20 Drops - 50 Drops Flammability Testing Equipment WH-8902JK Leakage Tracking Test
Leakage tracking test is the IEC60112: 2003 "solid insulation material resistance to tracking
index and compared to the determination of trace index", UL 746A, ASTM D 3638-92, DIN
53480 standards such as simulation test project.
The tracking test was carried out by dropping a predetermined droplet volume of a
contaminated
liquid (0.1 (0.1 mm)) at a predetermined height (35 mm) between a predetermined size (2
mm x
5 mm) of platinum electrodes on a solid insulating material surface, applying a voltage, %
NH 4
CL) was used to evaluate the ability of the surface of the solid insulating material to combine
with the electric field and the contaminating medium, and to compare the electrical tracing
index
(CT1) and the tracking resistance index (PT1).
Electrical traceability testing instrument for lighting equipment, low-voltage electrical
appliances,
household appliances, electrical appliances, electrical, electrical tools, electronic equipment,
electrical instruments, information technology equipment research, production and quality
inspection departments, also applies to insulation materials, engineering Plastics, electrical
connections, accessories industry.
