International standards are at the core of achieving and demonstrating reliable textile quality. For businesses—ranging from fashion brands to industrial textiles, laundries, and specialist suppliers—adhering to well-established specifications for textile colour fastness directly translates into enhanced competitiveness, fewer returns, and stronger consumer trust.

In this article, you’ll discover:

• What each international colour fastness standard covers
• Key testing requirements and why they matter
• Industry best practices for compliance
• How these standards benefit productivity and market access
• Practical steps for adopting textile standards at your organization

Whether you’re a manufacturer looking to enter new markets, a retailer checking supply chain quality, or simply interested in how textiles are tested for reliability, this guide delivers the insights you need.

Detailed Standards Coverage

SIST EN ISO 105-A01:1996 - General Principles of Colour Fastness Testing

Textiles – Tests for colour fastness – Part A01: General principles of testing (ISO 105-A01:1994)

This foundational standard establishes the basic concepts that underpin all colour fastness testing in the textile industry. It describes general principles, definitions, and test procedures that ensure results are reproducible and meaningful across the global supply chain.

The scope of SIST EN ISO 105-A01:1996 includes:

• Framework for standardizing all colour fastness test methods
• Guidelines for test specimen preparation, test environment, and reporting
• Harmonized terminology to support unambiguous communication among stakeholders

Key requirements:

• Consistent preparation of textile test samples
• Defined atmospheric and procedural parameters
• Reporting protocols for results interpretation

Who needs this standard?

• All textile manufacturers, laboratories, quality control units, and suppliers involved in producing or testing dyed, printed, or finished fabrics.

Practical implications include a streamlined testing workflow, minimized errors, and readiness for specific fastness tests (like to light or washing).

Key highlights:

• Provides the backbone for all subsequent colour fastness tests
• Defines environmental controls crucial for test accuracy
• Ensures comparability of results between different labs or suppliers

SIST EN ISO 105-B02:1999 - Colour Fastness to Artificial Light (Xenon Arc Fading Lamp Test)

Textiles – Tests for colour fastness – Part B02: Colour fastness to artificial light: Xenon arc fading lamp test (ISO 105-B02:1994, including amendment 1:1998)

SIST EN ISO 105-B02:1999 is the benchmark for evaluating how textile colours hold up when exposed to artificial light. Using xenon arc lamps that mimic natural daylight, this standard helps predict how easily fabrics might fade in store displays, domestic interiors, or outdoor applications.

Scope and purpose:

• Covers testing of all textile types (dyed, printed, bleached, or optically brightened) for resistance to daylight-equivalent artificial light.
• Simulates real-world fading scenarios, using blue wool references to provide objective benchmarking.
• Ensures consistent results regardless of where or how the test is performed, thanks to strict apparatus and humidity controls.

Specifications and requirements:

• Exposure of test specimens alongside blue wool references in a xenon arc lamp apparatus.
• Control of temperature, humidity, and light intensity to mirror natural conditions.
• Assessment of colour change using internationally accepted grey scales.

Who should use this standard?

• Apparel and home textiles manufacturers
• Furnishing and automotive textile suppliers
• Testing laboratories with a focus on colour durability
• Retailers and brands promising lasting product quality

By implementing this xenon arc lightfastness test, companies can proactively manage claims about product durability and meet legal or labeling requirements for both domestic and export markets.

Key highlights:

• Highly repeatable method for assessing fading from daylight
• Applicable to all types of textiles, including optically brightened whites
• Supports global trade with harmonized reference materials

SIST EN ISO 105-C06:1999 - Colour Fastness to Domestic and Commercial Laundering

Textiles – Tests for colour fastness – Part C06: Colour fastness to domestic and commercial laundering (ISO 105-C06:1994)

Washing is one of the most common stressors for textiles. This standard specifies robust test methods to simulate both domestic laundry cycles and the harsher washing conditions encountered in commercial settings (such as hotels or hospitals).

Scope:

• Describes procedures that mimic standard laundry operations, from detergent types to machine agitation and temperature cycles.
• Includes protocols for multi-fibre companion fabrics to gauge colour transfer and staining risk during washing.

Key requirements:

• Defined washing regimes: temperature, time, detergent, mechanical action
• Measurement of colour change and staining using grey scales
• Separate procedures for domestic (home) and commercial laundering

Who benefits from this standard?

• Home textile suppliers
• Laundry services and facilities
• Uniform, workwear, and hospital textile producers
• Quality assurance teams

By standardizing laundry resistance testing, companies can significantly reduce complaints due to fading, bleeding, or unexpected changes after repeated washes.

Key highlights:

• Reflects everyday real-life washing processes
• Essential for claims of wash durability or “machine washable” labels
• Helps ensure lasting satisfaction for consumers and institutional buyers

SIST EN ISO 105-X12:1996 - Colour Fastness to Rubbing

Textiles – Tests for colour fastness – Part X12: Colour fastness to rubbing (ISO 105-X12:1993)

Rubbing, or “crocking,” is a frequent cause of unwanted colour transfer from textiles onto other materials—jeans staining seats or garments marking accessories, for example. This standard delivers a repeatable method to evaluate how well textile colours resist being removed through dry and wet rubbing.

Scope and method:

• Applies to all textile types, including floor coverings and pile fabrics
• Assesses both dry and wet rubbing fastness, simulating real contact scenarios
• Involves the use of specific mechanical devices, standardized rubbing cloths, and grey scale evaluation for staining

Key requirements:

• Two-component test: one for dry, one for wet conditions
• Standardized pressure, movement, and test apparatus
• Grey scale assessment for grading transfer or staining

Who needs this test?

• Clothing, upholstery, carpet, and accessories manufacturers
• Automotive and interior fabric suppliers
• Quality and product development teams concerned with wear, touch, or color migration

Implementing this standard reduces the risk of customer frustration or negative brand exposure due to avoidable colour transfer.

Key highlights:

• Applicable to all textile types, including complex piles
• Tests simulate both dry and wet use situations
• Offers clear grading to support product claims and specifications
