How EN388 Testing Is Performed (Factory Perspective)

How EN388 Testing Is Performed (Factory Perspective)

For buyers of cut resistant gloves, the EN388 standard is often seen only as a label printed on the glove. However, behind that label is a detailed laboratory testing process designed to measure how well gloves protect against mechanical hazards.

From a manufacturer's perspective, understanding how EN388 testing is performed is essential for ensuring consistent product quality and certification compliance.

In this article, we explain the complete EN388 testing process from the factory point of view.

What Is EN388 Testing?

EN388 is a European safety standard used to evaluate gloves that protect against mechanical risks.

The standard measures five main types of protection:

Abrasion resistance

Blade cut resistance

Tear resistance

Puncture resistance

Impact protection (optional)

A typical EN388 marking looks like this:

EN388: 4X43D

Each character represents a performance level obtained during laboratory testing.

 

Step 1: Sample Preparation

Before testing begins, glove samples must be carefully prepared according to laboratory requirements.

Preparation typically includes:

Cutting test pieces from the glove palm area

Conditioning samples at controlled temperature and humidity

Preparing multiple specimens to ensure consistent results

Most manufacturers send samples to certified laboratories such as:

SGS

Intertek

TÜV

Testing multiple samples ensures the results accurately represent the glove's overall material performance.

 

Step 2: Abrasion Resistance Test

The abrasion test measures how resistant the glove material is to surface wear.

Testing procedure:

A circular sample of glove material is mounted on a testing machine.

Sandpaper rotates against the material under constant pressure.

The machine counts the number of cycles until the material breaks.

Performance levels are rated as follows:

 

Level	Abrasion Cycles
1	100 cycles
2	500 cycles
3	2000 cycles
4	8000 cycles

Industrial safety gloves commonly achieve Level 3 or Level 4.

 

Step 3: Coupe Blade Cut Test

The traditional EN388 cut resistance test is called the Coupe Test.

Testing process:

A circular blade moves back and forth across the glove material.

The blade continues until it cuts through the sample.

The number of cycles required is compared to a reference material.

 

However, this test has limitations when testing high-performance fibers such as:

HPPE

Aramid

Steel fiber blends

These materials can dull the blade, which may lead to inaccurate results.

 

Step 4: ISO 13997 TDM Cut Test

To improve accuracy, modern cut-resistant gloves are also tested using the ISO 13997 TDM test.

Testing procedure:

A straight blade presses down on the glove sample.

The machine gradually increases force.

The force required to cut through the material is recorded.

Results are measured in Newtons (N).

Performance levels are classified as:

 

Level	Cut Resistance
A	≥ 2N
B	≥ 5N
C	≥ 10N
D	≥ 15N
E	≥ 22N
F	≥ 30N

 

Examples:

Food processing gloves: Level C–D

Glass handling gloves: Level E

Heavy metal industry: Level F

 

Step 5: Tear Resistance Test

The tear resistance test measures how much force is needed to tear the glove material.

Testing process:

The sample is clamped into a tensile testing machine.

The machine pulls the material in opposite directions.

The force required to tear the sample is measured.

Materials with strong fiber structures, such as HPPE and Kevlar, usually perform well in this test.

 

Step 6: Puncture Resistance Test

The puncture test evaluates resistance to sharp objects.

Testing method:

A steel probe presses into the glove material.

The machine measures the force required to puncture the sample.

This simulates hazards such as:

Metal shards

Nails

Sharp industrial tools

Industries like construction, metal fabrication, and recycling rely heavily on gloves with high puncture resistance.

 

Step 7: Impact Protection Test (Optional)

Some industrial gloves include TPR impact protection.

If so, an additional impact test is performed.

Testing method:

A weight is dropped onto the glove's protective area.

Sensors measure the amount of force transmitted through the glove.

If the glove passes the test, it receives the "P" marking.

Example:

EN388: 4X43DP

 

Why EN388 Testing Matters for Buyers

From a factory perspective, EN388 testing plays a critical role in maintaining product reliability.

For buyers, EN388 ratings help:

Compare gloves from different manufacturers

Verify cut resistance performance

Ensure workplace safety compliance

Reduce injury risks

For manufacturers, consistent EN388 performance depends on:

high-quality yarn materials

precise knitting density

reliable coating technology

strict production quality control

 

Conclusion

EN388 testing provides a standardized and reliable method for evaluating protective gloves used in industrial environments.

While the EN388 rating printed on a glove may look simple, it represents a detailed series of laboratory tests designed to ensure safety and durability.

Understanding how EN388 testing works allows buyers to select gloves that provide the right level of protection for their specific applications.

 

FAQ 

What does EN388 mean on gloves?

EN388 is a European standard that measures a glove's resistance to mechanical risks such as abrasion, cuts, tears, and punctures.

 

What is a good EN388 rating?

For most industrial applications, gloves rated 4X43D or higher provide strong mechanical protection.

 

What is the difference between the Coupe test and the TDM test?

The Coupe test measures blade cut resistance using repeated blade movement, while the TDM test measures the force required to cut through the material.

The TDM test is more accurate for modern high-performance fibers.
