■ HB ( Horizontal Burn ): slow burning on a horizontal specimen ; burning rate < 76 mm / min for thickness < 3 mm or burning stops before 100 mm . ) The burning rate is less than 3'/ min or stops burning before the 5” mark . HB rated materials are considered " self - extinguishing ".( ■ V -2 ( Vertical Burn ): burning stops within 30 seconds on a vertical specimen ; drips of flaming particles are allowed . ■ V -1 ( Vertical Burn ): burning stops within 30 seconds on a vertical specimen ; drips of particles allowed as long as they are not inflamed . ■ V -0 ( Vertical Burn ): burning stops within 10 seconds on a vertical specimen ; drips of particles allowed as long as they are not inflamed . ■ 5 VB ( Surface Burn ): burning stops within 60 seconds on a vertical specimen ; no drips allowed ; plaque specimens may have a burn - through ) a hole (. ■ 5 VA ( Surface Burn ): burning stops within 60 seconds on a vertical specimen ; no drips allowed ; plaque specimens may not have a burn - through ) no hole (.
