After consultation with stakeholders in both countries,
10、Standard Australia and Standards New Zealand decided to develop this Standard as an Australian, rather than an Australian/New Zealand Standard. This Standard is identical with, and has been reproduced from ISO 17804:2005, Ausferritic spheroidal graphite cast ironsClassification. The objective of thi
11、s Standard is to specify five grades of Ausferritic spheroidal graphite cast irons which have been classified by mechanical properties. This Standard is one of a series of Standards covering the range of tensile testing methods. The series comprises the following: AS 1830 Grey cast iron 1831 Ductile
