Accredited methods

Water Absorption and Desorption

ISO 22649 Footwear — Test methods for insoles and insocks — Water absorption and desorption
This standard specifies two test methods for determining the water absorption and desorption of insoles and insocks, irrespective of the material:
Method A: Determination of the static water absorption and desorption of insoles and insocks.
Method B: Determination of the dynamic water absorption and desorption of insoles and insocks.

ISO 20344 (Art. 7.2) Personal protective equipment — Test methods for footwear
This standard specifies methods for testing footwear designed as personal protective equipment.
7.2 Determination of water absorption and desorption of insole and insock

Water Resistance of Heavy Leather

ISO 5404 Leather — Physical test methods — Determination of water resistance of heavy leathers
This standard specifies a method for determining the water resistance of heavy leathers. The method allows determination of the penetration time, water absorption, area of penetration and water penetration rate as required. It is applicable to all types of heavy leathers.

Abrasion Resistance – cylindrical drum device

ISO 4649 Rubber, vulcanized or thermoplastic — Determination of abrasion resistance using a rotating cylindrical drum device
This standard specifies two methods for the determination of the resistance of rubber to abrasion by means of a rotating cylindrical drum device:
Method A is for a non-rotating test piece.
Method B is for a rotating test piece.
The methods involve determination of the volume loss due to the abrasive action of rubbing a test piece over a specified grade of abrasive sheet. For each method, the result can be reported as a relative volume loss (Vrel)  or an abrasion resistance index (ARI).
These test methods are suitable for comparative testing, quality control, specification compliance testing, referee purposes and research and development work. No close relation between the results of this abrasion test and service performance can be inferred.

ISO 20871 Footwear — Test methods for outsoles — Abrasion resistance
This standard specifies a method for the determination of the abrasion resistance for outsoles, irrespective of the material.

ČSN 62 1466 (621466) Rubber. Determination of abrasion resistance using a rotating cylindrical drum device
This Czech standard (mod ISO 4649:1985) is valid in the Czech Republic.

Flex Resistance

ISO 17694 Footwear — Test methods for uppers and lining — Flex resistance
This standard specifies a test method for determining the flex resistance of uppers and linings irrespective of the material in order to assess the suitability for the end use.

ISO 5402-1 (IULTCS/IUP 20) Leather — Determination of flex resistance — Part 1: Flexometer method – without Art. 5.10
This international standard specifies a method for determining the wet or dry flex resistance of leather and finishes applied to leather. It is applicable to all types of flexible leather below 3,0 mm in thickness.

Water Vapor Permeability and Absorption

ISO 17699 Footwear — Test methods for uppers and lining — Water vapour permeability and absorption
This standard specifies two test methods for assessing:
water vapour permeability (WVP)
water vapour absorption (WVA)
of uppers or complete upper assembly irrespective of the material, in order to assess the suitability for the end use.

ISO 20344 (Art. 6.6 and Art. 6.7 ) Personal protective equipment — Test methods for footwear
This standard specifies methods for testing footwear designed as personal protective equipment.
6.6 Determination of water vapour permeability (WVP)
6.7 Determination of water vapour absorption (WVA)

Abrasion Resistance – Martindale method

 EN 13520 Footwear – Test methods for uppers, lining and insocks – Abrasion resistance
This standard specifies a test method for determining the resistance of uppers, linings and insocks irrespective of the material, to wet and dry abrasion, in order to assess the suitability for the end use.

ISO 17704 Footwear — Test methods for uppers, linings and insocks — Abrasion resistance
This European standard specifies a test method for determining the resistance of uppers, linings and insocks irrespective of the material, to wet and dry abrasion, in order to assess the suitability for the end use.

ISO 20344 (Art. 6.12) Personal protective equipment — Test methods for footwear
This standard specifies methods for testing footwear designed as personal protective equipment.
6.12 Determination of abrasion resistance of lining and insock

ISO 12947-2 Textiles — Determination of the abrasion resistance of fabrics by the Martindale method — Part 2: Determination of specimen breakdown
This standard specifies the procedure for the determination of specimen breakdown (end-point of test) by inspection at fixed intervals and is applicable to all textile fabrics including nonwovens apart from fabrics where the specifier indicates the end performance as having a low abrasion wear life. It is not applicable to coated fabrics (including laminated fabrics).

ISO 20868 Footwear — Test methods for insoles — Abrasion resistance
This standard specifies a test method to determine the abrasion resistance of insoles, irrespective of the material.

Surface Fuzzing and Pilling – Modified Martindale method

ISO 12945-2 Textiles — Determination of fabric propensity to surface fuzzing and to pilling — Part 2: Modified Martindale method
This part of ISO 12945 specifies a method for determination of the resistance to pilling and surface change of textile fabrics using a modified Martindale method.

Color Fastness 

ISO 11640  (IULTCS/IUF 450) Leather — Tests for colour fastness — Colour fastness to cycles of to-and-fro rubbing – without Art. 4.8
This standard specifies a method for determining the behaviour of the surface of a leather on rubbing with a wool felt. It is applicable to leathers of all kinds.

ISO 17700 Footwear — Test methods for upper components and insocks — Colour fastness to rubbing and bleeding – without Method A
This standard specifies two test methods (method A and method B) for assessing the degree of damage (marring) and transfer of a material’s surface colour during mild dry or wet abrasion. The methods are applicable to all footwear uppers, linings and insocks irrespective of the material, in order to assess suitability for end use.
This standard also specifies a method (method C) for determining the likelihood of colour bleeding from materials and components such as sewing threads and shoe laces due to the action of water and artificial perspiration solutions, in order to assess suitability for end use.
