ISO 105-X12 Assessment of Color Fastness to Rubbing Under Dry Conditions

Comprehensive Guide to ISO 105-X12 Assessment of Color Fastness to Rubbing Under Dry Conditions Laboratory Testing Service

ISO 105-X12 is a widely recognized international standard that governs the assessment of color fastness to rubbing under dry conditions. This standard is published by the International Organization for Standardization (ISO) and is applicable to various industries, including textiles, leather, and paper.

Legal and Regulatory Framework

The ISO 105-X12 standard is based on a consensus-driven approach, involving input from experts in relevant fields. The standard has been developed to ensure that testing laboratories follow a consistent and reliable methodology for assessing color fastness to rubbing under dry conditions.

In many countries, compliance with ISO 105-X12 is mandatory for industries that produce or use colored materials. For example, the European Unions (EU) General Safety Regulation requires that all textiles sold in the EU meet specific safety standards, including those related to color fastness.

International and National Standards

ISO 105-X12 is a harmonized standard, meaning it has been adopted as an identical national standard by several countries. For example:

Standard Development Organizations

The development of ISO 105-X12 is overseen by the Technical Committee on Textiles (TC 38) and the Sub-Committee on Colorimetry (SC 1). These organizations ensure that the standard remains relevant and effective in meeting industry needs.

Evolution and Updates

Standards evolve over time to reflect changes in technology, regulations, or best practices. ISO 105-X12 is no exception. New versions of the standard are published periodically to incorporate updates and revisions.

For example, the latest version of ISO 105-X12 (2016) includes improved testing procedures for certain materials and updated reference values for color fastness assessments.

Standard Compliance Requirements

Compliance with ISO 105-X12 is essential for industries that produce or use colored materials. Non-compliance can lead to product recalls, damage to reputation, and financial losses.

Some examples of industries that require compliance with ISO 105-X12 include:
