More information about the evaluation criteria for color transfer in these standards?

Certainly! The evaluation criteria for color transfer in rubbing fastness testing can vary depending on the testing standard used. However, the general approach involves visually assessing the extent of color transfer or staining on the rubbing finger and/or the fabric being tested. Here are some common evaluation criteria used in the mentioned standards:

1. ISO 105-X12: The ISO 105-X12 standard provides a grading scale ranging from 1 to 5 to evaluate colorfastness to rubbing. The scale is as follows:

   - Grade 1: Severe color transfer.

   - Grade 2: Moderate color transfer.

   - Grade 3: Slight color transfer.

   - Grade 4: Negligible color transfer.

   - Grade 5: No color transfer.

1. AATCC Test Method 8: In this method, color transfer is evaluated visually and graded on a scale of 1 to 5. The scale is similar to the ISO standard:

   - Grade 1: Severe color transfer.

   - Grade 2: Moderate color transfer.

   - Grade 3: Slight color transfer.

   - Grade 4: Slight color transfer with no staining.

   - Grade 5: No color transfer.

1. ASTM D6037: The ASTM D6037 standard does not provide specific grading criteria for color transfer. Instead, it recommends comparing the tested fabric with a set of dyed fabric standards to determine the degree of color transfer.

1. GB/T 3920: The GB/T 3920 standard uses a grading scale from 1 to 5 to assess colorfastness to rubbing. The scale is similar to the ISO and AATCC standards.

It's important to note that the specific evaluation criteria may vary depending on the testing standard and the purpose of the evaluation. The grading scales mentioned above are general guidelines, and it is advisable to refer to the specific standard you are using for precise details on evaluation methods and criteria.
