What are the requirements for using homemade standards?
Among the standard categories offered by Shanghai Hengyuan, self-made standards have become one of the most popular products. Based on customer feedback and technical requirements, this week’s technical update from Shanghai Hengyuan Biological Company aims to provide a detailed guide on homemade standards. In this article, we will walk you through the usage conditions, best practices, and important precautions for using self-made reference materials. We welcome all our customers and partners to share their experiences and learn together with us.
When conducting tests, it is essential that the self-made standard aligns with the specifications of existing standards. Repeated testing should be performed, and the results should be averaged for accuracy. If the self-made sample meets all required performance criteria, the average value can be clearly marked on the container and stored as a self-made standard. It is recommended to re-validate these standards annually or whenever there are changes in the standard itself to ensure continued reliability and compliance.
1. Ensure that the source of the standard is reliable, and use nationally recognized reference materials that meet the necessary verification requirements.
2. Maintain proper records and manage the storage of standard products according to specified guidelines. Store them under appropriate environmental conditions to preserve their integrity.
3. It is advisable that the supplier of the standard material also provides detailed usage instructions, including shelf life and storage recommendations, to help users maintain quality and consistency.
