Test methods for sterile medical device package
- Part1: Test guide for accelerated aging
1 Scope
1.1 This part of YY/T 0681 provides information for developing accelerated aging protocols to rapidly determine the effects, if any, due to the passage of time and environmental effects on the sterile integrity of packages and the physical properties of their component packaging materials.
1.2 Information obtained using this part may be used to support expiration date claims for product packages.
1.3 The accelerated aging guideline addresses the primary medical package in whole and does not address the package and product interaction or compatibility that may be required for new product development. Package and product compatibility and interactions should be addressed as a material analysis process before package design.
1.4 Real-time aging protocols are not addressed in this part; however, it is essential that real-time aging studies be performed to confirm the accelerated aging test results using the same methods of evaluation.
1.5 Methods used for package process validation, which include the machine process, the effects of the sterilization process, transport and storage, are beyond the scope of this part.
1.6 This part does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this part to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
