Visual inspection

-

Any one of the three samples indicates that the flag should not burn. Cotton is also not ignited by ignited or hot particles or ignited drops.

Solder heat resistance

-

Pass (only for nominal inner diameter ≤ 5mm hose)

Bending after heating

-

No visible cracks or shedding of the coating (test temperature: 130±2°C, exposure time: 96±1h)

Bending at low temperatures

-

No visible cracks or shedding of the coating (test temperature: ≤-25±2°C)

Mold resistance growth

-

Level 1 or better
