ISO 20344 Water Resistance and Breathability Testing for Microfiber Leather

Microfiber Leather Water Penetration and Water Vapour Permeability Testing

MICOOSON supplies microfiber synthetic leather materials for customers evaluating different product specifications and performance requirements.

For footwear material buyers, water penetration, water absorption and water vapour permeability are important characteristics when selecting upper materials.

MICOOSON has third-party test documentation for a submitted black microfiber material evaluated under ISO 20344:2011.

The report records Pass conclusions for the specified water penetration, water absorption and water vapour permeability requirements.

What Is ISO 20344 Testing?

ISO 20344 establishes test methods for evaluating specified properties of footwear and footwear components.

The submitted microfiber sample was tested using ISO 20344:2011 methods covering:

  • Water Penetration and Water Absorption (Upper)

  • Water Vapour Permeability

  • Water Vapour Coefficient

These tests provide material performance information under defined laboratory conditions.

A material test report does not automatically establish that a finished safety shoe has achieved S2 classification or certification.

Microfiber Leather Test Report Information

The laboratory test report identifies the following information:

  • Report Number: SL92309277187301FW

  • Report Date: May 5, 2023

  • Sample Description: MICROFIBER

  • Sample Color: Black

  • Test Method: ISO 20344:2011

  • Water Penetration and Absorption Method: Section 6.13

  • Water Vapour Test Methods: Sections 6.6, 6.7 and 6.8

  • Overall Conclusions: PASS for both reported test categories

The testing information applies to the submitted sample and specified laboratory conditions.

Water Penetration and Water Absorption Test Results

Water penetration testing assesses the amount of water passing through a material under the specified test method.

Water absorption testing evaluates the water absorbed by the tested material.

The report records the following results:

  • Water Absorption: 6.8%

  • Reported Requirement: Maximum 30.0%

  • Water Penetration: 0.02 g

  • Reported Requirement: Maximum 0.2 g

  • Test Conclusion: PASS

These values indicate that the submitted microfiber sample met the stated water penetration and absorption requirements.

The results do not mean that every microfiber leather grade or finished footwear product is completely waterproof.

Water Vapour Permeability and Coefficient Results

Water vapour permeability is an important property when evaluating moisture transfer through footwear upper materials.

The report records:

  • Water Vapour Permeability (WVP): 2.03 mg/(cm²·h)

  • Minimum WVP Requirement: 0.8 mg/(cm²·h)

  • Water Vapour Coefficient (WVC): 18 mg/cm²

  • Minimum WVC Requirement: 15 mg/cm²

  • Test Conclusion: PASS

The documented water vapour tests were performed at (23 ± 2)°C and (50 ± 5)% relative humidity.

The report also specifies 20,000 Bally flexing cycles as pretreatment, a one-hour pre-run period and an eight-hour test period.

These findings apply to the tested microfiber sample and should not be interpreted as complete breathability performance of a finished shoe.

Why Are Water Resistance and Breathability Important for Footwear Materials?

Footwear upper materials may need to balance resistance to water penetration with the ability to transfer water vapour.

When evaluating microfiber synthetic leather for footwear applications, material buyers should consider:

  • Water penetration test results

  • Water absorption performance

  • Water vapour permeability

  • Water vapour coefficient

  • Material thickness and construction

  • Surface treatment and backing structure

  • Intended footwear application

  • Required test methods

  • Customer-specific performance requirements

Finished footwear performance also depends on the overall shoe design, construction, seams and other components.

Is ISO 20344 Testing the Same as S2 Safety Footwear Certification?

No.

ISO 20344 specifies test methods used to evaluate footwear and footwear components.

S2 is a classification associated with applicable safety footwear requirements, and determining the classification of a finished shoe involves additional criteria.

The SGS test report for the submitted MICOOSON microfiber sample documents the specific upper material tests performed. It does not certify a finished shoe as S2.

Frequently Asked Questions

Does MICOOSON Have ISO 20344 Testing Documentation for Microfiber Leather?

Yes. MICOOSON has a third-party test report for a submitted black microfiber sample evaluated under ISO 20344:2011.

What Was the Water Penetration Test Result?

The reported water penetration value was 0.02 g against a stated maximum requirement of 0.2 g.

What Was the Water Absorption Test Result?

The report recorded water absorption of 6.8%, compared with the stated maximum requirement of 30.0%.

What Was the Water Vapour Permeability Result?

The report recorded a WVP value of 2.03 mg/(cm²·h), above the stated minimum requirement of 0.8 mg/(cm²·h).

What Was the Water Vapour Coefficient Result?
