Overview

ISO 105-A06:1995 is an international standard established by the International Organization for Standardization (ISO) for the instrumental determination of 1/1 standard depth of colour in textiles. This standard provides a reliable and objective colorimetric method as an alternative to the traditional visual assessments described in ISO 105-A01:1994. It is specifically designed to measure the depth of colour of dyeings on any textile material using precise instrument-based techniques.

The standard plays a critical role within the textile industry for testing and ensuring colour fastness and uniformity of dyed fabrics, supporting quality control and consistency in textile production.

Key Topics

Scope and Purpose The standard focuses on the 1/1 standard depth of colour and serves as an alternative method to visual evaluation, applicable to any textile material. It enhances accuracy by using instrumental colorimetry rather than subjective visual comparison.

Measurement Principles ISO 105-A06 measures the CIELAB colour coordinates:

L* (lightness)
C* (chroma)
h* (hue) The lightness difference between the measured fabric and the calculated 1/1 standard depth is determined to assess whether the specimen meets the standard.

Apparatus Required A spectrophotometer or colorimeter compliant with CIE Publication 15.2 is used to obtain precise colour data under standard observation conditions (10° observer, illuminant D65).

Specimen Preparation Test samples should be representative areas of the dyeing, cut to at least 50 mm x 50 mm, mounted on an opaque white backing without fluorescent whitening agents, and checked for opacity.

Test Procedure Multiple colorimetric readings are taken at different areas of the specimen to average out variations. The lightness difference (ΔL) calculated via the standard equation determines conformity to the 1/1 standard depth.

Reporting Requirements Test reports must include:

Reference to ISO 105-A06:1995
Detailed sample identification
Instrument type and configuration
Measured colour values
Test date

Applications

Textile Quality Control Ensures consistency in colour depth across production batches, critical for manufacturers aiming to meet customer and regulatory requirements regarding colour fastness.

Dye Development and Verification Supports dye manufacturers and textile processors in verifying dye concentration and shade reproducibility by providing an objective measure of colour depth.

Standardization of Colour Measurement Facilitates harmonized methods for colour testing internationally, reducing variability introduced by subjective visual assessments.

Compliance and Certification Assists in meeting industry standards and regulations related to textile colour performance, useful for certification bodies and laboratories conducting textile testing.
