| (ISO8501-1 | 2007) |
| Shop primers without type approval must be blast cleaned to Sa 2 (ISO 8501-1 | 2007); at least 70% of the intact shop primer must be removed |
| Welded areas, where the shop primer is rusted or damaged, shall be blast-cleaned to | Sa2.5 |
| (ISO8501-1 | 2007). In any part of the blast-cleaned area, the surface roughness should be in the range of 30~75 µm |
| (ISO8503-1/2 | 1988) |
