30、3, Standard for Fire Tests of Building Construction and Materials. During the fire test, cablesare continuously energized at their maximum rated voltage or maximum utilization voltage (power cables);or at their maximum utilization voltage (control and instrumentation cables) and evaluated for circui
31、tintegrity. Insulation resistance measurements are also taken to quantify leakage current. Following the firetest, the assembly shall be subjected to a hose stream test.1.4 Data cables are subjected to the fire exposure in accordance with CAN/ULC-S101, Standard Methodsof Fire Endurance Tests of Buil
32、ding Construction and Materials, and ANSI/UL 263, Standard for Fire Testsof Building Construction and Materials. During the fire tests, the data cables are evaluated for their abilityto maintain error free data transfer and retrieval at the specified protocol and data rates. Following the firetest,
33、the assembly shall be subjected to a hose stream test.1.5 The fire exposure and hose stream tests are not intended to be representative of all fire conditionsand impact conditions, respectively. It is likely that conditions will vary with changes in the amount, nature,distribution of fire loading, v

These requirementsprovide a relative measure of fire performance of comparable assemblies under these specified fireexposure conditions. It is poss
35、ible that any variation from the construction or operating condition tested,such as size, method of assembly and materials, will substantially change the performance characteristicsof the cables.1.6 The standardized fire and hose stream exposures for comparing the performance of cablesrepresents one
36、 factor in determining the acceptability of cables for use in specific applications.1.7 The construction and operation of the furnace and the general test conditions are intended to be inaccordance with the requirements in CAN/ULC S101, Standard Methods of Fire Endurance Tests ofBuilding Constructio
