Test item Test method Technical index Test result Evaluation
Anti-mold performance LY/T 2230-2013 Grade 0 (Strong Anti-mold Grade) The mold growth grade value is 0 The mold growth grade value is 0 Grade 0
Grade 1 (Anti-mold Grade) The mold growth grade value is 1
Remarks
  1. Detecting strains: Aspergillus niger, Aspergillus flavus, Penicillium citrinum, Trichoderma viride, Aureobasidium pullulans, Chaetomium globosum..
  2. The incubation time was 28 days.
  3. Mold growth grade: Grade 0 indicates no growth, meaning there is no mold growth on the surface and no mold growth is observed under a low-power (50x)biological optical microscope. Grade 1 indicates trace growth, that is, there is a little mycelium on the surface of the specimen, but the infected area is ≤10%.
