The Egyptian Organization for Standardization and Quality (EOS) has announced the full requirements for the production of fabric facemasks on its website. These cloth face masks are not intended for use in hospitals among medical teams and patients. These masks will be subject to six tests at the EOS’s headquarters to determine its efficiency after 25 washes, ensuring that particles of a size over three microns cannot pass. Another test will be related to its resistance to water penetration and wetness according to the ISO 811 and ISO 4920 testing methods. And lastly, a stability test on the masks will check their strength after changes in dimension and being washed at a minimum of 25 times.
