Elevated-Temperature Oxygen Index Tester ISO 4589-3
Introduction:
Elevated-temperature Oxygen Index Tester is designed and produced according to ISO4589-3 (Elevated-temperature test) and British naval engineering standards NES 715. Elevated-temperature Oxygen Index Tester is based on the common intelligent oxygen index tester, and the electric heating device is added in the position of the combustion cylinder, so the mixed gas can be preheated; This apparatus can test the ignition temperature of different materials at a certain concentration of oxygen; it is also can test combustion performance of vertical self-supporting bars of plastic material or thickness of 10.5mm plastic sheets, also suitable for vertical support film or film material was tested.
Standards:
ISO 4589-3 Plastic- Determination of burning behavior by Oxygen index
NES 715 Determination Of The Temperature Index Of Small Specimens Of Material
Technical Parameters:
1, The oxygen concentration measuring range: 0-90%;
2, The oxygen concentration in the accuracy of ± 0.1%;
3, Nitrogen mass Flow Controller range is 1.0~15.0L/min, the precision is 2%;
4, Oxygen mass Flow Controller range is 1.0~15.0L/min, the precision is 2%;
5, Sensor response time is less than 2 seconds;
6, The response time of the tester is less than 10s (The whole machine response time includes the oxygen concentration setting, regulates the flow with a mass flow controller and fully mixed by the mixing tube, and then out of the combustion tube. ) ;
7, Flow meter range: 1.0~15.0L/min;
8, The combustion cylinder airflow rate is 40mm/s ± 2mm/s, concentration regulation accuracy is ± 0.1%;
9, The gas flow rate on top of the combustion tube is 90mm ± 10mm/s;
10, The portable ignition, injection down 16 ± 4mm, can be adjusted ;
11, The measurement time is more than 5min, and accuracy is ± 0.5s;
12, Double flow meter and pressure gauge: Accuracy ± 1%.
13, Work pressure is 0.1Mpa;
14, Glass cylinder height 500mm, inner diameter 80mm.
Main Features:
Heating unit:
1, The heating device power is 1000W;
2, Test tube test temperature is 25 C ~400;
3, a Heating device equipped with thermal insulation;
4, The heating pipe temperature accuracy: 125ºC below 2 degrees, 125ºC above + 3 C (according to the standard requirements).
Control System:
1, PLC touch screen with a higher degree of test automation;
2, The system automatically adjusts the oxygen concentration after the value is set;
3, The key electrical components are imported brand, accurate, reliable, and durable;
4, This tester is equipped with an automatic calibration system to avoid the influence of the oxygen sensor on the test results due to the drift of the environmental impact.
5, One-button sensor automatic calibration system is convenient and efficient, to avoid customers' need to be equipped with standard gas periodic calibration trouble.
6, With a safety protection circuit.
Our company:
Since 2008, Gold has developed 70 kinds of fire testing instruments and served many industries such as building materials, aviation, rails, IMO, wire & cable, safety protection, and so on.
