BS EN ISO 105-Z01:1996 is a European standard that specifies a test method for assessing the resistance of colorants to migration into or onto polyolefin or paper materials. This standard is part of the ISO 105 series of tests, which cover various aspects of colorfastness and color measurement.
In this specific test method (ISO 105-Z01:1996), the migration of colorants is evaluated by placing a colored fabric or paper strip in contact with a polyolefin or paper material. The samples are subjected to elevated temperature and pressure conditions, simulating possible migration of colorants under practical usage scenarios. After the test, the degree of colorant migration is visually assessed based on staining or discoloration of the contacting material.
It's worth noting that standards can be updated or revised over time to reflect advancements in technology and testing methodologies. Therefore, if you're looking for the most up-to-date information or if there have been any changes to this standard since 1996, you should consult the official standards organization or relevant sources.
