<br />Appendix A: Explanatory Notes
<br />(Nonmandatory)
<br />A1 FUNCTION: Near-white metal blast cleaning (SSPC-
<br />SP 10/NACE No. 2) provides a greater degree of cleaning
<br />than commercial blast cleaning (SSPC-SP 6/NACE No. 3)
<br />but less than white metal blast cleaning (SSPC-SP 5/NACE
<br />No. 1). It should be used when a high degree of blast cleaning
<br />is required. The primary functions of blast cleaning before
<br />coating are (a) to remove material from the surtace that can
<br />cause early failure of the coating and (b) to obtain a suitable
<br />surface profile (roughness) to enhance the adhesion of the
<br />new coating system. The hierarchy of blasting standards is
<br />as follows: white metal blast cleaning, near-white metal blast
<br />cleaning, commercial blast cleaning, industrial blast cleaning,
<br />and brush-off blast cleaning.
<br />A2 MAINTENANCE COATING WORK: When this stan-
<br />dard is used in maintenance coating work, specific instructions
<br />should be provided on the extent of surface to be blast cleaned
<br />or spot blast cleaned to this degree of cleanliness. In these
<br />cases, this degree of cleaning applies to the entire specified
<br />ASTM International (ASTM), 100 Barr Harbor Drive, West Coshohocken, PA 19428-2959.
