GB 2626-2019 Annex E has a summary of comparison between GB 2626-2019 and GB 2626-2006. Below are the highlights of the major differences.
Major differences include but not limited to:
1. Some test parameters and procedures are more specific, such as particle filtration efficiency tests, head strap tensile strength test, etc.
2. Inhalation pressure resistance and exhalation pressure resistance are with standardized limits regardless to the type of masks in 2006 version. The new version would have different requirements depending on the type of masks and filtration efficiency, because the higher the filtration efficiency, the more effort required to breathe through the mask (the differential pressure on inhalation and exhalation are larger) and with larger differential pressure tolerance.
