Test method to measure the efficiency of air filtration media against spherical nanomaterials - Size range from 3 nm to 30 nmWhat is ISO TS 21083 2 Air filtration media about? ISO TS 21083 discusses a test method to measure the efficiency of air filtration media against spherical nanomaterials. ISO TS 21083 2 is the second part of the ISO TS 21083 multi series and discusses the size range from 3 nm to 30 nm. ISO TS 21083 2 specifies the testing instruments and procedure for determining the filtration efficiencies of flat sheet filter media against airborne nanoparticles in

For these applications

This part of IEC 61988 determines the following measuring methods for characterizing the performance of PDP modules (plasma display modules):

shear modulus and Poisson’s ratio

“Instructions for use” is a synonym for “information for use”

The cables covered in BS EN 50441-2 are intended to operate with voltages and currents normally encountered in communication systems

1) windscreen defrosting and demisting systems
