This isn't a job for untrained technicians. Artifacts like pullouts (where particles are physically pulled out during polishing) or smearing (where material is smeared across the surface) can easily be mistaken for porosity if the operator isn't experienced. What do you have available

When looking for the , it is crucial to understand copyright and compliance rules:

If you absolutely need the 2001 edition, buy it from ASTM International. The $60 investment ensures you have a legally admissible, error-free document. Never rely on free downloads—misplaced decimal points, missing pages, or incorrect neutralizer formulas can cause failed audits or product recalls.

Method B uses computerized image analysis equipment to automatically calculate the area percentage porosity. This approach offers greater precision, repeatability, and eliminates human subjectivity. It's particularly valuable when you need statistically robust data or when evaluating coatings for critical applications.
