Safety Footwear American Standards ASTM F2413-05

NewsID:232    Datetime:2011-01-19

 

American Standards ASTM F2413-05
ASTM F 2413-05 provides test methods and performance standards for "Personal Protective Footwear" sold in the United States. Saicou protective safety footwear we propose are in compliance with the following requirements :

"I" and "C" Markings - Impact and Compression Resistance
This is a test of a shoe's capacity to protect the toe area of the foot against falling objects or heavy rolling objects such as a forklift. The toe area is protected by using protective toe cap
construction, commonly referred to as "Steel Toes," although some Iron Age/Knapp safety shoes use a Non-Metallic protective cap that is equally effective.
There are 2 levels of protection available for Impact (I) and Compression (C) resistance - Class 50 and 75. Class 75 is the highest and it is recommended for most applications.

Impact :
I/75 = 75 ft. lbf (101.7 Joules)
I/50 = 50 ft. lbf (67.8 Joules)
Compression :
C/75 = 2500 lbs (1100 Kg)*
C/50 = 1750 lbs (790 Kg)

*when a 50-pound (22 Kg) weight is dropped from eighteen inches (45 cm) onto the protective cap
Test Clearances after test for impact and compression :
- 0.500 inch (12.7mm)
"M" Marking - Metatarsal
Established standards for the protection of the upper foot (metatarsal bones) and toe areas. Designed to prevent or reduce injuries when the toe and metatarsal areas of the foot are exposed to "drop" hazards.
There are 2 levels of protection available for - Class 50 and 75.
Class 75 is the highest and it is recommended for most applications.
The impact energies (75 and 50) are the same as for the toe impact.
Test Clearances after the metatarsal test impact are :
- 1 inch (25.4mm)
"EH" Marking - Electrical Hazard
EH footwear is designed to reduce the hazards due to the accidental contact of the sole with electrically energized parts and to provide secondary electrical-hazard protection on substantially
electrically insulated surfaces, live electrical circuits, electrically energized conductors, parts, or appartus under dry conditions.
Electric shock resistant footwear must be capable of withstanding the application of 14,000 volts at 60 Hz for 1 minute with no current flow or leakage in excess of 3.0 milliamperes under dry
conditions.
