It should be used in conjunction with these documents. Where no text is given under a clause heading, the corresponding clause of
18、EN 1559-1:1997 or EN 1559-2:2000 applies. The structure of this standard is as follows: clauses and subclauses preceded by indicate no additional conditions to EN 1559-1:1997 or EN 1559-2:20001); subclauses and paragraphs marked with a single dot indicate that the conditions shall be agreed at the t
19、ime of enquiry and order; subclauses marked with two dots indicate that conditions may be agreed at the time of enquiry and order (optional); subclauses without dot marking are mandatory. 1) When additional information is given in a clause or subclause of this standard (versus the same clause or sub
20、clause of EN 1559-1:1997 or EN 1559-2:2000) it is preceded by: “In addition to EN 1559:“. BS EN 10283:2010EN 10283:2010 (E) 5 1 Scope This European Standard applies to corrosion resistant steel castings for general purposes. This standard relates to castings manufactured from martensitic, austenitic
21、, fully austenitic and ferritic-austenitic steel grades characterised by their chemical composition (see Table 1) and mechanical properties (see Table 2). In cases where castings are joined by welding by the founder, this European Standard applies. In cases where castings are welded: to wrought prod
22、ucts (plates, tubes, forgings); or by non founders; this European Standard does not apply. 2 Normative references The following referenced documents are indispensable for the application of this document.
