Heat Resistant Gloves - The difference between Contact Heat Gloves & Radiant Heat Gloves.

 

Both contact and radiant heat resistant gloves are frequently used in the foundry industry, where workers are constantly exposed to materials that exceed thousands of degrees in temperature. Whilst the difference between these two types of gloves is small, using the incorrect glove can result in serious injury.

Radiant Heat Resistant gloves like the one pictured (left), have an aluminised backing to reflect the radiant heat that comes off the molten material. Depending on the melting material this residual heat can often range from 400°C to 1200°C.

 

All Elliotts’ Radiant and Contact heat gloves have been independently tested to AS/NZS 2161.4:1999 – Protection against thermal risks (heat and Fire) EN407. This standard specifies thermal performance for protective gloves against heat and/or fire. The standard consists of six performance level, relating to specific protective qualities. 

 

The AS/NZS 2161.4:1999 Section D applies to radiant heat gloves: 

  D. RADIANT HEAT RESISTANCE (PERFORMANCE LEVEL 0-4)

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 is a performance level or 3-4 is obtained in the flammability test.

Radiant Heat is testing according to EN ISO 6942:2002. The back of the sample is exposed to radiant heat density of 20kW/m2 and the time taken for the temperature on the inside of the glove to rise 20°C gives the performance level.

                                                                                                   

 

 

Contact Heat Resistant gloves like the one pictured (right), are made from the same type of fabric as radiant gloves but these gloves do not have the aluminised backing. These gloves are often used when a worker is required to hold an object and where  both sides of the hand may come into contact with the heat source.

 

The AS/NZS 2161.4:1999 Section B applies to radiant heat gloves: 

  B. CONTACT HEAT RESISTANCE (PERFORMANCE LEVEL 0-4)

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.

Contact Heat is tested according to EN 702. Samples are taken from the palm area and placed in contact with a cylinder of the appropriate temperature. To gain the relevant performance level, the temperature of the inside of the glove cannot rise by more than 10°C within the threshold tie.
