NACE No. 2/SSPC-SP 10 – 2024

This standard defines the process for preparing a carbon steel surface to the Near-White Metal degree of surface cleanliness using a dry abrasive blast method of cleaning. This standard is intended for use by coating or lining specifiers, applicators, inspectors, or others whose responsibility is to specify, prepare, or inspect carbon steel surfaces to the degree of surface cleanliness required by this standard. The requirements include the end condition of the surface as determined by visual inspection and the materials and procedures used to achieve and verify the end condition. Appendix A (nonmandatory) provides additional supplementary information. Paragraph A1 provides an example of language that may be used in a project specification where SSPC-SP 10/NACE No. 2 is specified.

This standard is limited to requirements for visible surface contaminants. Information on nonvisible surface contaminants (NVSC) and an example specification statement are in Paragraph A2. Information on soluble salt testing is in SSPC-Guide 15.

SSPC-SP 10 (WAB)/NACE WAB-2 should be specified if wet abrasive blast cleaning (WAB) technology is required.
