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 |

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

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.
