Swedish standard SIS 055900 contains two pictorial standards for manual cleaning, St2 and St3. Both require the removal of loose millscale, surface rust and foreign matter. The second and higher standard describes the prepared and dusted surface as having a pronounced metallic sheen. The St2 preparation is described as a faint metallic sheen . Both are expected to correspond with their respective coloured prints in the standard. These relate to four grades of new unpainted steel ... 

There are three standards controlling surface finish in common use. They are issued by the Steel Structures Painting Council (USA), the Swedish Standards Organisation and the British Standards Institution. They are roughly equivalent.

In BS 4232, Surface Finish of Blast Cleaned Steel for Painting, first quality corresponds to SA3,2nd to SA2-5 and 3rd toSA2of the much more extensive Swedish Standards Commission s SIS 055 900-1962, RusI Grades for Steel Surfaces and Preparation Grades Prior to Protective Coaling, Stockholm (1962) see also BS 7079 Part A1 (1989)... 

All metal surfaces such as mild steel should be grit blasted, normally to SA 2-5 as defined in Swedish Standard SIS 055900. If the surfaces are contaminated with oil, grease or a chemical from previously used items, the contamination is usually removed by sweating in steam prior to grit blasting. Concrete surfaces must be clean and dry and any laitence must be removed as it will affect the bond of the lining. Preferably the surface should be grit blasted. 

Test samples have been prepared from a 3 mm hot-rolled steel sheet which showed an intact mill scale (Degree A of Swedish Standards, SIS-055900), Thereafter they were shot blasted with S-280 to reach the ASa3 standard, prior to the application of the paint coating. Surface preparation B St 2 was obtained by wire brushing a steel sheet of Grade B obtained in turn by oxidation of Grade A sheet in a contaminant free atmosphere. In "Table I.", the characteristics of the paints used in this study are shown. 

A near white surface finish corresponds to Swedish standard Sa 2-1/2 or BS4232 second quality. This finish is defined as one from which is removed all oil, grease, dirt, mill scale, rust, corrosion products, oxides remaining coatings, except for a very light shadows of light streak discolouration. At least 95% of the surface shall have the appearance of a white metal surface finish and the remainder shall be limited to light discolouration. 

A commercial blasted surface finish corresponds to Swedish Standard Sa2 third quality. The finish is defined as one from which oil, grease, dirt, rust-scale and foreign matter have been completely removed from the surface, except for slight shadows, streaks or... 

Swedish standard SIS 05 5900-1967. A degree of preparation equal to Sa 2 is usually employed for most industrial painting projects.

Carbon-molybdenum steel also presents problems. BS.3604 does not include the alloy at aU. French, German and Swedish standards do have this type of steel, but the minimum molybdenum steel is used as a hydrogen resistant material. This... 

Hundreds of thousands of freight containers have been built worldwide since the early 1960s. They are exposed to many types of climate and are heavily stressed by wear and tear. Freight containers consist of steel or aluminum alloy frames, clad with sidewalls and roofs made of steel, stainless steel, or aluminum alloys. The walls and roofs may be coil-coated. Container frames are usually blasted to grade 2 Vi of the Swedish Standard SIS 055900.

In order to obtain a good result with thermal spraying it is quite necessary that the base material is clean, dry and rough all over prior to spraying. Therefore blast cleaning to a grade of Sa3 after the Swedish standard SS 055900 (ISO 8501-1) is specified (see also Section 10.6.4). 

The cost of the paint itself forms often 15-20% of the total cost of the painting operations including pre-treatment and application. It is important that the pretreatment and the type of paint are compatible. The advanced paints depend upon good pre-treatment (as indicated in Table 10.19) to obtain the necessary adhesion to the substrate. In Table 10.19, the pre-treatment quality is denoted with cleanliness grades which are defined in a Swedish standard, and in recent years included in the... 

If necessary remove heavy layers of rust by hand or mechanical abrasion with emery cloth or by wire brushing to give rust grades A or B as defined in Swedish Standard SIS 055900 (20). 

Grit blast to grade 2k of Swedish Standard SIS 055900 (20) to achieve a maximum peak-to-valley depth of at least 50 p.m, using a hard angular clean metal grit which is free of any grease contamination. 

Surface preparation. The surface of the rebar is blasted to a surface cleanliness at least as good as Swedish Standard ASa 2.5. A surface texture of around 70 jxm depth is aimed for. This is typical of steel surface preparation requirements for other structural bonding applications (see Chapter 6).

Table 1 provides the basic data used to describe the materials, ropes, and machine characteristics in the model. The values in Table 1 are based on existing steel ropes and an equivalent synthetic rope as well as the existing hoists at LKAB. Future bend-over-sheave testing of ropes will determine whether or not an increased diameter is feasible. Maximum friction coefficient used in all cases is the maximum value allowed by the Swedish standards for mining hoists (BRAGS). While the friction values can be considered high, it is assumed that apphcation specific drum hning materials can be developed to be used with synthetic ropes.
