IEC 60331 Cable Fire Resistance Tester BS 6387 BS 8491 Impact And
Water Spray Test
Cable Fire Resistance Tester Product Introduction:
The fire tester's performance requirements, including fire
resistance, water spray fire resistance, and mechanical fire
resistance tests, are applicable to mineral insulated cables with
rated voltages up to 450/750V, ensuring they maintain circuit
integrity for extended periods under fire. This complies with the
British fire-resistant cable standard, BS6387,IEC
60331-1,-2,-11,-21,-23,-25 ,BS 8491"Specification for performance
requirements for cables intended to maintain circuit integrity
under fire conditions."

Wire and Cables Circuit Integrity Tester Technical Parameters:
• The combustion rack is cabinet-style, with fire-resistant and
impact-resistant brackets adjacent to each other, providing
convenient operation and an aesthetically pleasing appearance.
•Burner: 500mm ribbon-type blowtorch (with venturi mixer). Burner
holes are arranged in three staggered rows, with a hole diameter of
φ1.32mm and a center distance of φ3.2mm. The burner can be adjusted
vertically and horizontally to accommodate the cable's horizontal
and vertical positioning.
•Fire-resistant bracket: Consists of two metal rings, approximately
300mm apart. The inner diameter of the metal ring supporting the
test is approximately 150mm. mm, with a ring cross-section diameter
of 10 ± 2 mm. A clamp is installed at one end of the sample holder
to secure the specimen, while the other end is freely supported to
facilitate heat transfer along the specimen's longitudinal
direction.
•Fire-Resistant Impact Test Stand: 1. For IEC60331-1 specimens with
an outer diameter exceeding 20 mm, the impact test ladder consists
of a steel frame with two central vertical steel members that can
be adjusted left and right. The test ladder is 1200 ± 100 mm long
and 600 ± 50 mm high, with a total mass of 18 ± 1 kg.
2.For IEC60331-2 specimens with an outer diameter not exceeding 20
mm, the test wall consists of a heat-resistant, non-combustible
non-metallic material securely fastened to two horizontal steel
support rods. The length is 900 ± 100 mm, the height is 300 ± 50
mm, and the thickness is 10 ± 2 mm. The support rods are 25 x 25 mm
square steel tubes approximately 1 meter long. The total mass of
the test wall is 10.0 ± 0.5 kg. The impact bracket is secured to a
rigid support rod by four rubber bushings with a hardness of Shore
A50-60. The impact rod is a mild steel round rod with a diameter of
(25 ± 0.1) mm and a length of (600 ± 5) mm, and the impact rod
angle is 60°. Both impact brackets are removable and
interchangeable.
•Sample applied voltage: AC 100V-1000V, adjustable;
•Sample short-circuit breakdown current: 2A;
•Sample holding current: 100-260mA, adjustable;
•Three-phase transformer: 380V, 9kVA;
•Specimen short-circuit or open-circuit will stop the flame supply
and cut off the voltage, and the software will display a fault
message;
•Flame supply time: Adjustable from 0 to 999 minutes;
• Two φ1.5mm thermocouples and a corresponding thermometer for
flame correction display flame temperature;
•Gas source control and regulation: Air flow rate is adjustable
from 20 to 200 L/min using a mass flow meter; propane flow rate is
adjustable from 2 to 20 L/min using a mass flow meter;
•Control method: Computer software controls the operation,
monitoring current, voltage, gas flow rate, test results, and graph
printing during the test.
