ISO 13485 standard
What is ISO 13485?

The ISO 13485 standard governs quality management for medical devices and related services. It’s published by the International Organization for Standardization. ISO 13485 addresses:

  • Quality control
  •  Risk management
  • Legal compliance
  • Operational efficiency
  • Ability to trace and recall products and devices
  • Process and product improvement

The most recent update to the standard was published in February of 2016, overriding previously published versions from 2003 and 1996. ISO 13485 derived from ISO 9001, a quality management certification that’s available to businesses in a wide variety of industries. However, medical device and pharmaceutical companies have specialized requirements that made some of the requirements of ISO 9001 difficult to apply. ISO 13485 was developed to address these needs.

ISO 13485 provides a great advantage for organizations producing medical devices and related services. It assures a commitment to quality and increases efficiencies within the organization. Becoming ISO 13485 certified can increase client base and reduce barriers to entry of foreign markets, product liabilities, and production down-time.

As the transition period from ISO 13485:2003 to ISO 13485:2016 has begun, it is important for organizations to understand the advantages of becoming ISO certified, identify the key differences between the 2003 publication and the 2016 publication, and begin the work for either transition or first time certification.

The auditing process can appear overwhelming, but it does not have to be. For those seeking their first ISO 13485 certification or those transitioning from the 2003 publication to the 2016 update, the following information can serve as a starting place for implementation. 

Key differences in ISO 13485 (from ISO 9001)

  • Additional requirements for preventing contamination
  • Monitoring focuses on meeting customer requirements, rather than on subjective customer satisfaction measures
  • Multiple documentation requirements at all stages of product development
  • Focus on maintaining the effectiveness of the quality management system instead of continuous improvement (as required for ISO 9001)
  • Risk management during design and production
  • Additional requirements for regulatory reporting, advisory notices, and recalls

Applications of ISO 13485

ISO 13485 specifies quality management for medical device manufacturers and related organizations. This means a variety of companies in the medical device industry and pharmaceutical supply chain use ISO 13485 standards. Organizations that use this standard include:

  • Manufacturers of medical devices
  • Organizations that supply products or raw materials to medical device manufacturers
  • Quality management organizations that contract to medical device manufacturers
  • Organizations that provide services to medical device manufacturers
  • Makers of sterile medical devices
  • Manufacturers of surgical medical devices

A significant change in the 2016 update addresses outsourcing. This update organization requires the organization to ensure that companies it contracts with meet ISO 13485 standards when outsourcing the development, design, or servicing of a medical device.

ISO standards are voluntary, so being certified as ISO 13485 compliant isn’t always necessary. Europe and Japan offer alternative national standards. On the other hand, Canada requires class I, II and III medical device manufacturers to achieve ISO 13485 certification.
medical device approval

Although certification isn’t required, it can provide an advantage. Many countries base their regulatory standards for medical devices on this standard. Achieving either ISO 13485 or ISO 9001 certification is seen as the first step to approval for a medical device in Europe.

Reasons for the 2016 Update

When the 2003 standard was reviewed, ISO staff discussed potential revisions with a variety of regulatory bodies. The consensus was that the old standard no longer reflected current quality management needs.

According to Eamonn Hoxey, former chair of ISO’s technical committee for quality management:

"When we did the last review, we had discussions with the regulatory authorities and we — both industry and the authorities — felt that it was time to revise the standard … Since 2003, a number of jurisdictions have either revised or introduced regulations for medical devices, so we want to make sure the quality management system requirements align fully with those regulatory requirements."

The requirements  within ISO 13485 have been adopted into a number of different countries’ regulatory programs.  Regulators in Australia, Canada, the European Union, Japan, and the United States use it. It is used with modifications in the United Kingdom and by the Medical Device Single Audit Program.

Many of the revisions made to ISO 13485 reflect its importance to regulatory bodies. Among these revisions are: 

  • Increased alignment with regulatory requirements
  • Adjustment of software standards for measurement and reporting
  • Additional requirements for verification and validation planning
  • Increased emphasis on addressing consumer complaints
  • Additional requirements for reporting to regulatory authorities

These revisions are expected to ensure that ISO 13485:2016 aligns more fully with regulatory requirements for medical devices while still making certain that ISO 13485 includes quality management requirements from the ISO 9001 standard.

What is the window to transition to ISO 13485:2016?

The International Organization for Standardization (ISO) published the ISO 13485:2016 update in February 2016. There is a three-year transition period for this standard. During this transition period, organizations may have either ISO 13485:2003 or ISO 13485:2016 certification.
iso 13485:2003

The 2003 version of this standard will be withdrawn in February 2019. After this date, any existing certifications of ISO 13485:2003 will no longer be valid.

During the first two years of the transitional period, it is possible for organizations to become certified under either the 2003 or 2016 versions of these standards. In the third year, however, organizations will only be able to become certified under the 2016 version of ISO 13485.

 Major Revisions in the ISO 13485:2016 Update

major changes to iso 13485

What if your organization is already certified under the 2003 version of ISO 13485? What changes will you need to make in the next few years? To help you get started, we’ve outlined the changes made in the 2016 update below. You’ll find a brief overview of each component of ISO 13485 below, followed by a list of any major changes made to the section in question.

Introduction

The introduction to ISO 13485 provides additional understanding and clarification of terms. Major changes in the introduction include expanded definitions of product life cycles, organizations that this standard applies to, and an understanding of the process approach used by organizations certified under this standard.


0.1    – General

  • Provides more detail about what types of organizations ISO 13485 applies to and what stages of the product life cycle this standard applies to
  • Expands the list of organizations that this standard can apply to:
    • Suppliers of medical devices
    • Third-party organizations providing raw materials, subassemblies, components, and medical devices for the manufacture of these products
    • Organizations offering sterilisation services, calibration services, distribution services and maintenance services for medical device companies
  • Reminds organizations to identify applicable regulatory requirements
  • Clarifies that quality management systems need to meet regulatory requirements as well as those of ISO 13485
  • Expands upon the factors that can influence the development of quality management programs within organizations


0.2 – Clarification of Concepts

  • Adds the following to the conditions needed to define “appropriate requirements.” The new definition of appropriate requirements includes those that are necessary for:
    • The product to meet requirements
    • Compliance with applicable regulatory standards (new requirement)
    • The organization to carry out corrective action
    • The organization to manage risks (new requirement)
  • Explains that “risk” for medical products applies to safety, performance standards, or the necessity to meet regulatory requirements
  • Clarifies that documented requirements also need to be established, implemented, and maintained


0.3 – Process Approach

  • Expands upon the definition of a process approach for medical devices
  • A process approach emphasises:
    • Understanding and meeting requirements
    • Considering the added value of processes
    • Obtaining results of process performance
    • Improving processes based on objective measurements


0.4 – Relationship with ISO 9001

  • Clarifies that sections of this standard based on ISO 9001 refer to the new ISO 9001:2015, and not the previous versions

1 - Scope

iso 13485 clause 1

This section clarifies the organizations and processes that ISO 13485 applies to:

  • Clarifies that ISO 13485 applies to organizations involved in different stages of the life cycle of medical products, including the design, repair, installation, maintenance, and storage of medical devices
  • Expands the standard to include organizations that provide technical support, quality management services, and product support for medical devices
  • Clarifies responsibility for third-party vendors and supplies. States those services and products that are not created by the organization, but are used in its products, are the responsibility of the organization. The certified organization is liable for maintaining, monitoring, and controlling these processes.
  • Explains that the standards in clauses 6, 7, and 8 that are not applicable to the organization can be excluded. This change may be applicable to some suppliers, support organizations, and quality management service suppliers. During certification, the reasons for these exclusions still need to be documented.

2 – Normative References

Clause 2 clarifies that any references to ISO 9000 refer to ISO 9000:2015, and not to ISO 9000:2000 (used by the 2003 version).

3 – Definitions

iso 13485 clause 3

Clause 3 defines terms used throughout this update to ISO 13485.

  • Modifies certain definitions
    • Modified definitions focus on defining medical devices and products. This definition is significantly more detailed than that found in the previous version of this standard. Implantable medical devices and sterile medical devices both get new definitions as well.
  • Adds additional definitions
    • Added definitions focus on defining roles within the life cycle of product development, including defining distributors, importers and manufacturers. Adds definitions of risk, risk management, performance evaluation, and post-market surveillance.

4 – Quality Management System

Clause 4 addresses the requirement to document procedures relating to the quality management process. Documentation requirements have been expanded and clarified in the 2016 update. There is additional language that clarifies that quality management processes required by ISO 13485 do not exempt an organization from meeting any additional quality management requirements mandated by regulatory authorities. A primary change here states that quality management requirements now apply to any outsourced products as well as those produced by the organization itself.


4.1 – General Requirements

  • States that the organization is responsible for establishing, implementing and maintaining any quality management processes required by this standard
  • Explains that ISO 13485 certification does not exempt the organization from other applicable regulations. The organization is also required to establish, implement and maintain processes required by other regulatory bodies. The requirement to meet other applicable regulatory requirements is emphasised throughout this version.
  • Clarifies that organizations must use a risk-based approach in their quality management processes
  • Explains that an organization is responsible for monitoring any outsourced processes. This is a considerable change from the 2003 version of this standard. Any outsourced processes still need to conform to the quality management standards of the medical device organization, and written quality agreements with the third party must be in place.


4.2 – Documentation Requirements

  • Documentation requirements have been considerably expanded. With the exception of the medical device file, all documents were required by the previous standard. However, the additional details of what this documentation must include have been clarified.
  • The Quality Manual now requires an explanation of the scope of the project management system, as well as justifications for any exclusions from it
  • Requires the development of a medical device file for each product, which must include specifications, labelling, use instructions, and any requirements for installation and servicing
  • Many of the requirements for document control remain the same. Documents are required to be reviewed and approved before publication. Records and documents applicable to medical devices still need to be kept for at least the lifetime of the medical device.

5 – Management Responsibility

ISO 13485 clause 5
Clause 5 addresses the management responsibilities for maintaining, documenting, and reviewing procedures. This section has undergone relatively minor changes in the 2016 update. Most of the changes in this section focus on management review.


5.6 – Management Review
  • Organizations are required to have and use documented procedures for reviews
  • Management review has been expanded to include complaint handling and reports to regulatory authorities
  • Organizations must now record any output from management reviews
  • The list of review outputs has been expanded. It now includes decisions and actions related to resource needs and to improvements needed to maintain the quality and suitability of the QMS system.

6 – Resource Management

This section covers requirements for a variety of types of resource management: human resources, infrastructure, work environment, and contamination control. This section, or clauses within it, may not be applicable to all organizations that are seeking ISO 13485 certification. Organizations that believe components of this section are not relevant can also submit an explanation that justifies their exclusion.


6.2 – Human Resources

  • Changes in this section focus on requirements for additional documentation of the processes for establishing competency
  • The updates include the ability to use processes proportional to the risk level of the action. Low-risk tasks may require very little documentation to prove competency, while high-risk actions require considerably more.


6.3 – Infrastructure

  • Language has been added to state that it is important to ensure the proper handling of product and that protocols must be in place to prevent product mix-up
  • Required documentation for maintenance activities has been expanded. Maintenance requirements must now be documented for maintenance activities, equipment used in production, work environment controls, and monitoring and measurement systems.


6.4 – Work Environment

  • An additional clause has been added to state that documentation of protocols for maintaining the work environment is required when the state of the work environment could have an impact on the quality of the product.
  • An additional section (6.4.2) has been added to address contamination controls.
  • If product contamination is a concern, the organization must plan and document the procedure for controlling contaminated products.

7 – Product Realisation

product realisation

This section addresses the processes the organization uses during product development. The bulk of changes in the 2016 update occur within Clause 7.

The Benefits of Implementing ISO 13485:2016

attract more clients
Businesses that have implemented ISO 13485 cite numerous benefits. Many companies seek the certification because of the financial benefits to their business. The certification demonstrates their commitment to building high-quality medical devices. That allows businesses to attract more clients than before.

Additional of the other benefits include:

1.    Ability to Contract with Larger Companies

Many large medical device businesses prefer to work with vendors who are ISO 13485 certified. The 2016 update to this standard may make this even more desirable. The revisions mean that large companies are responsible for ensuring that any subcontractors conform to ISO 13485 standards. That means subcontractors who already have the certification are likely to be prioritized.

2.    Demonstrate Commitment to High Quality

Both ISO 13485 and ISO 9001 are seen as indicators of an organization’s commitment to quality. Achieving a quality management certification demonstrates to customers and regulators that your company values quality.

3.    Expand Potential Market

Standards like ISO 13485 are created to ensure that medical devices in different places demonstrate the same reliability and quality. If you’re considering exporting products, ISO 13485 certification can lend an advantage. Not only is it the first step to regulatory approval in major markets like the European Union and Canada, but it also demonstrates the quality of the product to potential buyers.

4.    Help Personnel Access Relevant Information

The documentation requirements in this standard are designed to ensure that all members of a development team have access to the information they need, when they need it. Having access to the right information can reduce the time and expense associated with product development.

5.    Expand and Consolidate Business Knowledge

We also hear from clients that documenting the processes associated with their medical device helps the business develop a consolidated knowledge base. This knowledge can help to identify problems, improve the product, and streamline the manufacturing process. It also makes the process of on-boarding new employees easier.

6.    Make Achieving ISO 9001 Certification Easier

Many businesses hold both ISO 13485 and ISO 9001 certifications. If your business is ISO 13485 certified, achieving ISO 9001 certification is significantly easier. The requirements of these two standards are generally harmonised. ISO 9001 does contain a few requirements related to business clauses that ISO 13485 doesn’t cover.

Getting Certified for ISO 13485

getting certified
Getting certified for an ISO standard can be a difficult process. Preparation and good organization can make it less stressful.

Understanding the requirements of ISO 13485 is a good place to start. Your auditor will be referring to these standards as they evaluate your organization. Documenting and organising your quality management procedures is another important step.

Next, make sure employees as well as management know the organization’s quality management processes. Keeping everybody on the same page will help the audit process go smoothly.

It is often required to conduct an internal audit before conducting the external audit for certification. An internal audit can help you determine whether any changes need to be made to your quality management system before certification.

It’s also important to choose the right auditor to conduct the audit. Since an audit is fundamentally an on-site verification of your quality management processes, look for an auditor with a local presence. This can speed up the auditing process and reduce problems that arise from language or cultural barriers.

Your auditor should also be experienced. For instance, NQA has conducted more than 35,000 certifications in 70 different countries. This means that, when questions about logistics or the audit process arise, our experienced auditors can help you find the answer.

When NQA audits a business, we work with your processes and procedures. That means you won’t be required to add processes that don’t work for your business. Dedicated Customer Service representatives will ensure that you have feedback throughout the registration process so that you can address questions that arise during the auditing process quickly, and get back to work sooner.
