CATEGORY S3 DEFINITION
● The S3 category in safety footwear follows the EN ISO 20345 standard.
● This category includes all protection features of SB, S1, and S2 categories.
● The S3 classification ensures safety against mechanical, environmental, and liquid hazards. 🥾
MANDATORY PROTECTION FEATURES
● All S3 footwear has a toe cap resistant to impacts of up to 200 joules.
● The heel area is closed and absorbs energy to reduce strain.
● The footwear is antistatic to prevent the accumulation of static electricity. ⚡
RESISTANCE TO LIQUIDS AND CHEMICALS
● The upper material resists penetration and absorption of water.
● The outsole resists degradation from contact with hydrocarbons.
● These protections improve durability in wet or chemically exposed environments. 💧
SOLE AND GRIP DESIGN
● S3 footwear includes a penetration-resistant midsole.
● The outsole has slip-resistant properties to reduce fall risks.
● Tread designs with cleats improve grip on soft or uneven surfaces. ⛰️
CATEGORY COMPARISON
● The SB category includes only the protective toe cap.
● The S1 category adds antistatic properties, closed heel, energy absorption, and hydrocarbon resistance.
● The S2 category adds water penetration resistance in the upper material. 📊
EN ISO 20345 STANDARD
● EN means European Norm or European Standard, valid across the European Union.
● ISO means International Organization for Standardization, a global standardization body.
● The number 20345 identifies the specific standard for safety footwear. 📄
LEARNING OBJECTIVE
● The reader understands that S3 footwear under EN ISO 20345 offers complete protection by combining impact resistance, slip prevention, liquid resistance, and puncture protection for demanding work environments.
