We are proudly to announce that SGS has been accredited by the IDFB (International Down and Feather Bureau) for feather and down testing under its jurisdiction. In 2006, the Federal Standard 148a, an older standard governing all testing of feather and down products in the States, was cancelled.

Therefore, an American Society and Testing and Materials standard, the ASTM D4522-2004 has taken over and becomes the only legitimate American standard regarding testing methods for feather and down samples to be imported to the States. As the ASTM D4522-2004 only provided the methodology for composition testing as ASTM D4524-2005, for other testing procedures, it is required to refer to the IDFB testing methods.
