4.2 This method is applicable to acceptance testing.

ASTM B487-2013 Standard Test Method for Measuring the Thickness of Metal and Oxide Coatings by Cross Section Microscopy

Etapa 1: Domeniul de aplicare

1.1 The test method includes the use of an optical microscope to measure the local thickness of the metal and oxide coating by examining the cross section under a microscope.

1.2 Under good conditions, the method can provide an absolute measurement accuracy of 0.8μm when using an optical microscope. This will determine the suitability of the method for measuring the thickness of the thin coating.

1.3 Acest standard nu este destinat să abordeze toate preocupările legate de siguranță, dacă există, asociat cu utilizarea acestuia. Este responsabilitatea utilizatorilor acestui standard de a stabili practici adecvate de securitate și sănătate și de a determina aplicabilitatea restricțiilor de reglementare înainte de utilizare..
