The practice presented in this scientific operating procedure (SOP) is intended to measure weathering effects on the retention of nanomaterial properties. This scientific standard operating procedure (SOP), SOP-R-1, is a weathering test for nanomaterials and describes how to perform a weathering test to rate the damage in nanocomposites and other technologies where nanomaterials have been incorporated. The SOP allows the user flexibility when determining which weathering cycle to apply to the nanomaterial but always references the proper way to make changes according to existing standards.
