[BBP] Blood-borne pathogens [ASTM f1671-13]
Blood-borne pathogen penetration compliant, for at least one hour when tested according to ASTM F1671-13, Standard test method for resistance of materials used in protective clothing.
[EH] ELECTRIC HAZARD [ASTM F2413-18 OR ASTM F2892-18]
Constructed or manufactured with electric shock-resisting soles and heels capable of withstanding an application of 18,000 volts (root mean square (RMS) value) at 60 Hz for 1 minute, with no current flow or current leakage in excess of 1.0 milliamperes under dry conditions.
3MTM ThinsulateTM Insulation, the original thin insulation designed specifically for footwear.
Made in the USA with USA and globally sourced components.
[MT] metatarsal [astm f2413-18]
footwear retains a1” clearance for men’s and .937” clearance for women’s, after a nominal impact of 75 foot lbs. (101.7J), i.e., a 50 lb. weight dropped, reaching 117.9 +/- 2.4” per second velocity at impact 3.5” in from the toe of the footwear (3.375” on women’s).
I-met2® patented technology
Exclusively from Thorogood® footwear. The polymer compositeound used in the I-MET2® absorbs and deflects impact to the instep of the foot. Like the original I-MET®, I-MET2® is an internal, invisible, Metatarsal Guard that is compositeletely integrated with the protective toe cap.
These styles are 100% non-metallic utilizing composite safety toes and non-metallic hardware (eyelets). These features will not activate security screening devices.
The outsole is designed to withstand or reduce damage due to oil.
[PR] Puncture-resisting [ASTM F2413-18]
Puncture-resisting through the sole at a force load of 1200N (270 IBF). Unique textile insole material is flexible and puncture-resisting.
SAFETY TOE BOOTS [ASTM F2413-18]
All boots featuring a safety toe either steel or composite meet or exceed the falling IMPACT and COMPRESSION testing.
[I] IMPACT: Footwear retains a .500 inch (1/2 inch) for men’s and .468 inch (15/32 inch) for women’s or greater clearance after a nominal impact of 75 foot-pounds (101.7J), i.e., a 50 pound weight dropped, reaching 117.9 ± 2.4 inches per second velocity at impact.
[C] COMPRESSION: Footwear retains a .500 inch (1/2 inch) for men’s and .468 inch (15/32 inch) for women’s or greater clearance after a compression force of 2500 lbs. (11,121 N).
[SR] SLIP-RESISTING [ASTM F3445-21]
Footwear is tested for ASTM F3445-21 industry criteria for slip-resisting footwear.
SD footwear will provide for a resistance of between 10 to the 6th power ohms (1megohm) and 10 to the 8th power (100 megohms) resistance when 50 volts are applied via an electrode to the hand of a person wearing the SD test samples on a conductive ground plate.
