3.1 Safety gloves classification
Types of PPE hand gloves used in industry
Cut-resistant gloves:
- Designed for handling sharp metal, glass, blades, and tools
- Made from high-strength fibers like Kevlar, HPPE, or steel mesh blends
- Provide graded protection levels (EN 388 cut rating) based on risk
- Used in fabrication, maintenance, packaging, and material handling
- Balance between cut protection and finger dexterity is important
What is EN 388 Cut Rating?
EN 388 is a European standard that evaluates how well protective gloves resist mechanical hazards like cuts, abrasion, tearing, and puncture.
It’s widely used in industries such as manufacturing, pharma, and construction to select the right hand protection.
- Always focus on E (A–F cut rating) for modern gloves
- Higher rating = better protection, but may reduce flexibility
- Choose based on actual hazard (sharp edges, glass, sheet metal)
- EN 388 does not cover chemical or heat protection
EN 388:2016 Rating Format
The rating is shown under a shield icon like this:
EN 388: ABCDEF
Each letter/number represents a test:
| Code | Property Tested | Rating Range | Meaning |
|---|---|---|---|
| A | Abrasion Resistance | 0–4 | Higher = more durable surface |
| B | Cut Resistance (Blade) | 0–5 | Circular blade test |
| C | Tear Resistance | 0–4 | Resistance to tearing |
| D | Puncture Resistance | 0–4 | Resistance to sharp objects |
| E | Cut Resistance (ISO 13997) | A–F | Most important for high-cut risks |
| F | Impact Protection | P (Pass) / X | Optional test |
Cut Resistance tests
There are 2 cut tests:
1. Blade Cut (Coup) Test (B: 0–5)
- Uses a rotating circular blade
- Can be inaccurate for modern high-strength fibers
- Methodology: A rotating circular blade (Coup test) moves horizontally across the fabric, while the blade also rotates, cutting through the material.
- Control Fabric: The number of cycles to cut through the sample is compared to a cotton control fabric to calculate a cut resistance index.
- Replacement: A new blade is used for each test to ensure accuracy.
- Limitations: This method is best suited for materials that do not dull the blade. For high-performance materials (e.g., Kevlar, glass fiber), the EN ISO 13997 test (rated A–F) is now mandatory under EN 388:2016.
- Levels 1-2: Suited for packaging, assembly, and light manufacturing.
- Levels 3-4: Suitable for general handling, construction, and automotive work.
- Level 5: Required for high-risk, heavy-duty applications like metal fabrication and glass handling.
2. ISO Cut Test (EN 388 – E Rating: A–F)
The ISO Cut Test (ISO 13997) is the most accurate method used in EN 388:2016 to measure how resistant a glove is to cuts, especially for modern high-strength materials like HPPE, aramid (Kevlar), or steel fiber.
How the ISO Cut Test Works
- A straight blade is drawn once across the glove material
- The test measures the force (in Newtons, N) required to cut through the fabric
- Higher force means better cut resistance
- Unlike the coup test, results are not affected by blade dulling
Why ISO Test is Important
- More reliable than the older coup test (0–5 scale)
- Suitable for modern cut-resistant materials
- Used when the blade test result is marked as “X”
- Provides realistic performance under actual cutting hazards
Example EN 388 Marking
- Focus on the A–F rating for cut hazards
- Higher level provides better protection but may reduce flexibility
- Selection should be based on task, hazard level, and comfort requirements
