BS ISO 1409:2020 PDF

Scope: What is ISO 1409 about? ISO 1409 is an international standard used for plastics/rubber that specifies the test method which determines the surface tension of polymer dispersions and rubber latices. ISO 1409 specifies two methods for the determination of the surface tension of polymer dispersions and rubber latices (natural and synthetic). Method A is the ring method (Du Noüy ring method) Method B is the plate method (Wilhelmy plate method) Who is ISO 1409 for ? ISO 1409 on Plastics/rubber is useful for: Manufacturer of automobile Construction of the building Manufacturer of tubes Manufacturer of plastics Why should you use ISO 1409? Surface tension is responsible for the shape of liquid droplets. These droplets of water tend to be pulled into a spherical shape by the cohesive forces of the surface layer. ISO 1409 helps you in achieving dispersion or latex diluted with water to a mass fraction of total solids. The total solid contents are reduced which results in ensuring the viscosi...
