IEC 60332-3-10 Bundled Wire And Cable Combustion Test Machine Heat Release Test

Bunched Cable Vertical Combustion Tester Product Description:

The bundled cable combustion test system is designed and developed in strict accordance with the international standard IEC 60332-3-25 "Vertical flame spread test of cables under flame conditions - test method for vertical arrangement of bundled cables". It is specially used to evaluate the flame retardant performance and longitudinal flame diffusion characteristics of various types of vertically laid power cables, communication cables and optical fiber composite cables under the action of standard fire sources. As a key testing equipment in the cable industry, the system can accurately simulate fire conditions in multiple scenarios. It is a core test device for testing the fire safety performance of bundled laying products such as communication cables, rail transit cables, and flame-retardant cables for construction, providing an important technical basis for cable flame retardant grade certification.
