The purpose of this part of IEC 61300 is to ensure that the retention or attachment of the fibre, cord or cable in a fibre optic device or an enclosure will withstand tensile loads likely to be applied during normal service.
The purpose of this part of IEC 61300 is to ensure that the retention or attachment of the fibre, cord or cable in a fibre optic device or an enclosure will withstand tensile loads likely to be applied during normal service.
This part of IEC 61300 defines a test method to reveal mechanical weakness and/or degradation of fibre optic devices when subjected to repetitive or non-repetitive mechanical shocks. It simulates infrequent repetitive or non-repetitive shocks likely to be encountered in normal service or during transportation.
This part of IEC 61300 evaluates the effect of loads which is possible to occur when fibre optic devices are exposed to critical situations such as being stepped on, being run over by vehicle tyres, when an evenly-distributed static load is applied to the top surface of a street cabinet or when a load is applied to a street cabinet's open door.
This part of IEC 61300 describes a procedure for determining the suitability of a fibre optic interconnecting device or a passive component to withstand exposure to the optical power which occurs during its operation.
This part of IEC 61300 applies an overload torque to twist-type coupling mechanisms. It isapplicable to threaded or bayonet-twist type coupling mechanisms. It can be used to ensurethat the coupling mechanism of a connector set or connector-device combination will withstandthe torsional loads likely to be applied during normal service.
Deals with the determination of effects of dust on fibre optic devices.
Determines the effect on a fibre optic device of reduced air pressure, such as might be encountered at high altitudes. This procedure is conducted in accordance with IEC 68-2-13, test M.
