ISO 5402 Leather Determination of Grain Crack Resistance Laboratory Testing Service Provided by Eurolab

Standard-Related Information

The determination of grain crack resistance is a critical test for leather manufacturers, suppliers, and users to ensure the quality and performance of their products. The International Organization for Standardization (ISO) has developed a standard for this purpose, ISO 5402:2013, which specifies the method for determining the resistance to cracking of leathers.

Legal and Regulatory Framework

The legal and regulatory framework surrounding leather testing is governed by various international and national standards. In Europe, the European Unions (EU) directives and regulations are enforced through the CE marking, which indicates compliance with EU legislation. The EU has established specific regulations for leather products, such as the EU regulation on non-human primates in cosmetics (Regulation 1223/2009), which includes requirements for leather testing.

International and National Standards

The following international and national standards apply to ISO 5402 Leather Determination of Grain Crack Resistance testing:

  • ISO 5402:2013

  • ASTM D1308-10

  • EN ISO 5402:2013

  • TSE ISO 5402:2013 (Turkish Standard)

  • Industry-specific standards, such as Oeko-Tex and Bluesign

    • Standard Development Organizations

    The standard development organizations involved in the creation of ISO 5402 include:

  • International Organization for Standardization (ISO)

  • American Society for Testing and Materials (ASTM)

  • European Committee for Standardization (CEN)

    • These organizations work together to develop, maintain, and promote standards that ensure consistency, quality, and safety in various industries.

    Standard Evolution and Update

    Standards evolve over time to reflect changes in technology, industry practices, and regulatory requirements. New editions of standards are developed through a formal process, which involves review, revision, and approval by the relevant standard development organizations.

    Specific Standard Numbers and Scope

    The following standard numbers and scope apply to ISO 5402:

  • ISO 5402:2013 Determination of Grain Crack Resistance

    • Applies to leathers used for various applications, including clothing, upholstery, and industrial purposes

    Standard Compliance Requirements

    Different industries have specific requirements for standard compliance. For example:

  • Textile industry: EN 13523-8:2004
