I saw the HIFA post Coronavirus (371) Very simple face shield using plastic sheet + tape, with your note.
I came across this WHO document the other day - not sure if it's the latest version.
For face shields it states:
'Made of clear plastic and providing good visibility to both the wearer and the patient. Adjustable band to attach firmly around the head and fit snuggly against the forehead, fog resistant (preferable). Completely cover the sides and length of the face. May be re-usable (made of robust material which can be cleaned and disinfected) or disposable
• EU PPE Regulation 2016/425
• EN 166
• ANSI/ISEA Z87.1 or equivalent'

I also came across this some time ago http://www.factechnology.com/category/covid-19/?fbclid=IwAR1ZkxBZBSypo3B... but have been unable to verify if this meets recommended guidelines.
