18、ps which correspond to varying difficulty when manufacturing the products. Tighter thickness tolerances apply to Group I alloys (soft alloys). The grouping is carried out according to the specified chenucal composition limits of the alloys (see EN 573-3) as follows: - Group I alloys: - 1000 series a
19、lloys; - non heat-treatable 7000 and 8000 series alloys; - 4000 series alloys with less than 2 $6 maximum specified silicon content; - 3000 and 5000 series alloys for which the maximum specified magnesium and manganese contents are each no greater than 1,s % and their sum no greater than 2,3 %. - al
20、l alloys which do not belong to Group I. The split into Group I and Group II of the most commonly used general engineering alloys is given in annex A (see table Al). 3.1.2 Thickness tolerances for sheet, strip and plate are specified in table 1. 3.1.3 Other thickness tolerances may be agreed between
