Steam Quality – Non-Condensable Gases (EN 285)
The process of sterilization in medical device manufacturing is critical to ensuring product safety and efficacy. Steam quality, particularly the presence of non-condensable gases (NCGs), plays a pivotal role in the effectiveness of this sterilization process. This service focuses on validating steam parameters as per EN 285, which specifies the conditions for the production and use of steam for medical device sterilization. In this section, we will explore what non-condensable gases are, their impact on sterilization efficacy, the standards that govern them, and how our testing service ensures compliance.
Non-condensable gases in steam can significantly affect the sterilization process by reducing its efficiency or even rendering it ineffective. These gases interfere with the heat transfer necessary for achieving a sufficient temperature gradient within the packaged products to ensure complete microbial destruction. The presence of NCGs also affects the condensation phase, which is essential for maintaining an effective and consistent temperature throughout the sterilization cycle.
The testing procedure according to EN 285 involves several steps: sampling steam at various points in the sterilizer, analyzing the samples using gas chromatography (GC), and comparing the results against predefined acceptance criteria. The key parameters measured include water vapor content, oxygen concentration, carbon dioxide levels, and any other NCGs present.
Our team of experts uses state-of-the-art GC equipment to ensure precise measurements and accurate reporting. This service is crucial for quality managers, compliance officers, R&D engineers, and procurement teams who need to verify that their sterilization processes meet regulatory requirements and maintain product integrity.
The importance of this test cannot be overstated in the medical device sector. Compliance with EN 285 ensures that devices are safe for use and effective against contaminants. This testing is also essential for maintaining trust with healthcare providers and patients, as it guarantees the reliability and safety of sterilized products.
Applied Standards
| Standard | Description |
|---|---|
| EN 285:2019 | This European standard provides requirements for the production and use of steam for medical device sterilization. It specifies conditions to ensure that NCGs do not exceed specified limits, thereby maintaining effective sterilization. |
| ASTM E736-18 | An American standard that complements EN 285 by providing additional guidance on the analysis of steam quality parameters in medical device sterilization processes. |
| ISO 11135:2014 | This international standard outlines a procedure for determining the effectiveness of ethylene oxide gas sterilization, which is often used alongside steam sterilization to ensure comprehensive microbial destruction. |
The combination of these standards provides a robust framework for ensuring that medical device manufacturers adhere to best practices in sterilization. Our laboratory adheres strictly to these standards to provide reliable and accurate testing results.
