Introduction SDC Grey Scale for Staining
The SDC Grey Scale for Staining and Change in Colour gives textile labs a reliable way to grade colour fastness. Technicians place a tested fabric sample next to the scale and compare the contrast to assign a numeric grade. This method removes guesswork from visual assessment and keeps results consistent across different labs and operators. The scale set covers two separate tools: one grades colour change on the original fabric, and the other grades staining on an adjacent white fabric. Buying houses, garment factories, and independent testing labs across Bangladesh rely on this scale daily to confirm fastness ratings before shipment.

Frequently Asked Questions (FAQ) SDC Grey Scale for Staining
Q1: What does the SDC Grey Scale for Staining and Change in Colour measure?
It measures how much a fabric’s colour fades or transfers after a fastness test, such as washing, rubbing, or light exposure.
Q2: What is the difference between the two scales in this set?
The Change in Colour scale grades fading on the original tested sample. The Staining scale grades colour transfer onto an adjacent white fabric.
Q3: Which standards does this grey scale follow?
The set follows ISO 105-A02, SDC 105-A03, AATCC EP1, and AATCC EP2.
Q4: Do I need a viewing cabinet to use this scale?
A viewing cabinet with D65 daylight improves accuracy, but you can also use standard daylight conditions if a cabinet is unavailable.
Q5: How long does a grey scale set last?
With careful handling and storage away from direct sunlight and moisture, the chips retain their rating accuracy for years.
