IEC60332 Single Wire And Cable Vertical Flame Testing Machine
IEC60332 Single Wire And Cable Vertical Flame Testing Machine
Description:
Single Cable Vertical Flame Spread Testing Machine is the most widely used and lower cost of cable fire performance test equipment; It meets the standards IEC 60332-1-1:2004 in the provisions of technical indicators and requirements. Single cable combustion Tester is used to test the flame retardant property of the cable's insulating layer under abnormal conditions such as overheat and over current. It can be used in vertical cable or fiber flame spread test, also can be test the state of flaming droplets during combustion.
Application:
This machine is suitable for the flammability test of various wire and cable insulation covering material PE, PVC and SRPVC. During the test, according to GB/t18380.11-2008 test standard. The two ends of the specimen are fixed and perpendicular to the metal cover of the metal plate. Lighted torch, make the tip of the blue inner cone touch the specimen surface and keep burner and vertical axis 45 °.
GB/T 18380.11-2008 Test for combustion of cables and optical cables under flame conditions - Part 11: Vertical flame spread test for single insulated wire and cable
IEC60332-1-1:2004 Tests on electric and optical fibre cables under fire conditions-Test for vertical flame propagation for a single insulated wire or cable.

It is to use a Bunsen burner of a specified size and a specific gas source (propane) to ignite the test sample in a vertical state at a certain flame height and a certain flame application Angle at regular intervals. The flammability and fire hazard of the test sample are evaluated based on the duration of ignition and combustion of the test sample and the length of combustion.
