Protective gloves and other hand protection against thermal hazards (heat and/or fire) Only applicable in conjunction with EN ISO 21420:2020, not applicable to firefighter's gloves or welding gloves. Applies to all gloves and other means of  hand protection that protect the hands or parts of the hand from heat and/or fire in one or more of the following forms:


  • Limited flame spread

  •  contact heat

  •  convective heat

  •  radiant heat

  •  small splashes of molten metal

  •  large  quantities of molten metal.

Reading protection levels 

  • Limited flame spread - the surface of the inner layer of the glove should not show any signs of melting.            No holes should appear in any layers of the test area. The seam should not come apart after the ignition time. If the outer layer melts, no molten or burning debris should be released from the material.


  • Contact heat - this test aims to assess how quickly the material transfers heat and how long it maintains its protective properties in thermal conditions. For example, for a contact temperature of 250°C, the glove material must provide protection for at least 15 seconds to achieve performance level 2. The higher the performance level, the higher the contact temperature and the longer the protection time.


  • Convective heat - refers to the assessment of the resistance of the glove material to heat that is transferred by convection, i.e. the process of warm air flowing around the body.


  • Radiant heat - refers to the assessment of the glove material's resistance to heat emitted by radiant sources,   such as a furnace, furnace, or other hot element that emits heat in the form of radiation.


  • Large quantities of molten metal - refers to behavior of the glove material in conditions where large amounts of molten metal are present, such as during work in the metallurgical industry. Effectiveness levels determine the amount of molten iron that is used during the test. The use of molten iron is mandatory during the test, however, if necessary, the glove's reaction to other molten materials, such as aluminum, can also be optionally tested or molten glass. all splashes of molten metal - determines the minimum number of molten metal drops that the glove must withstand, to achieve a certain level of effectiveness.
