Determining Calibration Intervals - Extend or change the length of

[RogerV]

ISO 17025 states that calibration laboratories may not include in the Calibration Certificate (or label) any recommendation upon calibration interval unless agreed with the client. As a measurement equipment manufacturer with our own service/calibration labs, we find our customers in general do expect to use the manufacturer's recommended interval and are not prepared to do the work to estimate an interval themselves.
Would we comply with ISO 17025 if we included in the terms and conditions for calibration business that "the customer is deemed to have agreed to the recommendation of calibration interval"?

Roger,

I've found that most manufacturers send a confirmation copy of the purchase order back to us when we order something. Possibly you could put a generic stamp of "Calibration interval will be [x timeframe] unless otherwise requested by the client."

We had enough response from customers to keep their default cycle that I've actually made it a form letter that they sign.

What kind of jerk doesn't give you a handy-dandy link so you can get the thing that he references? Well, me for one, but I can fix my oversight. The link is:
https://www.ncslinternational.org/publications/abstract.cfm?ID=29

Note: It comes with a disk that helps you do the interval test. I like any book that comes with media that simplifies my job, but I'm simple that way.

Looks like they changed their URL to https://ncsli.org

I don't know what document Ryan Wilde referenced, but this is a search for "calibration intervals" on that website https://ncsli.org/search/all.asp?bst=calibration+intervals
