ASTM F2412-24

1.1 These test methods measure the resistance of footwear to a variety of hazards that can potentially result in injury.

1.2 These test methods may be used to test for compliance to minimum performance requirements in established safety standards.

1.2.1 By agreement between the purchaser and the supplier, or as required by established safety standards, these test methods can be used to determine any one, or all of the following:

• (1) impact resistance (I),
• (2) compression resistance (C),
• (3) metatarsal impact resistance (Mt),
• (4) resistance to electrical conductivity (Cd),
• (5) resistance to electric hazard (EH),
• (6) static dissipative performance (SD), and
• (7) puncture resistance (PR).

1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 These test methods contain requirements to evaluate the performance of footwear for the following:

• 4.1.1 Impact resistance for the toe area of footwear (I),
• 4.1.2 Compression resistance for the toe area of footwear (C),
• 4.1.3 Metatarsal protection that reduces the chance of injury to the metatarsal bones at the top of the foot (Mt),
• 4.1.4 Conductive properties which reduce hazards that may result from static electricity buildup, and reduce the possibility of ignition of explosives and volatile chemicals (Cd),
• 4.1.5 Electric hazard to protect the wearer when accidentally stepping on live electric wires (EH),
• 4.1.6 Static dissipative properties to reduce hazards that result from a build up of static charge where there is an underlying risk of accidental contact with live electrical circuits (SD),
• 4.1.7 Puncture resistance footwear devices (PR).

4.2 Any changes to the original components of safety toe footwear such as replacing or adding after-market footbeds/inserts could cause non-compliance to any or all parts of this standard rendering the ASTM label invalid. Protective toe footwear specimens or samples shall be retested for any of the following changes.

• 4.2.1 Change in material used to make protective toe cap, change in protective cap manufacturer, change in the design of the toe cap.
• 4.2.2 Change in construction method used to make footwear or change in factory in which footwear is produced.
• 4.2.3 Change in the upper or insole material thickness greater than 25 %.
• 4.2.4 Change in the out sole or midsole, including its hardness.
• 4.2.5 Change in shape of last used in the manufacturing of footwear.
• 4.2.6 Change in material or supplier of protective insole.
• 4.2.7 Change in material or supplier of met guard.
