There is also a limit on the acceptable calibration period and the expiration of the calibration period needs to be on the sticker placed on the instrument. Extend the period and take your chance. lol.
This was actually the topic of our discussions.
ISO/IEC 17025, Paragraph 5.10.4.4 - A calibration certificate (or calibration label) shall not contain any recommendations on the calibration interval except where this has been agreed by the customer. This requirement may be superseded by legal regulations.
Re-calibration intervals are to be determined statically or by experience, thus the demand that the calibration houses do not assign and or imply calibration intervals.
In my case, a customer brought up the question of how often should they have the samples re-certificated. My answer was "never" unless physically damaged.
Their QA department didn't like that. I told them every 30 days. They didn't like that. Asked them what did they want to hear? They couldn't answer that either.
In reality, we've never adjusted a sample value (in the past 20+ years) unless the sample was visually damaged or destroyed.
They decided on once a year when I left. They are now up to once every 5 years the last I heard.
