IEC60332-1 Flammability Testing Equipment Single Cable Vertical Burning Test Device
Purpose of examination:
When the wire and cable products are short circuited or contact with fire, the insulation or sheath may burn. In many occasions (coal mine, ship, subway, etc.) that require strict prevention of fire, the flame shall not spread in case of combustion, but extinguish itself in a certain time and length, which is called flameless. In some cases, if the product does not have this performance, it will cause very serious consequences.
PVC, chloroprene rubber and NBR PVC Composites and chlorinated polyethylene are widely used as insulation and sheath materials for products with non flame retardancy. Chlorine gas will be released when these materials are burned to play a flame retardant role. Sometimes in order to enhance the effect of flame retardant, some flame retardant is added. Other materials such as polyolefin can also meet the requirements of flame retardancy (and low smoke and halogen-free) by adding flame retardants.
Flammability Testing Equipment
Standard:
IEC60332-1-1 ‘Tests on electric and optical fibre cables under fire conditions – Part 1- 1: Test for vertical flame propagation for a single insulated wire or cable – Apparatus’. IEC60332-1-2 ‘Tests on electric and optical fibre cables under fire conditions – Part 1- 2: Test for vertical flame propagation for a single insulated wire or cable – Procedure for 1 kW pre-mixed flame’. IEC60332-1-3 ‘Tests on electric and optical fibre cables under fire conditions – Part 1- 3: Test for vertical flame propagation for a single insulated wire or cable – Procedure for determination of flaming droplets/particles’. Flammability Testing Equipment
Application:
It simulates the influence of early-stage flame when there is a fire around the electric and electronic products, so that to judge the igniting danger degree. Suitable for vertical burning test of single cable or optical cable products, determine the combustion characteristics of insulating materials.
Feature:
This series of products adopt integral type inlet ignition system. The combustion time delays 0.1S thus to make sure the sufficient time of gas burning. They are with matte black background, multi-functional flame measure gauge, stainless steel of box full, large observation window, imported digital indicator of high precision, nice appearance. And they gather a number of advantages of similar products home and abroad.
