Dust Test Iso 8502-3 -

Why it matters: Dust can reduce coating adhesion, cause osmotic blistering, and create an early path for corrosion.

For asset owners and specifiers, the inclusion of ISO 8502-3 in project specifications—with clearly defined acceptance limits—is essential for ensuring that the significant investment in abrasive blasting yields a substrate truly ready for coating application. By quantifying dust, the industry moves closer to the goal of zero defects and extended asset lifecycles. dust test iso 8502-3
