Overall Chemical Protection Rating
Protection rating is determined by taking into account the effects of both permeation and degradation in an attempt to provide users with an overall protection guideline when using our glove products against specific chemicals

 
   0    For Splash Protection Only, change glove immediately when chemical contacts glove
   1    Change glove after 5 to 30 minutes of exposure to chemical
   2    Change glove after 31 to 60 minutes of exposure to chemical
   3    Change glove after 61 to 180 minutes of exposure to chemical
   4    Change glove after 181 to 300 minutes of exposure to chemical
   5    Change glove after 301 to 480 minutes of exposure to chemical

The chemical test data and overall chemical protection rating should not be used as the absolute basis for glove selection. Actual in-use conditions may vary glove performance from the controlled conditions of laboratory tests. Factors other than chemical contact time, such as concentration and temperature, glove thickness and glove reuse, may also affect performance. Other glove requirements, such as length, dexterity, cut, abrasion, puncture and snag resistance, or glove grip also need to be considered in making your final selection.
