Main mechanical Factory Routine Test

Parameter	Test method	Test conditions	Acceptance criteria*
Tensile strength	IEC 60794-1-21-E1	As per cable maximum tensile strength (max. Working tension) in table above	After 30 minutes the maximum strain on the fibre should not exceed 0.2% and no attenuation change throughout test
Crush	IEC 60794-1-21-E3	Short time: 10 min Long time: 120 min Load: As per maximum crush resistance in table above Number of positions: 3 adjacent sections (ensuring one over tube and one over lay reversal	No damage to the sheath or to the core structure and no attenuation change throughout test
Impact	IEC 60794-1-21-E4	Weight: 1.5 kg Height: 1.0 m Anvil radius: 12.5 mm Impacts: 1	After 5 minutes no fibre breaks, no damage to the sheath or to the core structure and no attenuation change throughout test
Torsion	IEC 60794-1-21-E7	Sample length: 1 m Rotation: a) 180º clockwise, b) return to starting position, c) 180º anticlockwise, d) return to starting position. Four movements constitute one cycle). Complete 10 cycles (a to d) in one minute maximum	During the final tenth cycle at a), c) and after completion (no rotation) check transmitting fibres. No fibre breaks, no damage to the sheath or to the core structure and no attenuation change throughout test
Bend Bend under tension	IEC 60794-1-21- E11 Concurrent to tensile test IEC 60794-1-21-E18A	Mandrel diameter: 30 x Cable OD Bend: 360º (1turn) Mandrel diameter: 40 x Cable OD Bend: 360º (1turn)	No attenuation change throughout test After 1minutenofibre breaks, no damage to thes heath or to the core structure and no attenuation change throughout test
Temperature cycling	IEC 60794-1-22-F1	Sample length: 1000 m (minimum) Temperature range: – 10 °C to +70 °C
