BS EN 50289-4-16 is a European standard that focuses on environmental test methods for circuit integrity under fire conditions. BS EN 50289-4-16 specifies the criteria for circuit integrity of control and communication cables – wires, symmetric cables, and coaxial cables with metallic conductors for use in e.g. telecommunication, data transmission, radio frequency, video communication, and signaling and control equipment.
BS EN 50289-4-16 on environmental test methods for circuit integrity under fire conditions is useful for:
Circuit integrity (continuity of signal supply) is based upon the maximum frequency for which the cable is specified in combination with the related transmission performances.
BS EN 50289-4-16 provides guidance on circuit integrity, circuit integrity classification, test procedure, the functional requirement (ph or p), and interpretation.
The criteria that are used in BS EN 50289-4-16 defining fire resistant cables are deemed to demonstrate the ability of the cable to provide circuit integrity when subjected to fire. BS EN 50289-4-16 also specifies characteristics that shall be used to define the continuous maintenance of circuit integrity under fire conditions for communication cables.
The purpose of BS EN 50289-4-16 is to provide information as to the derivation of the fire resistance classification (PH or P) for circuit integrity from test data.
