Use the right heat resistant gloves for the right application
Both contact and radiation resistant gloves are frequently used in the foundry industry. In the foundry industry, workers are constantly exposed to temperatures in excess of thousands of degrees. Although the difference between these two types of gloves is small, using the wrong gloves can lead to serious injuries.
Radiation-resistant gloves As shown in the photo (left), there is an aluminized backing to reflect the radiant heat emitted by the molten material. Depending on the molten material, this residual heat is often in the range of 400°C to 1200°C.
All Elliotts Radiant and Contact Heated Gloves are independently tested to AS/NZS 2161.4:1999 – Protection against Thermal Risks (Heat and Fire) EN407. This standard specifies the thermal performance of protective gloves against heat and/or fire. The standard consists of six performance levels related to specific protection characteristics.
AS/NZS 2161.4:1999 Section D applies to radiant heat gloves.
|D. Radiation Heat Resistance (Performance Level 0-4)|
It is based on the length of time the glove can slow heat transfer when exposed to a radiant heat source. A performance level shall only be stated if the flammability test yielded a performance level or 3-4.
Radiant heat is tested according to EN ISO 6942:2002. The performance level is the time it takes for the temperature inside the glove to rise by 20°C when a radiant heat density of 20 kW/m2 is applied to the back of the sample.
contact heat resistant gloves
contact heat resistant gloves Made of the same type of fabric as the radiant gloves, as seen in the photo (right), these gloves do not have an aluminized lining. or when both sides of the hand are likely to come into contact with the heat source.
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) where the user feels no pain for at least 15 seconds. If EN Level 3 or higher is obtained, the product must score 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. A sample is taken from the palm of the hand and brought into contact with a cylinder of appropriate temperature. To obtain the relevant performance level, the temperature inside the glove cannot rise above 10°C within the threshold tie.
