7.8.4.1 is a ”shall” statement, which means it is required. I have not been through an audit with the new 2017 standard, but the way I read it, you would be required to report the uncertainty on each report, regardless of request.

Good evening. I am an auditor and I went through a few audits with the new norm. It is indeed a shall but you have several ways to handle this.

You can specify that you report values without the uncertainty but you must mention that it is available.

You can avoid to use it BUT it is better to manage this and have a customer info/approbation before issuing reports

In some firelds of application (water in Europe), if you respect the performance requirements of the regulation, you can even report conform/not conform status of a parameter without taking into account the uncertainty, if you do not comply with the regulation, you must report a value and it’s uncertainty
