1 Introduction
1.1 The steel plate, used for certain crucial welding assembly, such as shipbuilding, offshore production platform, boiler and pressure vessel, not only require certain mechanical property of its broad ways and length heading ,but also satisfactory lamellar tearing- resistant performance of its thickness. The steel plate’ performance in the lamellar tearing resistance aspect can be assessed by reduction in area when doing tension test of through-thickness.
1.2 This standard is applicable to killed steel plate with thickness between 15mm and 150mm, and with yield point no larger than 51 kgf/mm2 (500n/mm2). For the steel plate which the thickness is less than 15mm or greater than 150mm, or the yield point is greater than 51kgf/mm2 (500N/mm2), specific requirements shall be negotiated at order time.
1.3 The standard serves as supplementary provision for relevant standard steel plate requiring through-thickness property test.
