ISO 11135:2014 Certification Services – Ethylene Oxide (EtO) Sterilization Management System
What is ISO 11135:2014?
ISO 11135:2014 outlines the requirements for developing, validating, and controlling ethylene oxide (EtO) sterilization processes for medical devices. This standard is applicable to both medical device manufacturers and healthcare facilities. It emphasizes the importance of ensuring microbicidal effectiveness and meeting defined sterile product requirements.
Here’s a more detailed breakdown:
Key Aspects of ISO 11135:2014:
Scope:
The standard specifically addresses EtO sterilization of medical devices, covering development, validation, and routine control of the process.
Applicability:
It applies to both medical device manufacturers and healthcare facilities, acknowledging the differences in their sterilization practices.
Microbicidal Effectiveness:
A core requirement is that the sterilization process must demonstrate adequate microbicidal activity.
Validation:
The standard provides a framework for validating EtO sterilization processes, ensuring they consistently deliver sterile products with a high degree of confidence.
Routine Control:
It also covers the ongoing monitoring and control of the sterilization process to maintain its effectiveness over time.
Beyond Sterilization:
While the standard focuses on the sterilization process itself, it also acknowledges other critical aspects, such as bioburden control, cleaning procedures, and packaging, which contribute to the overall sterility of the product.
In essence, ISO 11135:2014 provides a comprehensive framework for managing the risks associated with EtO sterilization, ensuring that medical devices are safe for patient use.

Steps to Certification
Step 1
Complete a Quote Request Form so we can understand you and your business. We will then use this to personally prepare a proposal for your certification and define what is known as your ‘scope of assessment’.
Step 2
We will then contact you to book your assessment with an NQA assessor. It consists of two mandatory visits that form the Initial Certification Audit. Please note that you must be able to demonstrate that your management system has been operational for a minimum of three months and has been subject to a management review and a full cycle of internal audits.
Step 3
Following a successful stage two audit, a decision is made. If positive, your certification will be issued by NQA, with both a hard and soft copy of the certificate awarded. Certification is valid for three years and maintained through surveillance audits (years one and two) and a recertification audit in year three.
Why choose ISO 11135:2014 ?
- Comprehensive Guidance:The standard offers detailed requirements for all stages of the EtO sterilization process, from development and validation to routine control.
- Ensures Sterility:By following ISO 11135:2014, manufacturers can demonstrate that their sterilization processes are effective in eliminating harmful microorganisms, including bacteria, viruses, fungi, and spores.
- Patient Safety:Sterilization is crucial for preventing infections associated with medical devices. ISO 11135:2014 helps ensure that devices are safe for patient use.
- Regulatory Compliance:ISO 11135:2014 is a globally recognized standard and is often referenced by regulatory bodies like the FDA.
- Material Compatibility:EtO sterilization is often used for heat-sensitive materials, and the standard addresses the compatibility of various materials with the sterilization process.
