: A 94V-0 rating guarantees that the PCB material will self-extinguish within 10 seconds of being exposed to a vertical flame and will not produce flaming drips.
This is likely a specific factory or vendor code assigned by Underwriters Laboratories (UL) . Manufacturers use these codes to identify the specific production line or facility that fabricated the raw PCB. sh1 94v-0 datasheet
Materials with this rating must pass a , where a flame is applied to a sample in a vertical position. The criteria include: : A 94V-0 rating guarantees that the PCB
