The heat and flame protection performance rating of a glove measures how easily a glove will ignite, and if ignited, how readily it will continue to burn once the flame is removed. When a glove is tested in accordance with ASTM F 1358-08, the glove’s ignition resistance and burning behavior is classified as shown below:
| Niveau | Time Exposed to Flame (seconds) | After-Flame Time (seconds) |
|---|---|---|
| 0 | 3 | < 2 |
| 1 | 3 | ≥ 2 |
| 2 | 12 | < 2 |
| 3 | 12 | ≥ 2 |
| 4 | No ignition in either 3- or 12-second exposure period | |
Materials that show no ignition or longer ignition times and short after-burn times are considered to perform better.
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.
