What is EN ISO 105-K02:1993?

The EN ISO 105-K02:1993 is a technical standard that provides guidelines and specifications for testing the colorfastness of textiles against artificial light sources. This standard is part of the European Norm (EN) series and has been adopted by the International Organization for Standardization (ISO), making it an internationally recognized industry benchmark.

Importance of Colorfastness Testing

Colorfastness testing plays a crucial role in the textile industry as it helps manufacturers, retailers, and consumers determine how well a fabric retains its original color when exposed to various environmental factors such as sunlight, washing, and friction. By adhering to the EN ISO 105-K02:1993 standard, textile companies can ensure that their products meet the desired quality and durability requirements.

The Testing Procedure

The EN ISO 105-K02:1993 standard outlines a precise and comprehensive procedure for conducting colorfastness tests on textiles. The test involves subjecting the sample fabric to specific levels of artificial light radiation for predetermined durations, simulating real-world conditions. The colorfastness is then evaluated by visually comparing the original and tested samples using a set of predefined criteria.

Understanding the Test Results

The test results obtained through the EN ISO 105-K02:1993 procedure are typically provided as a numerical rating. This rating indicates the level of colorfastness achieved by the fabric under test. Higher ratings indicate better colorfastness, implying that the fabric is less likely to fade or change color significantly when exposed to artificial or natural light sources over time.
