Flame Retardant Tester for Electrical Conduit Tubes
Category：Material Combustion Tester
Introduction
The Flame Retardant Tester for Electrical Conduit Tubes is designed to evaluate the self-extinguishing and flame retardant performance of electrical conduit tubes and accessories. It is developed according to JG3050-1998 and GB/T 13823.3 standards, specifically meeting the self-extinguishing test requirements (Section 6.10.1). The tester features automatic ignition with a high-voltage igniter, corrosion-resistant design, imported key components, digital timing, and programmable test procedures for reliable and convenient operation.
Application
This tester is widely used for:
(1) Testing flame-retardant and self-extinguishing properties of PVC, PE, or other polymer electrical conduit tubes.
(2) Quality control in electrical accessories manufacturing and inspection.
(3) Verification of flame retardancy for compliance with national and international standards.
(4) R&D of fire-retardant additives for insulated tubing.
(5) Educational institutions and laboratories for teaching electrical insulation material safety.
Tested products include: electrical conduit tubes, flexible cable sleeves, insulating tubing, and related accessories.
