Heat & Flame

#

Standard EN407:2004

Gloves giving protection from thermal hazards

Relevant Australian standard: AS/NZS 2161.4:1999

Scope

This standard specifies thermal performance for

protective gloves against heat and/or fire.

Definition and requirements

The nature and degree of protection is shown by a pictogram followed by a series of six performance levels, relating to specific, protective qualities.

The ‘heat and flame’ pictogram is accompanied by a six digit number:

a. Flammability resistance (performance level 0 to 4)

Based on the length of time the material continues to burn and glow after the source of ignition is removed. The seams of the

glove shall not come apart after an ignition time of 15 seconds.

b. Contact heat resistance (performance level 0 to 4)

Based on the temperature range (100-500 °C) at which the user will feel no pain for at least 15 seconds. If an EN level 3 or

higher is obtained, the product shall record at least EN level 3 in the flammability test. Otherwise, the maximum contact heat

level shall be reported as level 2.

c. Convective heat resistance (performance level 0 to 4)

Based on the length of time the glove is able to delay the transfer of heat from a flame. A level of performance shall only

be mentioned if a performance level 3 or 4 is obtained in the flammability test.

d. Radiant heat resistance (performance level 0 to 4)

Based on the length of time the glove is able to delay the transfer of heat when exposed to a radiant heat source.

A performance level shall only be mentioned if a performance level 3 or 4 is obtained in the flammability test.

e. Resistance to small splashes of molten metal (performance level 0 to 4)

The number of molten metal drops required to heat the glove sample to a given level. A performance level shall only

be mentioned if a performance level 3 or 4 is obtained in the flammability test.

f. Resistance to large quantities of molten metal (performance level 0 to 4)

The weight of molten metal required to cause smoothing or pin holing across a simulated skin placed directly behind

the glove sample. The test is failed if metal droplets remain stuck to the glove material or if the specimen ignites.

Gloves must achieve at least performance level 1 for abrasion and tear
