THE SWEDISH STANDARDS INSTITUTION:
Surface Preparations Standards for Painting Steel Surface (SIS 055900 - 1967) has gained prominence and acceptance and has served as a model for and has even been adopted direct as national standard in other countries. its cleaning degrees Sa 2, Sa 2.5 etc... being pracically universally recognized, they are reffered to throughout this book in recommendations for cleaning of steel. The Swedish Standard, as it was usually called, was first to employ pictorial representations for the specified cleaning degrees.

Other prominent standards, notably

• STEEL STRUCTURES PAINTING COUNCIL (U.S.A.):
• Surface Preparation Specifications (SSPC-SP 2,3,5,6,7 and 10)
• BRITISH STANDARDS INSTITUTION: Surface Finish of Blst-Cleaned Steel for Painting: (BS 4232 but now superseded by BS 7079) and

DIN 55928, Protection of steel structures form corrosion by organic and metallic coatings; preparation and testing of surfaces (Germany)
Sa 3:- Blast-cleaning to visually clean steel.
When viewed without magnification, the surface shall be free from visible oil, grease and dirt, and shall be free from mill scale, rust, paint coatiings and foreign matter. it shall have uniform metallic colour.
Sa 2.5:- Very thorough blast-cleaning.
When viewed witout magnification, the surface shall be free from visible oil, grease and dirt, and from mill scale, rust, paint coatings and foreign matter. Any remaining traces of contamination shall show only as slight stains in the form of spots or stripes.
Sa 2:- Thorough blast-cleaning.
When viewed without magnigication, the surface shall be free from visible oil, grease and dirt, and from most of the mill scale, rust, paint coatings and foreign matter, Any residual contamination shall be firmly adhering (see note 2 below).
Sa 1: Light blast-cleaning.
When viewed without magnification, the surface shall be free from visible oil, grease and dirt, and from poorly adhering mill scale, rust, paint coatings and foreign matter (see note 2)

Notes:
The term "foreign matter" may include water-soluble salts and welding residues.

• These contaminants cannot always be completely removed from the surface by dry blast-cleaning, hand and power tool cleaning or flame cleaning; wet blast-cleaning or hydro-jetting may be necessary.

Mill scale, rust or a paint coating is considered to be poorly adhering if it can be removed by lifting with a blunt putty knife.

• St 3 very thorough hand and power tool cleaning.
• As for St 2, but the surface shall be treated much more thoroughly to give a metallic sheen arising from the metallic substrate. See photographs B St 3, C St 3 and D St 3. St 2 Thorough hand and power tool cleaning.
• When viewed without magnification, the surfaces shall be free from visible oil, grease and dirt, and from poorly adhering mill scale, rust, paint coatings and foreign matter (see note 2).
