Table 2 gives guideline values, with any other rangesbeing subject to agreement.Table 2: Particle sizes for ferrochromium and ferrosilicochromium4.3 Form suppliedChromium, ferrochromium and ferrosilicochromium may be supplied in lumps up to 300 mm long (commerciallyreferred t

16、o as KG 0-300), or crushed and or screened, in which case the particle size is subject to agreement.The surface of the material shall be free from foreign matter, such as sand, slag, etc.The material shall be free from harmful matter and shall not emit any ionizing radiation (such radiation beingund

17、erstood to be radiation higher than the background radiation at the time of receipt by the customer).5 AnalysisThe 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 o

18、bserved.6 Rounding of resultsResults as calculated or observed are to be rounded following the rules set out 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

19、 the last significant place is less than five, then the latter shall remain unchanged;b) if the figure following 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

20、, labelling and packaging shall be at the suppliers discre-tion.Ferrosilicochromium, with or without packaging, shall be transported and stored so as to be protected againstmoisture, in accordance with any relevant regulations.G50G65G72G6DG69G73G73G69G62G6CG65 G75G6EG64G65G72G73G69G7AG65G2C G61G73 G
