gui chao cable news: how the flame retardant oxygen index of the cable?-非凡电子娱乐

now, many provinces and cities and regions of the wire and cable factory encountered a more troublesome problem.

now is not to increase product quality supervision and inspection efforts?

some of the local quality supervision and inspection departments do not have their own wire and cable into a bundle of combustion test methods,

it is impossible to do the experiment on the wire and cable samples extracted from the market,

therefore, the flame retardancy of the product is judged by the oxygen index of the cable.

they measured the oxygen index of combustibles in all kinds of wire and cable, then the average value.

if the average value is consistent with the requirements of flame retardant, the product is judged to be flame retardant, otherwise it is not qualified.

in view of this situation, the wire and cable manufacturers must pay attention to the product structure of combustible material oxygen index,

good quality of incoming materials.

the corresponding relationship between the oxygen index (loi) and the flame retardancy of the material is as follows:

loi < 23 combustible

loi 24 - 28 slightly flame retardant

loi 29 - 35 flame retardant

loi > 36 high flame retardant
