TN1938  Horizontal and Vertical Flammability Tester

 

INTRODUCTION

1.Use the bunsen burner with specified size and specific gas source (methane and propane),to burn samples(90 °and 0 °) with a certain height and a certain angle, then observe whether it is burned,and use The burning time and burning length to evaluate fire risk.

2.this tester is used for the flammability testing of plastic materials such as V-0 V-1 V-2, HB, 5V, HF-1 HF-2, HBF material.

3.It is also suitable for Lighting equipment, low-voltage electrical appliances, household appliances, machine tool electrical appliances, motor, electric tools, electronic instruments, electrical instrumentation, information technology equipment, electrical business equipment, electrical fittings and accessories such as electrical and electronic products and its component parts,Insulation materials, engineering plastic, or other solid combustible materials.
