By adhering to ISO 14644, companies can ensure that their controlled environments minimize the risk of contamination, thus protecting the integrity of products and processes crucial in medical device manufacturing. Can ISO 13485 and ISO 14644 Audits Be Conducted Simultaneously? Yes, ISO 13485 and ISO 14644 audits can indeed be conducted simultaneously, and doing so offers several advantages for both the auditing body and the supplier. This combined approach not only saves time and resources but also provides a more comprehensive overview of a supplier’s operations and their adherence to critical standards in medical device manufacturing. Integrated Approach Conducting these audits simultaneously involves an integrated approach where auditors assess the quality management system and the environmental controls within the same audit timeframe. Efficiency Simultaneous audits are more efficient as they reduce the need for multiple audit sessions, which can be costly and time-consuming, especially when suppliers are located across different geographical locations. Comprehensive Assessment Auditors can more effectively identify any interconnected issues between the quality management system and the environmental conditions. For example, a problem in the cleanroom air quality (ISO 14644) could directly affect the quality control processes (ISO 13485), impacting product sterility. Why Combining ISO 13485 and ISO 14644? While ISO 13485 includes certain clauses that address cleanroom requirements, it does not delve as deeply into specifics as ISO 14644. ISO 13485 primarily focuses on broader quality management systems and processes, ensuring that medical devices are consistently produced and controlled according to regulatory requirements. However, it touches on general cleanroom standards, notably in Clause 6, which deals with "Production and Service Provision." This clause includes requirements for controlling production environments that affect product quality, mentioning aspects like contamination control which are critical for cleanrooms. In contrast to ISO 16444, ISO 13485 does not offer detailed specifications for achieving and maintaining the required air purity, particle counts, or effectively monitoring and controlling the environment. ISO 14644 specifically addresses the classification of air cleanliness, the methodologies for testing and monitoring cleanrooms, and the operational protocols needed to maintain the necessary cleanliness levels over time. For certain types of medical devices, especially those requiring sterile manufacturing environments, the specifics provided by ISO 14644 are essential. These standards ensure that the controlled environments are suitable for producing high-risk devices, helping to prevent contamination that could compromise the safety and effectiveness of a product. Preparation for a Combined Audit Preparing for a combined audit that incorporates both ISO 13485 and ISO 14644 standards is a meticulous process that requires careful planning and coordination.
