PPECO is a brand of Taylor Garfit Ltd an independent design consultancy, based in Preston, who developed an innovative face visor in response to the Coronavirus (COVID-19) pandemic. The face visor, which can be produced at low cost for supply into the UK market will be affordable to developing nations. The current design uses cardboard frame and cellulose optic rather than a conventional polymer-based frame and optic. The design allows the single use device to be disposed of in a more environmental way than current products as it is fully biodegradable and recyclable.
NPL’s M4R programme helped PPECO by reviewing the CAD model of the device to determine the area of coverage and field of view as well as reviewing of the visor against relevant testing standards to identify and mitigate any issues. NPL also loaned a test head to do some simple testing on the design.
The M4R programme also helped PPECO address the challenges around ensuring that the current design will be able to meet the reduced testing requirements under Covid-19 provisions.
