For how long must magazine temperature record cards be maintained?

Magazine temperature record cards must be maintained for one year to ensure compliance with regulations governing the storage of ammunition. This timeframe is critical because it provides a sufficient period for monitoring temperature stability in storage locations, which can impact the safety and effectiveness of the ammunition. Keeping records for one year allows for a reliable assessment of the storage environment, helping to ensure that temperatures remain within acceptable limits. After one year, it is generally considered that the data can be discarded unless specific regulatory requirements suggest otherwise.
