While ASTM standards provide a baseline for testing slip resistance in footwear, some brands go beyond these requirements by testing against more extreme or unconventional contaminants. These additional tests help ensure superior performance in real-world environments where conditions may be harsher than standard testing scenarios. Grease is one example, but other contaminants might include industrial oils, food-grade lubricants, or even mixed wet/dry conditions. Brands that exceed ASTM standards often aim to provide enhanced safety assurances for workers in high-risk industries like food processing, manufacturing, or healthcare.
Key Points Explained:
-
Grease as an Extreme Contaminant
- ASTM standards typically test slip resistance on surfaces like water, glycerin, or soap solutions.
- Grease is more challenging due to its viscosity and adhesion properties, making it a tougher test for footwear.
- Brands that test against grease and still achieve a coefficient of friction (COF) of 0.40 or higher demonstrate superior traction performance.
-
Other Potential Contaminants Beyond ASTM Standards
- Industrial Oils: Heavy machinery and automotive environments often involve exposure to hydraulic or motor oils, which can be more slippery than standard test liquids.
- Food-Grade Lubricants: In food processing, workers encounter vegetable oils, animal fats, or food-grade lubricants, which may not be covered in ASTM tests.
- Mixed Contaminants: Real-world conditions often involve combinations (e.g., water + oil), which can be more hazardous than single-contaminant ASTM tests.
- Chemicals & Solvents: Some workplaces use strong solvents or cleaning agents that alter surface friction unpredictably.
-
Why Brands Exceed ASTM Standards
- Higher Safety Assurance: Testing against tougher contaminants ensures footwear performs well in unpredictable workplace conditions.
- Competitive Differentiation: Brands that go beyond ASTM can market their products as premium or industry-specific solutions.
- Regulatory & Liability Considerations: Some industries or insurers may require additional testing to mitigate slip-and-fall risks.
-
Implications for Purchasers
- When selecting footwear, buyers in high-risk industries should look for brands that test against contaminants relevant to their specific work environment.
- A COF of 0.40 or higher on extreme contaminants indicates a stronger slip-resistant design.
- ASTM compliance is a minimum—brands that exceed it often provide better long-term value in safety-critical roles.
By understanding these additional testing practices, purchasers can make more informed decisions about footwear that truly meets their workplace demands.
Summary Table:
| Contaminant Type | Why It Matters | Industries Affected |
|---|---|---|
| Grease | Higher viscosity and adhesion make it harder to maintain traction. | Automotive, Manufacturing |
| Industrial Oils | More slippery than standard test liquids, common in machinery-heavy workplaces. | Construction, Oil & Gas |
| Food-Grade Lubricants | Not covered by ASTM but prevalent in food processing environments. | Food Processing, Hospitality |
| Mixed Wet/Dry Conditions | Real-world hazards often involve combinations (e.g., water + oil). | Healthcare, Warehousing |
| Chemicals & Solvents | Can unpredictably alter surface friction, posing unique slip risks. | Laboratories, Cleaning Services |
