for bs en iso 105 x18:2007 textiles - assessment of the potential to phenolic yellowing of materials.
based on a method developed around 1985 by courtauld's researchthis test can be used to screen fabrics for their susceptibility to exhibit phenolic, or elusive, yellowing – where garments or fabrics exhibit yellowing making them unfit for sale withoutre-processing.
through extensive sampling and testing procedures, sdce products not only are guaranteed to conform to the standard, they also have excellent continuity ofperformance from batch to batch over many years. testing not only includes practical and independent performance testing but also quantitative analysis of the concentration of active ingredient onthe papers.
due to the limited shelf-life of the papers, 3 months once the heat sealed barrier foil bags have been opened, sdce pack all their papers in small pack sizes toreduce waste or the temptation to use up out-of-date papers. also sdce have developed a woven tape for the control fabric, this relatively heavy construction makes assessment and grading of theyellowing easier for the technician.
