15、ysisThe method of analysis shall be at the manufacturers discretion, a state-of-the-art procedure being used incases of dispute.When rounding results, the specifications of clause 6 are to be observed.6 Rounding of resultsResults as calculated or observed are to be rounded following the rules set ou
16、t in Annex B of ISO 31-0. The valueis to be rounded in one step to the same number of places as are specified in this standard.The results shall be rounded as follows:a) if the figure following the last significant place is less than five, then the latter shall remain unchanged;b) if the figure foll
17、owing the last significant place is five or higher, the latter shall be increased by one.7 Marking, labelling, packaging, transport and storageUnless otherwise requested or agreed upon, marking, labelling and packaging shall be at the suppliers discre-tion.Silicon should be transported and stored so
