A colourfastness result is tied to an exposure and method. When the concern involves a different contact condition, another result may be needed.
Intertek includes perspiration among the exposure conditions considered in colourfastness testing. Colorfastness Testing.
Describe the concern
For a handled textile product, explain the intended use and relevant contact question to the testing specialist. Do not select a method only because a report for another exposure is already available.
Read the evidence narrowly
Identify the specimen, method and applicable acceptance criteria. No universal passing grade or product-life promise is proposed here. The value of the report depends on whether it addresses the actual material and question under review.
