Low temperature spec for a power cable

Globetek power cord 1191068F0701-LF matches the specs I need except there is no low temperature spec given. How can find if there is a low temperature spec for this power cord?

Medical grade NEMA 5-15P to IEC 320-C13 typically have temperature range of -20°C to 60°C. I was not able to verify this on 1191068F0701-LF and have submitted a request to GlobTek. I will update this post once once a response has been received.
