NOTE 1) - For thicknesses of 0.5 mm < and ≤ 0.7 mm, the minimum elongation at break value may be decreased by 2 units. For thicknesses between 0.2 mm < and ≤ 0.5 mm, the minimum elongation at break value may be decreased by 4 units. For e ≤ 0.2 mm, the minimum elongation at break value may be decreased by 6 units.
NOTE 2) - For thicknesses below 1.5 mm, a maximum yield strength value of 235 N/mm² is permitted.
NOTE 3) - The values specified on the table are only applicable to surfaces with MA appearances. For surfaces with MB and MC appearances, the yield strength and tensile strength values increase by 20 N/mm² and the elongation at break values decrease by 2 units. Additionally, the HV value increases by 5 units.

EN 10139:1997

The surface finish can be "rough", "matt", "normal" or "bright". 
Products with MA and MB surface appearances are generally supplied with a "normal" surface finish (RL). If a "rough" (RR) or "matt" (RM) surface finish is requested, the respective symbol must be indicated in the description. 
The MC surface appearance must be supplied with a "bright" surface finish (RN). 
For delivery conditions C290 to C690, the possible impact on the product's mechanical properties of stress relaxation or recrystallization due to the action of high temperatures must be taken into account. 
Surface appearance Special Surface Finish Suitability for chrome plating and other coatings
Symbol Properties Field of application
MA Bright surface, metallically clean. Pores, small defects and scratches are allowed. All thicknesses and all heat treatments. RR, RM, RL -
MB Bright surface, metallically clean. Pores, small defects and scratches are allowed, provided that no change to the smooth and even appearance is visible to the naked eye. Thicknesses ≤ 2.0 mm. RM, RL Medium / High
MC Bright surface, metallically clean. Pores, small defects and scratches are allowed, provided that they do not affect the bright appearance of the surface. Thicknesses ≤ 1.0 mm. RN High

 

The different surface finishes are characterised by the following average roughness (Ra) reference values: 
Finish Roughness
Rough RR Ra ≥ 1.5 μm
Matt RM 0.6 μm > Ra ≤ 1.8 μm
Normal RL Ra ≤ 0.6 μm
Bright RN Ra ≤ 0.2μm.

 

EN 10268:2006

Surface appearance: The products covered by this European standard can only be supplied with surface appearance A, as defined in European Standard EN 10130. - some defects are allowed such as pores, light scratches, small marks or slight discolouration when they do not affect the formability or adhesion of surface coatings.
Surface finish: The surface finish of products covered by this European standard must meet the requirements of European Standard EN 10130 for products with a rolling width  600 mm, and the requirements of the EN 10139 European Standard for products with a rolling width < 600 mm.
