Description
Nanoparticle Size Standards (NIST, SRM, ASTM)
Nanoparticle Size Standards (NIST, SRM, ASTM)
Nanoparticle Size Standards are uniform polystyrene spheres calibrated in nanometers (nm) with NIST traceable methodology.
1 nanometer = 0.000000001meter
1 nm= 0.001 micrometer (µm, micron)
1 nm= 10 Angstrom units.
Test Sand & Test Dust
Test Sand & Test Dust
How hydraulic, automotive, and aerospace application components perform when exposed to particles of sand and dust is essential during use as well as lifetime durability and performance. Sand and dust test standards address environmental conditions that materials and products may face during operation so contamination by solid particles can be controlled. These standard reference materials have been designed to improve precision and accuracy in particle counting.
