PREFACE

On August 11th 2011, ASTM released its new F2412 and F2413 standards and methods for
testing. Included with the changes was the addition of the F2800 standards.

WATERPROOF (X-TREME®)
Breathable, waterproof lining/ barrier capable of resisting water leakage for 2 hours in 5" of water.

WATERPROOF (SYMPATEX®)
Breathable, waterproof lining/ barrier capable of resisting blood born pathogens.

WATERPROOF (THORO-DRI®)
A waterproof breathable lining/membrane with waterproof taped seams capable of resisting
blood born pathogens. Seam seal: Constructed with waterproof upper materials that have all upper stitch
seams sealed with a waterproof adhesive.

WATER RESISTING (WR)
Leather is chemically treated to resist the effects of high pH environments related to petroleum
expoloration and processing, and animal farming.

INSULATED (THINSULATE®)
Insulation helps keep the foot warm and dry without the extra bulk even on the coldest days.
We carry many styles of work boots and weather boots that have Thinsulate® insulation designed to keep
your feet warm in subzero temperatures. Thinsulate® is a trademark of 3M.

ELECTRIC HAZARD RESISTANCE (EH)
Boots are constructed 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 leakage current in excess of 1.0 milliamperes under dry conditions. Tested for
and meets CAN/ CSA-Z195 ELECTRIC SHOCK RESISTANCE.

STATIC DISSIPATIVE (SD Type 1)
Boots are constructed to provide for a resistance of between 10⁶ (1 meg ohm) and
10⁸ (100 meg ohms) resistance when 50 volts are applied via an electrode to the hand of a person wearing
the SD test sample on a conductive ground plate. SD footwear meets ASTM 2412-11 test requirements.

SAFETY TOE (Steel)
IMPACT: Class I/75 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 from 18 inches reaching 117.9 ± 2.4 inches per second velocity at impact.
COMPRESSION: Class C/75 footwear retains a .500 inch (1/2 inch) after compression of 2500 lbs. (11,121 N)
or greater. Meets ASTM F2413-11 M I/75/C/75 ratings.

SAFETY TOE (Composite)
Class C/75 footwear retains a .500 inch (1/2 inch) after compression of 2500 lbs. or greater.

METATARSAL (M/75)
Class Mt/75 footwear retains a 1.0 inch clearance for men’s and 15/32 inch clearance for women’s,
after a nominal impact of 75 foot pounds (101.7J), i.e., a 50 lb. weight dropped from 23.25 inches reaching
117.9 ± 2.4 inches per second velocity at impact 3.5 inches in from the toe of the footwear
(3.375 inches on womens).

SLIP RESISTANCE (SR)
Footwear meets or exceeds the ASTM F2913-11 SATRA Test Method TM144 Standard for slip resistance.

PUNCTURE RESISTANCE (PR)
PR constructed or manufactured footwear with sole and heel area capable of withstanding
a force load of less than 1200N (270 lbf) according to ASTM F 2412-11 / 2413-11, Standard Test Method for
Foot Protection. Unique textile insole material is flexible and puncture resisting.
