Product Description
The VW-1 Horizontal Vertical Flame Tester is professional testing equipment designed according to international wire and cable flame retardant performance standards, specifically the VW-1 test method in UL 1581. This instrument evaluates the vertical combustion flame retardant performance of insulating sheath materials including wires, cables, and optical fiber cables when exposed to specified flames under controlled conditions.
Core Functions and Applications
This tester simulates real-world scenarios where wires and cables encounter external open flames in vertical installations. It evaluates critical safety parameters including flame spread prevention, self-extinguishing capability, and whether burning dripping materials ignite underlying cotton substrates.
Compliance and Certification
Primarily meets UL 1581 Section 1080 (VW-1 Vertical Specimen Flame Test) requirements. Compatible with vertical combustion tests in IEC 60332-1, CSA C22.2 No. 0.3, and GB/T 18380.12 standards. Passing this test is mandatory for obtaining UL VW-1 certification.
