UL94 Horizontal and Vertical Flame Test Apparatus

1.Introduction

HVR-4 Horizontal and vertical flame test apparatus is designed according to UL94, IEC60695-11-4 and IEC60695-11-3. The fire hazard is evaluated by burning rate, after glow time, after flame time and damage length of the specimen. HVR-4 horizontal and vertical flame test apparatus is applied to the V-0, V-1, V-2, HB and 5V materials, it is widely used in the R&D department, QC department and production department of lighting equipment, low-voltage apparatus, household appliance, motor and etc.. And also can be used in the industries of insulation material, plastic and other solid combustible material.
