On 11th April 2020, two units of the Ordnance Factory Board (OFB), namely the Small Arms Factory (SAF) Kanpur in U.P. and the Heavy Vehicles Factory (HVF) Avadi in Tamil Nadu, were granted accreditation by the NABL for conducting the “Test for Blood Penetration Resistance” as the Test Equipment manufactured by them met the ASTM F 1670:2003 and ISO 16603:2004 standards.
The basic principle of the test is to expose the fabric, used as a raw material to manufacture coveralls, to ‘synthetic blood’ at different pressure levels for specified periods of time.
The test is essentially required to facilitate bulk manufacture of coveralls by manufacturers all over the country for health workers and first responders dealing with patients afflicted with the corona virus. Testing of the fabric for manufacture of coveralls has emerged as a critical bottleneck specially during the nationwide lock down and in the absence of logistics.
