Slip Resistant SRC
Slip Resistant SRC: Tested and approved for resistance to slip on a ceramic tile floor coated with a dilute soap solution of sodium lauryl sulphate (NaLS) [SRA] and Slip resistance on steel floor with glycerol [SRB]. The tests measure forward slip on the heel and with the boot flat to the floor. Boot Marking: SRC
Vulcanised Rubber Sole
Vulcanised Rubber Sole Description
Energy Absorbing Heel
Energy Absorbing Heel: Provides a minimum of 20J cushioning at the heel, reducing the risk of fatigue and injury to joints and spine. Boot Marking: E
Toecap and Mid-Sole
Toecap and Mid-sole: Epoxy coated steel toecap fitted tested for 200J impact resistance and 15kN compression. Stainless steel penetration resistant mid-sole fitted with penetration resistance greater than or equal to 1100N. Boot Marking: P
Fuel Oil Resistant
Fuel and Oil Resistant: The outer sole is resistant to oil, ensuring the working life of the boot won’t be compromised if used in oily environments. The test involves immersion in oil for 22 hours after which the sole is checked for excessive swelling, shrinkage or increased hardness. Boot Marking: FO
Cold Insulation
Cold Insulation: The thermal insulation properties of the boot ensure that the temperature decrease inside a boot at 23°C when placed in a cold chamber at -17°C is less than 10°C after 30 minutes when measured at the upper surface of the insole. Boot Marking: CI
Hot Contact
Hot Contact: The sole has been tested for contact with a hot metal surface at 300°C for 60 seconds. Boot Marking: HRO
Antistatic
Antistatic: The electrical resistance of the boot falls between 100 kΩ and 1000 MΩ ensuring that any build up of static charge by the wearer will be conducted safely to earth.
Ladder Grip
