Read on Graco why two dominant surface preparation standards through abrasive blasting, ISO 8501 and the SSPC/NACE joint standards, are tough to compare.
ISO 8501-1 is a pictorial standard relating to surface cleanliness, amongst other methods, though abrasive blasting. The original condition of steel surfaces prior to blasting are depicted in various stages of corrosion as follows: Grade A.
5 Ιουν 2021 · I need to know the technical details about the following- Surface preparation - Cast Iron part (gratings, used for cooking ranges); the surface needs to be prepared by sand blasting as per Swedish Standard, SA 2.5 or better as per Swedish Standard, SA 3.
This standard refers to surfaces of hot-rolled steel in four different rust grades (A, B, C and D) the same surfaces prepared to two grades of surface quality (St 2 and St 3) by manual scraping and wire-brushing - machine brushing - grinding-etc.
1) The document discusses various surface preparation standards including Swedish SA 1, SA 2, SA 2.5, SA 3 and NACE. 2) It provides descriptions of each standard level, from SA 1/Brush Off being the lowest level of cleanliness to SA 3/White Metal being the highest level.
The standard grades of cleanliness for abrasive blast cleaning in accordance with BS EN ISO 8501-1 are: Sa 1 – Light blast cleaning; Sa 2 – Thorough blast cleaning; Sa 2½ – Very thorough blast cleaning; Sa 3 – Blast cleaning to visually clean steel; Specifications for bridge steelwork usually require either Sa 2½ or Sa 3 grades.
