The filter area material used for transparent face masks shall not exceed the differential pressure requirements for Type IIR masks in section 5.2.3 in BS EN 14683:2019. 5.8 Splash resistance Type II face masks (EN14683) are medical face masks made up of a protective 3 ply construction that prevents large particles from reaching the patient or working surfaces, however they are not effective when blood or bodily fluids are present. The wearing of a mask for protection against droplet or splash to the wearer when in close proximity an infected individual (for example, within 2 metres for COVID-19 or influenza).

Class N: no oil resistance. A distinction is made between N95, N99 and N100. The number after the letter indicates the percentage of filtration of suspended particles. if a mask consists of 2 or more areas with different characteristics or different layer-composition, each area can be tested individually Andy Burnham, Mayor of Greater Manchester, said: “This is real positive news for Greater Manchester, and is a result of the hard work of our PPE taskforce and their efforts to respond to the huge health and logistical challenges posed by the pandemic.An area of the mask, usually consisting of a transparent plastic area, panel or moulding, which aids the visibility of the wearer’s lips, mouth and the majority of their face.

The aim of the group was to produce a technical specification, based on test methods and some of the design and performance requirements used in established/recognised standards, for transparent face masks, some of which could be considered for use as an alternative to Type IIR medical masks.

The argument that’s made for their use by The European Centre for Disease Prevention and Control among others is that they could help to limit transmission of the virus in busy public situations where social distancing is difficult, such as public transport or supermarkets. The group which authored this document recognise the difficulty of demonstrating that transparent masks comply with existing medical mask performance standards such as BS EN 14683:2019, and particularly in demonstrating that they perform comparably to a Type IIR medical mask, which is the usual choice of mask for source control and wearer protection to prevent infection spread over short distances via droplets. 6.2 Probable mechanism of action
