Needle Flame Tester,
Needle Flame Test Apparatus
Tracking tester(Tracking Index Test)is a simulation experiment project using non-flame ignition source in accordance to standard requirements of IEC60112 ,UL 746A ,GB/T4207,GB4706.1,ASTM D 3638-92,etc.
tracking test of leakage current (Tracking Index Test)on the surface of solid insulating material between platinum electrodes in required size ( 2mm × 5mm ),is to exert voltage and drip down a conductive liquid (0.1%NH 4 CL) in required droplet volume at a certain time(30s) and certain height(35mm) ;to evaluate the resistance of electric leakage performance on the surface of solid insulating material in electric field and moist or contaminant medium, under the joint effect;determine Comparative Track Index (CT1) and proof tracking index (PT1) .Dielectric Tester(Tracking Index Tester) is suitable for research,production and quality testing department of lighting equipment,low voltage apparatus,household appliance,machine tool electric appliance,motor-driven machine,electric tool,electronic instrument,electronic gauges and information technology devices;also suitable for insulating material,engineering plastic,other solid combustible material,electrical connectors and accessories industry.

* this tester should be placed on a level table
* table size no less than 1500W * 900D * (600-800)H mm
* distance to the wall: > 200mm
* exhaust pipe: diameter of 100mm
* the test room should be independent room equipped with exhaust system and firefighting device
2.1) install the exhaust pipe, tighten the fitting
2.2) check the power supply wiring, ensure it’s correct and grounded
2.3) make up test resolution, and adjust the dropping device accord to standard requirements of:
|Test solution A (CTI A)||395 Ωcm|
|Test solution B (CTI B)||198 Ωcm|
Drops of solution fall on to the specimen at intervals of 30±5s;
The drops shall fall more or less centrally between the electrodes from a height of 35±5mm;
The time for 50 drops to fall on to specimen shall be 24.5±2min;
The mass of a sequence of 50 drops shall lie between 0.997g and 1.147g;
The mass of a sequence of 20 drops shall lie between 0.380g and 0.480g.
Solution prepared should be used within 4 hours to ensure conductivity qualified.
Filling the solution after its full melted, preventing particles clog pipes.
Emptying the liquid when test finished, and wash the pipe with water.
2.4) specimen preparation
The specimen should be flat and clean, flat surface no less than 20mm*20mm, thickness of specimen shall be 3mm or more.
2.5) electrode installation
Adjust the angle(60±5°)and distance(4±0.1 mm) between two electrodes;
Adjust the pressure by move the weight to 1±0.05N；
Fix the screws, and close the window.
