The news is in response to a petition the CPSC received on Feb. 4 from the International Association of Users of Artificial and Synthetic Filament Yarns and of Natural Silk requesting changes to the pre-test conditions for clothing textiles for flammability testing.
The standard requires samples to be treated in an oven at 221 degrees Fahrenheit and then placed in a desiccator to cool. The petition stated this process removes all moisture from silk fabric sample and results in unrealistic measures of textile flammability.
The proposal asked that the standard be changed to require that all clothing textile samples, including silk, be conditioned at a lower temperature and at a higher level of humidity.
In addition, the petition requests that the CPSC amend the standard to include a new subsection that applies to flammability testing of refurbished textiles.
