Surface preparation required for paint application, shall be such as to clean the surface thoroughly of any material which will be conducive to premature failure of the paint substrates.
All surfaces shall be cleaned of loose substances, and foreign materials, such as dirt, rust, scale, oil, grease, welding flux, etc. in order that the prime coat is rigidly anchored to the virgin metal surface. The surface preparation shall confirm to pictorial representation of surface quality g r a d e o f S we d i s h S t a n d a r d s I n s t i t u t i o n SIS – 055900 or equivalent standards such as SSPC – VIS – 1.67 or DIN 55928(Part 4) or BS 4232 or IS 1477 – 1971 (Part I) The acceptable surface preparation quality / grade are described under e a c h p a i n t s ys t e m .

This method will remove loosely adherent materials but would not affect residues of rust or mill scales that are firmly adherent and intact. Blast Cleaning The surface shall be cleaned by impingement of abrasive materials, such as graded sand at high velocity created by clean and dr y compressed air blast as per the grade according to Swedish Standard Institution SIS 0 5 5 9 0 0 . T h i s m e t h o d wi l l r e m o v e l o o s e l y a d h e r e n t m a t e r i a l s a s w e l l a s adherent scales and mill scales. Prior to application of blast, heavy deposit of oil and grease are removed by solvent cleaning excessive
surface scales are removed by hand tools or power tool cleaning. The extent of removal of adherent scales is varied, depending on the application and are defined by the surface quality grades Sa1, Sa2, Sa2.5 and Sa3 in the order of increasing cleanliness. The blast cleaning is not recommended for sheet metal work.

(*) Supercritical :
Bearings whose failure can result in stoppage of either upstream or downstream process or require more than 8 hrs. for restoration of the equipment and the process of the department is stopped during this period or can result in huge consequential losses are classified as supercritical bearings. Based on this, 206 sizes are classified as supercritical bearings.
Critical :
Bearings whose failure can result into a stoppage of the process of the shop for less than 8 hours but more than 2 hours or affects downstream or upstream units to some extent are classified as critical bearings. Based on this, 595 sizes are classified as Critical bearings.
General :
Bearings whose failure can result in stoppage of process for less than 2 hours and sometimes no process stoppage is required immediately and standby or alternative arrangements can be made to maintain process continuity are classified as General purpose bearings. Based on this, 1882 sizes are classified as general purpose bearings.
Non standard Russian origin:
Bearings of supercritical / critical / general nature application supplied alongwith OEMs of Russian, CIS, or former East Block countries, whose substitutes are not available from other manufacturers are grouped under this category. 231 sizes are classified in this category.
Uncommon, Non-standard bearings of other origins:
The varieties of bearings whose consumption pattern is so low that no other manufacturer is ready to develop alternatives are classified as uncommon, non-standard of other origin. 127 sizes are classified in this category.
Sleeves :
Sleeves are to be procured from bearing manufacturers only for their bearings or from sources recommended by bearing manufacturers so that performance of bearing is guaranteed.
