If the third and fourth largest amount of elements are above or equal to 1, the higher amount of elements is taken; if of equal percentage, the third letter is decided by the producer who developed the alloy.
The chemical composition of wrought magnesium alloys, taken as cast analysis at the time the material is cast, shall conform to the requirements for the appropriate material given in Table 2.The minimum values of the mechanical properties of wrought products in magnesium alloys in the defined temper conditions shall be as given in Tables 3 to 48.Conditions for sampling, formation of batches and frequency of verification shall be subject to an agreement between the manufacturer and the purchaser.Test pieces shall be taken in the longitudinal direction. For rolled flat products of thickness > 0,6 mm,test pieces may be taken in the long transverse direction.
The number representing the result for any value specified in this document shall be expressed to the same number of decimal places as the corresponding number in this document. The rounding of numbers shall meet the requirements of ISO 80000-1:2009, B.3, rule A or B.
