Footwear

ANSI Requirements

Line 1: ANSI Z41 PT 99Indicates the ANSI standard
Letters PT signify the protective toe part of the standard, followed by the last two digits of the year of the standard that the footwear meets (1999)

Line 2: F I/75 C/75Indicates the gender [M (Male) or F (Female)] for which the footwear is intended
Shows the impact resistance (I), impact resistance rating (75, 50, or 30 foot-pounds), compression resistance (C), and compression resistance rating (75, 50, or 30 which correlate to 2500 pounds, 1750 pounds, and 1000 pounds of compression respectively)

Lines 3 & 4: Mt Cd EH PR & SDRefer to any additional sections in the standard that are met, such as metatarsal (Mt) resistance and rating, conductive (Cd) properties, electrical hazard (EH), puncture resistance (PR), and static dissipative (SD) properties
Metatarsal: helps avoid or reduce the severity of injury to the metatarsal and toe areas
The existence of metatarsal resistance (Mt) and the rating (75, 50, or 30 foot-pounds) are identified.
Conductive: in a situation where the buildup of static electricity on the body is dangerous, it protects the wearer by driving static electricity away from the body into the ground
The range of electrical existence must be between zero and 500,000 ohms.
Electrical hazard: non-conductive electrical shock resistant soles and heels to provide additional protection against accidental contact with live electrical circuits, electrically engineered conductors, parts, or apparatus
Under dry conditions, it is able to endure the application of 14,000 volts at 60 hertz for one minute with no current flow or leakage current in excess of 3.0 milliamperes.
Static dissipative: reduces the accumulation of excess static electricity by conducting a body charge to ground it while keeping an adequately high level of resistance
Two types, both of which have a lower resistance limit of 106 ohms
Type I: electrical resistance of no more than 108 ohms, which is usually considered sufficient for semi-conductor applications
Type II: electrical resistance of no more than 109 ohms and has applications in work environments less demanding than Type I
The fourth line is used if more than three sections of the ANSI standard apply.


ASTM Requirements

Line 1: ASTM F2413-05
Indicates the ASTM standard
Signifies the performance requirements of ASTM F2413 issued in 2005 are met

Line 2: M I/75 C/75 Mt75
Indicates the gender [M (Male) or F (Female)] for which the footwear is intended
Shows the impact resistance (I), impact resistance rating (75 or 50 foot-pounds), compression resistance (C), compression resistance rating (75 or 50 which correlate to 2500 pounds and 1750 pounds of compression respectively), and metatarsal (Mt) rating (75 or 50 foot-pounds)

Lines 3 & 4: PR CS
Refer to any additional sections in the standard that are met, such as conductive (Cd) properties, electrical hazard (EH), puncture resistance (PR), static dissipative (SD) properties, chainsaw cut resistance (CS), and dielectric insulation (DI)
Conductive: protects against excess buildup of static electricity by assisting in electrical conductivity and transfer of excess static electricity from the body to the ground; decreases the chance of igniting explosives or volatile chemicals
The range of electrical existence must be between zero and 500,000 ohms.
Electrical hazard: non-conductive electrical shock resistant soles and heels to provide additional protection against accidental contact with live electrical circuits, electrically engineered conductors, parts, or apparatus
Under dry conditions, it is able to endure the application of 14,000 volts at 60 hertz for one minute with no current flow or leakage current in excess of 3.0 milliamperes.
Static dissipative: protects against the hazards of footwear with excessively low resistance, as well as keeps an adequately high level of resistance to lessen the risk of electrical shock
Requires an electrical resistance with a lower limit of 106 ohms and an upper limit of 108 ohms.
Puncture resistant: puncture resistant plate situated between the insole and outsole
Passes ASTM B117 Practice for Operating Salt Spray (Fog Apparatus) corrosion resistance test; after being exposed to a five percent salt solution for 24 hours, it must show no signs of corrosion, must have a minimum puncture resistance of 270 pounds, and must not show any signs of cracking after 1.5 million flexes.
Chainsaw cut resistant: protects the area of the foot between the toes and lower leg when using a chainsaw
Meets ASTM F1818 Specification for Foot Protection for Chainsaw Users standard.
Dielectric insulation: provides extra insulation in case of accidental contact with energized electrical conductors, devices, or circuits
Tested according to the ASTM F1116 (Text Method for Determining Dielectric Strength of Dielectric Footwear).
Meets ASTM F1117 (Specification for Dielectric Footwear) minimum requirement for insulation performance.
The fourth line is used if more than three sections of the ASTM standard apply.
