  • After flame time (s): No – PASS
  • Afterglow time (s): No – PASS

 

  1. Fabric tensile strength and rupture elongation (ISO 13934-1:2013)
    The relative expanded uncertainty of Tear resistance is ±3.9% assay value of the measured, for a probability of coverage of 95%. Is determined the Lengthwise and Crosswise directions, respectively.

REQUISITE ACCORDING TO EN ISO 11612:2015

The external material must resist a determination of tear resistance in both directions ≥ 10 N.

  • Warp: 1300NPASS
  • Weft: 960NPASS

  1. Contact Heat (ISO 12127-1:2015)  – performance level F1
  • Average threshold time (S): 7,6

ISO 12127-1:2007 specifies a test method for the determination of contact heat transmission. It is applicable to protective clothing (including hand protectors) and its constituent materials intended to protect against high contact temperatures. ISO 12127-1:2007 is restricted to contact temperatures between 100°C and 500°C.

The performance requirements set out in ISO 11612:2015 are applicable to garments which could be worn for a wide range of end uses, where there is a need for clothing with limited flame spread properties and where the user can be exposed to radiant or convective or contact heat or to molten metal splashes.

Madeira-320 flame retardant fabric is made of 350 gsm cotton with antistatic yarn and designed for use in Metallurgy and other industries. This fabric is best used for protective jackets, pants, overalls and other FR clothing.
