The key difference in ASTM F2413-18 vs ASTM F2413-24 is that F2413-24 updates the specification to reflect current testing and footwear requirements and formally incorporates slip-resistance classifications. Under F2413-24, SR identifies slip-resistant performance, while SRO identifies slip resistance for oily-wet conditions. These classifications reference ASTM F3445 testing.
For companies purchasing new safety shoes in 2026, F2413-24 should generally be the starting point when the applicable specification calls for the current ASTM edition. Understanding ASTM F2413-18 vs ASTM F2413-24 helps buyers avoid outdated language in purchase orders.
What Is ASTM F2413?
Content Nav
ASTM F2413 sets the minimum performance requirements for protective toe-cap footwear in the United States. OSHA references it under 29 CFR 1910.136. The companion document ASTM F2412 describes the laboratory test methods. Together they form the backbone of modern safety shoes standards.
Every certified pair must pass impact and compression tests on the toe. Additional optional ratings cover metatarsal protection (Mt), electrical hazard (EH), puncture resistance (PR), static dissipative (SD), and conductive (Cd) properties. Labels list the edition year and the protection codes the pair actually meets. When teams review ASTM F2413-18 vs ASTM F2413-24, these core protections stay consistent across both editions.
ASTM F2413-18 vs ASTM F2413-24: Side-by-Side Comparison
| Area | ASTM F2413-18 | ASTM F2413-24 |
|---|---|---|
| Slip resistance | Not formally part of the specification | SR and SRO designations added via ASTM F3445-21 |
| Gender / sizing language | Men’s (M) and Women’s (F) only | Unisex (U) definitions added |
| Definitions | Standard wording | Updated for current materials and construction |
| Labeling | Established multi-line format | Minor refinements for clearer reading |
| Test-method alignment | Linked to the 2018-era F2412 | Updated to the current F2412 revisions |
| Status in 2026 | Previous edition | Current edition |
This table highlights the key differences between ASTM F2413-18 and ASTM F2413-24. Although these changes may seem minor on paper, they are critical in procurement and personal protective equipment (PPE) projects. Anyone comparing ASTM F2413-18 vs ASTM F2413-24 can use this table as a quick reference.
What Changed from ASTM F2413-18 to ASTM F2413-24?
1. Slip Resistance Became a Formal Part of the Specification
The largest practical difference in ASTM F2413-18 vs ASTM F2413-24 sits in slip resistance. Before 2024 a manufacturer could claim “slip resistant” without a standardized test inside the F2413 framework. F2413-24 formally incorporates SR (coefficient of friction ≥ 0.40 on wet and dry quarry tile) and SRO (the same plus ≥ 0.33 on oily-wet surfaces). Those numbers come from ASTM F3445-21. In high-spill environments—food plants, oil and gas, warehouses—the SR or SRO mark now carries real weight. This shift is the most discussed point in ASTM F2413-18 vs ASTM F2413-24 conversations.
2. Unisex sizing standards have been introduced
Many safety shoes factory had already been building unisex lasts. The 2024 text simply codified the language so labels can show “U” instead of forcing a men’s or women’s designation. Buyers reviewing ASTM F2413-18 vs ASTM F2413-24 often note this practical improvement for inventory management.
3. Updated References and Terminology
Definitions received a quiet update to reflect today’s composite toes, thermoplastic outsoles, and construction methods. Labeling got small clarity tweaks. Test methods were aligned with the latest F2412 revisions so labs and manufacturers stay in sync.
None of these shifts overturn the impact or compression numbers. A pair that passed under F2413-18 still protects the foot the same way. The update mainly improves consistency and gives buyers clearer language for slip performance. These refinements define the real-world impact of ASTM F2413-18 vs ASTM F2413-24.
ASTM F2413-24 Protection Categories Explained
Understanding the markings is more useful than memorizing the edition number.
| ASTM F2413-24 Marking / Category | What It Means | Main Protection / Hazard | Typical Applications |
|---|---|---|---|
| I/C – Impact & Compression | Protects the toe area against impact and compression hazards | Falling objects, crushing forces, heavy equipment | Construction, manufacturing, warehousing, mining |
| Mt – Metatarsal Protection | Protects the metatarsal bones on the top of the foot | Heavy objects or equipment striking the upper foot | Construction, foundries, manufacturing, heavy industry |
| EH – Electrical Hazard | Provides electrical-shock resistance under specified test conditions | Certain electrical shock hazards | Construction, electrical work, maintenance, utilities |
| PR – Puncture Resistance | Helps resist penetration through the bottom of the footwear | Nails, screws, sharp metal, debris | Construction, demolition, roofing, manufacturing |
| SD – Static Dissipative | Controls static buildup through controlled electrical resistance | Electrostatic discharge and static accumulation | Electronics, manufacturing, pharmaceutical, cleanroom environments |
| Conductive | Allows controlled dissipation of static electricity through the footwear | Static buildup where conductive footwear is appropriate | Specialized manufacturing and environments requiring static control |
| Chainsaw-Cut Protection | Provides protection against specified chainsaw-cut hazards | Chainsaw contact and cutting hazards | Forestry, logging, tree care, wood processing |
| Dielectric Insulation | Provides specialized electrical insulation under applicable test conditions | Specific electrical hazards requiring dielectric protection | Electrical utilities and specialized industrial applications |
Is ASTM F2413-18 Still Valid?
Yes. In my experience across dozens of 2025 and 2026 audits, existing pairs marked ASTM F2413-18 continue to satisfy most written PPE programs and OSHA expectations. The standard does not automatically invalidate prior certifications when a new edition appears. Many companies still rely on astm f2413 18 boots that remain in good condition.
That said, many large buyers and safety shoes supplier contracts now write “ASTM F2413-24 or latest edition.” If your purchase order or corporate standard still references only the 2018 text, update it. New production from reputable safety shoes manufacturers already carries the 2024 mark. This remains one of the most practical questions in ASTM F2413-18 vs ASTM F2413-24 discussions.
ASTM F2413-18 vs ASTM F2413-24: Which One Should You Choose?
For boots already on workers’ feet or sitting in the cage, ASTM F2413-18 remains fine. For every new order, specify ASTM F2413-24 and the exact protection codes your hazard assessment requires. If slip resistance is part of that assessment, demand the SR or SRO rating.
The practical advice stays simple: match the edition to the life stage of the footwear.
When you weigh ASTM F2413-18 vs ASTM F2413-24 for a multi-year contract, lean toward the current edition. It future-proofs the purchase and aligns with the direction most safety shoes standards are moving. Choosing correctly in ASTM F2413-18 vs ASTM F2413-24 decisions protects both workers and compliance records.
