Grey Scales

Grey Scales in Bangladesh

Grey Scales (or Gray Scales) provide a standardized visual assessment to rate colorfastness on a scale of 1 to 5. Whether you are following ISO, SDC, or AATCC standards, these scales are the bridge between your production and buyer approval.

The Two Essential Types of Grey Scales

To provide a complete quality report, two specific scales are required:

1. Grey Scale for Color Change (ISO 105-A02 / AATCC EP1)

Used to evaluate the contrast between a treated textile sample (after washing, rubbing, or light exposure) and the original untreated fabric.

  • Grading: Ranges from Grade 5 (No change) to Grade 1 (Severe change).

  • Application: Essential for wash fastness, light fastness, and perspiration tests.

2. Grey Scale for Staining (ISO 105-A03 / AATCC EP2)

Used to measure how much color has transferred from your dyed specimen onto an undyed adjacent fabric (multifibre) during testing.

  • Grading: Ranges from Grade 5 (No staining) to Grade 1 (Heavy staining).

  • Application: Critical for ensuring that multi-colored garments do not “bleed” onto white panels during use.

Technical Specifications & Features

  • Brand Options: SDC (UK), James Heal (UK), or AATCC (USA).

  • Certification: Each scale comes with a Certificate of Conformity to meet audit requirements (M&S, NEXT, H&M, Walmart).

  • Durability: Non-glossy, neutral grey chips mounted on high-quality backing.

  • Included Accessory: Most sets include an Assessment Mask to isolate the sample and prevent visual interference.

Best Practices for Visual Assessment

To ensure the most accurate results in your BD lab:

  1. Standard Lighting: Always use a light box with a D65 Artificial Daylight source.

  2. Viewing Angle: Place the scale and sample at a 45-degree angle.

  3. Replacement: Professional scales should be replaced every 12–24 months as the grey chips can fade or become soiled over time, leading to inaccurate readings.
