EN 13832-3:2006 - Footwear protecting against chemicals - Part 3: Requirements for footwear with a high level of resistance to chemicals under laboratory conditions

EN 13832-3:2006 this standard specifies requirements for all-rubber and all-polymeric footwear designed to provide a high level of resistance to specific chemicals. This footwear resists both degradation (by at least 3 chemicals in the list provided) and permeation (i.e., providing at least Level 1 resistance against 3 of the chemicals listed). This standard specifically excludes leather footwear and low shoe and ankle boot designs.
Part 3 of EN 13832 describes the situations where the wearer is advised to select high-resistance footwear (e.g., when working with especially aggressive chemicals). Unlike part 2, part 3 requires that tests be conducted on footwear’s resistance to chemical permeation and chemical degradation resistance and includes five performance levels.

Performance levels:
Level 1 - 121 to 240 minutes
Level 2 - 241 to 480 minutes
Level 3 - 481 to 1440 minutes
Level 4 - 1441 to 1920 minutes
Level 5 - >1921 minutes

Stated chemicals (at least 3 from the list below):
• B – acetone
• D – dichloromethane
• F – toluene
• G – diethylamine
• H – tetrahydrofuran
• I – ethyl acetate
• J – n-heptane
• K – 30% sodium hydroxide
• L – 95% sulphuric acid
• M – 65% nitric acid
• N – 99% acetic acid
• O– 25% ammonia solution
• P – 30% hydrogen peroxide solution
• Q – isopropanol
• R – 13% sodium hypochlorite
