Fire retardant EN standards and materials

PROTECTION AGAINST HEAT AND FIRE
Method of test:
Evaluation of materials and
meterial assemblies when exposed
to a source of radiant heat.
PROTECTION AGAINTS HEAT AND FLAMES
Method of test:
Determination of heat transmission
on exposure to flame.
Assessment of resisitance of
materials to molton metal splash.
PROTECTIVE CLOTHING FOR FIREFIGHTERS
Requirements and test methods for
protective clothing for firefighters.
PROTECTIVE CLOTHING FOR USE IN
WELDING AND APPLIED PROCESSES
General requirements.
Does not cover clothing worn
for special welding jobs.
PROTECTIVE CLOTHING AGAINTS
HEAT AND FLAME

Test method for limited flame spread.
PROTECTIVE CLOTHING -
ELECTROSTATIC PROPERTIES

Surface resistivity
(test methods and requirements).












PROTECTION AGAINST HEAT AND FLAME:

Limited flame spread materials or material
assemblies from which garments with limited
flame spread properties are made.

Such information may appear in the
manufacturer's literature.
Markings in the form: EN533 Flame spread
index/Durability.
Flame Spread Index - 1, 2 or 3 - Limited flame spread index
(3 is best). If index 1 materials are present:
Use only over EN533 Index 2 or 3 material
and DO NOT use next to skin.



















PROTECTIVE CLOTHING FOR
INDUSTRIAL WORKERS EXPOSED TO
HEAT: EXCLUDING FIREFIGHTERS
AND WELDING CLOTHING

A - Limited flame spread, and at least one of:
B# - Convective heat resistance (#=1 to 5)
C# - Radiant heat resistance (#=1 to 4)
D# - Molton aluminium splash (#=1 to 3)
E# - Molton iron splash (#=1 to 3)

In all cases, higher number denotes better peformance.
If no number is givern, no protection is claimed.

Example marking

What is Protex/Protal

  • Protex/Protal is a high performance flame retardant (FR) modified acrylic fibre.
  • Protex/Protal is cotton-like in its appearance and feel. it is inherantly fire retardant which means its
    FR is permanent - further treatments or re-treatments are not required.

Multi-Function protection

  • Blends of Protex/Protal fabrics can meet stringent heat and flame protection standards.
    EN531 A, B1, C1, E1.
  • Works with other fibres and/or fabric treatments: anti static (EN1149), chemical resistance
    (EN368), anti-bacterial, thermal power, etc.
  • Pigment printable.
  • High Visibility EN471.
  • Breathable membrane.

Easy to care for

  • FR properly built in: does not wash out.
  • Domestic or industrial laundry: can withstand severe laundry conditions without loss of
    shape, colour or mechanical properties.
  • Dry cleanable and easy-iron.

Good for wearer

  • Permanent protection
  • No additional treatment required
  • Comfortable to wear
  • Easy to home launder
  • Stays looking good
  • Peace of mind

Alternative - treatments

  • PROBAN
  • PYROVATEX
  • Both of the above are treatments that are generally added to the fabric after its manufacture,
    usually used on cotton and cotton blend fabrics.
  • The FR abilities of the fabric created can have very good FR properties; though it is perceived
    and actual permanency is always under question.
  • ZIRPO
  • Used on wool and wool blends, classed as a "permanent treatment" as it physically bonds at
    a "molecular" level with the wool.
