ASTM D3359-02 & 3M tape test

The ASTM D3359-02 standard was developed to test the coating resistance: it must adhere to the product based on its expected service life. There are two methods to test the coating adhesion:

  • Method A: is the Adhesive test, known as 3M tape test, is performed in-site, at the factory by the QC.
  • Method B: it is usually performed in a laboratory.

Remark: this standard is answering to product finishing quality concerns. For safety concerns other tests, mainly laboratory tests, are required.
