The gradescovered by this European Standard will experience maximumse rvice life in applications where the surface of the casting is subject to impact.This European Standard retains the s
15、a me format for clauses as EN 1559-1 and EN1559-2. It shall be used inconjunctionwith these standards. Where no text is given under a clause heading, the corresponding clauseof EN 1559-1 or EN 1559-2 applies. The structure of this standard is as follows:a) clauses and subclauses preceded by indicate
16、s no additional conditions to Part 1 or Part21)of EN 1559;b) subclauses without any marking are mandatory.2 NormativereferencesThe following referenced documents are indispensable for the application of this document. For datedreferences, only the edition cited applies. For undated references, the l

23、shall be carried out in accordance with EN ISO 7438. The type and location of bend test pieces shall be agreed between the manufacturer and purchaser. The test specimen shall withstand bending at roomtemperature (23 5) C through an angle of 150 without breaking into two or more pieces. Surface crack
