Breakthrough time gloves
WebGloves. Supported Gloves are specified by glove weight, not thickness. Specific Gloves Used for Testing One glove has a breakthrough time of just 4 minutes. It is rated “very good,” while another with a breakthrough time of 30 minutes is rated only “fair.”Why? The reason is simple: in some cases the rate is more significant than the time. WebObviously, the greater the breakthrough time, the more protective the material is for that particular chemical. Breakthrough is measured using a standardized test (ASTM F739). Other considerations. In addition to permeation, degradation, and breakthrough, there are other considerations when buying chemical protective gloves and clothing:
