Conductivity Water Samples testing temperature

#1
Hello,
We are doing a qualification for a Water Distribution System, as part of Phase-1, we are sending Conductivity water samples to a third-party location for testing. but, the third party received samples at '-2c ' (too many icepacks in the shipping container, shipped overnight) instead of in the range '2-8 c' (According to Standard methods: Examination of water & waste wasters) but we told them to continue with testing. Is there any guidance we can follow, instead of discarding the result if we can anyhow save the data by giving proper justification?

Conductivity is usually measured at 25C (it can be done at other temperatures with offset applied). If the sample is fully thawed and mixed, the freezing should have no impact on conductivity. Why were your samples shipped under refrigerated conditions?

Thank you for your response
The testing lab we are sending the samples told us to ship them under refrigerated conditions
Is there guidance we can reference to show that freezing conditions don't affect the conductivity test results,? I'm gathering as much information as possible to give justification for this non-conformance
