Sdc Fading Grey Scale - China

Applicable Standards

The SDC Grey Scale adheres to international colorfastness testing protocols, including: ISO 105-A02 (Grey Scale for Assessing Change in Color)

AATCC Evaluation Procedure 1 (Grey Scale for Stain and Color Change)

BS EN ISO 105-A02 (British/European equivalent)

JIS L 0801 (Japanese Industrial Standard for Grey Scale Assessment)

These standards ensure uniformity in color change evaluation, facilitating global trade and compliance.

Working Principle

The Grey Scale operates as a visual reference tool: Color Comparison: Users place the test specimen alongside the Grey Scale chips under standardized lighting (e.g., D65 illuminant).

Rating Assignment: The degree of color change is matched to the closest Grey Scale pair, with 1 = severe fading and 5 = no visible change.

Objective Grading: Half-step increments (e.g., 4-5) allow nuanced evaluation for borderline cases.

Test Principle & Applications

The Grey Scale is used in controlled testing environments to: Lightfastness Testing: Assess dye durability after xenon arc or weatherometer exposure (e.g., ISO 105-B02).

Wash Fastness: Evaluate color bleeding or staining after laundering (AATCC 61, ISO 105-C06).

Perspiration/Rub Fastness: Measure color retention under simulated wear (ISO 105-E04, AATCC 8).

Key Applications: Textile Manufacturing: Quality control for dyes and finishes.

Retail: Verifying color consistency in garment production.

Research: Developing fade-resistant pigments for automotive/aerospace textiles.

The SDC Fading Grey Scale is an indispensable tool for industries requiring precise colorfastness evaluation, offering a standardized, cost-effective solution to ensure product performance and customer satisfaction.
