The conductive heat resistance performance rating of a glove measures the insulation provided by the glove when exposed to and in contact with a hot surface. When a glove is tested in accordance with ASTM F1060-08, the conductive heat resistance is classified as shown below:
|Level||Highest contact temperature (°C) at which both time-to-second degree burn is greater than or equal to 15 seconds and alarm time is greater than or equal to four seconds|
The alarm time is the difference between the measured time-to-second degree burn and the time-to-pain.
Higher temperatures indicate gloves with greater insulation.
The American National Standards Institute / International Safety Equipment Association (ANSI/ISEA) 105-2016 American National Standard for Hand Protection Classification is the latest revision of a voluntary consensus standard first published in 1999, and revised in 2005, 2011 and 2016.
This standard addresses the classification and testing of hand protection for specific performance properties related to chemical and industrial applications. It provides, or refers to, appropriate test methods and provides pass/fail criteria used by manufacturers to classify their products. End users can use this information to review the documentation received from their supplier to help verify the gloves they are considering meet their needs.
