The Purpose of BS EN ISO 2556:2012
BS EN ISO 2556:2012 is a technical standard that sets out the requirements for determining the color fastness of textiles and textile products. This standard provides a reliable method to assess the colorfastness of fabrics, irrespective of their composition or use.
Colorfastness is an important characteristic of textiles as it ensures that the colors remain unchanged or fade within acceptable limits during use, washing, or exposure to light. The purpose of BS EN ISO 2556:2012 is to establish uniform testing procedures and rating systems to evaluate the color stability of textiles under various conditions.
Testing Methods and Criteria
BS EN ISO 2556:2012 specifies several testing methods to determine colorfastness, such as colorfastness to washing, to light, to rubbing, and to perspiration. These tests involve subjecting textile samples to specific conditions or agents to simulate real-life situations.
For example, the colorfastness to washing test evaluates the resistance of a fabric to color loss or transfer during repeated laundering. The colorfastness to light test assesses the fabric's ability to withstand fading caused by exposure to UV light. The colorfastness to rubbing test measures color transfer from one material to another through friction.
BS EN ISO 2556:2012 also defines grading systems to rate colorfastness performance. The ratings range from 1 (poor) to 5 (excellent), providing a standardized scale to classify the colorfastness properties of different textiles accurately.
The Importance of BS EN ISO 2556:2012
BS EN ISO 2556:2012 is essential in ensuring that textile products meet quality and safety requirements. By assessing colorfastness, manufacturers can guarantee that their products maintain their desired appearance throughout their lifespan.
Consumers also benefit from this standard as it allows them to make informed decisions when purchasing textiles. Understanding the colorfastness rating helps consumers choose products that best suit their needs, whether it's for apparel, home furnishings, or any other application.
BS EN ISO 2556:2012 has global recognition and harmonizes colorfastness testing methods and ratings internationally. This harmonization facilitates trade by ensuring consistent evaluation of textile products across different countries, thus promoting fair competition and consumer confidence.
