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 – tetrahydrofuranI
- 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
