NFPA 2112 STANDARD ON FLAME RESISTANCE GARMENTS FOR PROTECTION OF INDUSTRIAL PERSONEL AGAINTS FLASH FIRE

PERFORMANCE REQUIREMENTS


Thermal Protective Performance (TPP):  Shall be have a “spaced” TPP rating of not less than 25 J/cm2(6.0 cal/cm2) and a “contact” TPP rating of not less than 12,6 J/cm2 (3.0 cal/cm2)

ASTM D6413

Flame resistance flame (vertical test) Fabric and reflective striping utilized in the construction of flame-resistance garments shall have a char length of not more than 100 mm ( 4 in) and an afterflame of not more than 2 seconds, and shall not melt and drip.

AATCC 135

Heat and thermal shrinkage resistance test.  Fabrics utilized in the construction of flame-resistance garments, excluding manufacturers’ labels, shall be individually tested for thermal shrinkage resistance and shall not shrink  more than 10% in any direction.

ASTM F 1930

Manikin Test. The garment fitted on a manikin with 100 sensors in stationary conditions must be tested against the exposure to flash fire for 3 seconds and the heat flux 84 KW /m² to provide predictions of skin burns.
The result of the average prediction of burns can not exceed 50%.

  • Number of test: 3

  • Pretreatment: 1 wash cycle as specified by the manufacturer

  • Exposure time: 3 seconds

  • Underwear: underpants of 170 g / m2 ± 5% made of 100% cotton and short-sleeved shirt of 140 g / m2 ± 5% made of 100% cotton.

  • Requirements: predicting total burns ≤ 50%
