Key Takeaways
- EN 388:2016 uses A-F letter system (was 1-5 in 2003 version) based on ISO 13997 Newton scores
- TDM-100 test is more accurate than the old Coup Test for high-performance fibers
- Level A = 2-5 Newtons (lowest), Level F = 30+ Newtons (highest)
- Industry equivalent: EN 388 E ≈ ANSI/ISEA 105 A5
- Don't over-specify — higher levels reduce dexterity and increase cost
EN 388:2016 Cut Resistance Levels (A-F)
| Level | Newton Range | ANSI Equivalent | Typical Applications |
|---|---|---|---|
| A | 2-5 N | ANSI A1 | Light assembly, packaging, small parts |
| B | 5-10 N | ANSI A2 | Paper handling, light manufacturing |
| C | 10-15 N | ANSI A3 | Construction, material handling, automotive assembly |
| D | 15-22 N | ANSI A4 | Sheet metal, glass handling, HVAC |
| E | 22-30 N | ANSI A5 | Metal stamping, blade handling, glass manufacturing |
| F | 30+ N | ANSI A6-A9 | Meat processing, recycling, sharp blade operations |
What is a Newton (N)? A Newton is the force required to cut through the material with a standardized blade in a single pass. Higher numbers mean more cut resistance.
Understanding the EN 388 Code: XX.XX.X
The full EN 388 code has up to 6 positions. Here's how to read it:
Example: EN 388 4X43C
- Position 1 (4): Abrasion resistance — Level 4 of 4 (8,000+ cycles)
- Position 2 (X): Coup Test cut — Not performed (uses letter code instead)
- Position 3 (4): Tear resistance — Level 4 of 4 (75+ Newtons)
- Position 4 (3): Puncture resistance — Level 3 of 4 (60-100 Newtons)
- Position 5 (C): ISO 13997 cut resistance — Level C (10-15 Newtons)
- Position 6 (P): Impact protection — Optional (P = Pass)
EN 388:2003 vs 2016: What Changed?
Old Standard (2003)
- Cut test: Coup Test only (circular blade rotates back and forth)
- Cut rating: 1-5 numerical scale
- Problem: Blade dulls quickly on advanced fibers, making scores inconsistent above level 3
New Standard (2016)
- Cut test: Both Coup Test AND ISO 13997 (TDM-100)
- Cut rating: A-F letter scale (Newton-based)
- Improvement: TDM-100 uses a straight blade that doesn't dull, providing accurate scores for high-performance materials
Why two tests? If a glove scores 1-3 on the Coup Test, the letter code is reported. If it scores 4-5, the ISO 13997 letter is used. This dual approach ensures accuracy across all cut levels.
TDM-100 Test Method Explained
The TDM-100 (Tomodynamometer) test, standardized as ISO 13997, is the modern method for cut resistance testing:
- Sample Preparation: Glove material is cut into a 100mm × 50mm sample
- Blade: A straight sharp blade applies force perpendicular to the material
- Single Pass: Blade cuts through material in a single pass (no repeated motion)
- Measurement: The force (in Newtons) required to cut through is measured
- Result: Newton value determines A-F letter rating
Why TDM-100 is Better
- Consistent results across all material types
- Accurate for advanced fibers (HPPE, aramid, steel)
- Single-blade test (more realistic to actual cutting events)
- Better correlation with real-world cut hazards

Materials Used in Cut-Resistant Gloves
| Material | Cut levels | Properties | Best for |
|---|---|---|---|
| HPPE | A-D | Lightweight, flexible, moisture-resistant | General purpose cut resistance, comfort |
| Steel Wire Blends | D-F | Highest cut protection, slightly heavier | High cut hazards where dexterity is secondary |
| Composite Yarns | C-E | Balance of protection, dexterity, comfort | Most industrial applications |
| Aramid (Kevlar®) | B-D | Heat-resistant, good cut protection | Applications requiring both cut and heat resistance |
| Fiberglass | C-D | Good cut resistance, cost-effective in blends | Mid-range cut protection |
Common Mistakes to Avoid
1. Over-Specifying the Cut Level
Choosing level E when level C would suffice. Higher levels cost 2-3x more, reduce dexterity and comfort, and may cause workers to remove gloves — worse than no protection.
2. Ignoring Other Hazards
Cut resistance is only one part of EN 388. Also consider: Abrasion (position 1), Tear (position 3), Puncture (position 4).
3. Confusing EN 388 with ANSI/ISEA 105
These are two different standards. EN 388 uses A-F (European), ANSI uses A1-A9 (American). They're roughly equivalent but not identical.
4. Trusting Self-Reported Ratings
Always require: test reports from accredited labs (TÜV, SGS, BV, Intertek), CE certificate from EU-notified body, date of testing (within 3 years).
Testing & Certification
EN 388 testing must be performed by accredited laboratories. The certification process:
- Sample Selection: Multiple samples from production batch
- Pre-conditioning: Samples conditioned at 20°C/65% humidity for 24 hours
- Abrasion Test: EN 388:2016 Section 6.1 — Martindale method
- Cut Tests: Both Coup Test and ISO 13997 (TDM-100)
- Tear Test: EN 388:2016 Section 6.3 — Trouser-shaped sample
- Puncture Test: EN 388:2016 Section 6.4 — Steel stylus
- Report Issuance: Test report with all 6 positions
Cost: $1,500-3,000 per product for full EN 388 testing. Certificates valid 3-5 years depending on material changes.
