30、r, unless otherwise agreed between the purchaser and the supplier. 6.3 Surface condition The surface condition of the ingots and jumbos shall be such that it does not affect the composition and is not detrimental to the use of the ingots. 7 Sampling and analysis 7.1 Sampling Sampling shall be carrie
31、d out in accordance with EN 12402. 7.2 Analysis When analysis is carried out by the supplier to verify conformity of a cast, the analytical methods used shall be at his discretion. NOTE When optical emission spectrometry is used, the method should conform to ENV 12908. In case of dispute concerning
32、the results of analysis, the relevant methods of analysis of the prENVs in preparation (see bibliography) to be used to control the compositional conformity of a consignment, apply. NOTE Due to the nature of samples prepared, only chemical analyses are feasible. 7.3 Rounding of the results of analys
33、is The values obtained shall be rounded to the same number of decimal places as used to express the specified limit in table 1.
