Fibre optic interconnecting devices and passive components. Basic test and measurement procedures - Tests. Thermal shocks Ingestion-build-156411 ― bolted manholes for tank1 Scope This part of IEC 61300 details a procedure for determining the suitability of a fibre optic device to withstand the effects of thermal shock. In practice, this means a very short change over time between extreme temperatures.
