Protective clothing to protect
against heat and flame.
EN ISO 11612 specifies the
requirements for heat and
flame-resistant clothing that covers
the entire body, excluding hands,
feet, neck and head. In addition to
limited flame spread (A1/A2) the
clothing must also provide
protection against one other source
of heat. The levels or protection
offered by an EN 11612 compliant
garment are expressed in code
letters and numbers listed after the
standard on the garment CE label
and user information sheet.
Flame spread
• A1: Surface ignition
• A2: Edge ignition
Convective heat
• B: 3 classes (B1, B2, B3), where 3
indicates the highest class and
highest protection level.
Radiant heat
• C: 4 classes (C1, C2, C3, C4), where
4 indicates the highest class and
highest protection level.
Molten aluminium
• D: 3 classes (D1, D2, D3), where
3 indicates the highest class and
highest protection level.
Molten iron
• E: 3 classes (E1, E2, E3), where 3
indicates the highest class and
highest protection level.
Contact heat
• F: 3 classes (F1, F2, F3), where 3
indicates the highest class and
highest protection level.
In addition to requirements for
flame-resistance and heat
protection, the standard also sets
the requirements to mechanical
strength, design and provision of
information (user manual).
EN ISO 61482-1-2
EN ISO 11611
Protective clothing for use in
welding and allied processes.
EN ISO 11611 specifies the
requirements for welding clothing,
including, welding hoods, aprons,
sleeves and gaiters. The require-
ments are also for clothing worn
during welding associated
processes with similar risks.
The clothing is intended to protect
against small splashes of molten
metal, short contact with flame,
radiant heat and minimizes the
possibility of electric shock due to
short contact with electrical
conductors (max voltage 100V DC).
Perspiration and pollution can
affect electrical conductivity.
The welding standard has
2 classes:
• Class 1 for regular welding
• Class 2 for heavy duty welding
The primary difference between
the classes is the amount of weld
splatter, the degree of radiant heat
and also tear strength. Class 2 will
only be awarded if all requirements
have been met.
Flame spread
• A1: Surface ignition
• A2: Edge ignition
Radiant heat
• Class 1: RHTI24 > 7 seconds
• Class 2: RHTI24 > 16 seconds
Impact of small metal splashes
• Class 1: > 15 splashes
• Class 2: > 25 splashes
Electrical resistance
• Rv > 105 Â.
Tear strength
• Class 1: > 15N
• Class 2: > 20N
In addition to requirements for
protection against flame, heat and
electrical resistance it also sets a re-
quirement for mechanical strength,
design and provision of information
(user manual).

Where an IEC 61482-2 garment is certified to the 2009
edition of the standard, the double triangle pictogram will
be displayed on the garment CE label and user information
document. When an IEC 61482-2 garment is certified to the
2020 edition of the standard, the arc flash pictogram will be
displayed on the garment CE label and user information
document. Ballyclare has included the arc flash pictogram
on the compliancy prints of our multinorm range to show
that the fabric has been tested to the requirements of EN
61482-1-1:2019 specifically for the ELIM rating. This can be
found listed below the Cal rating within each garment.
