This Japanese Industrial Standard specifies the bend test method for determining the bendability at room temperature for the symbol of MPlB among the magnesium alloy sheets and plates (hereafter referred to as "sheet") and the magnesium alloy strips and coiled sheets (hereafter referred to as "strip") specified in JIS H 4201 having the thickness of 0.5 mm to 1.0 mm.

1.1 This specification covers magnesium alloys in sheet and plate form designated as shown in Table 1.TABLE 1 Chemical Composition LimitsANote 1???Analysis shall regularly be made only for the elements specifically mentioned in this table. If, however, the presence of other elements is suspected or indicated in amounts greater than the specified limits, further analysis shall be made to determine that these elements are not present in excess of the specified limits.Note 2???The following applies to all specified limits in this table: For purposes of acceptance and rejection, an observed value or a calculated value obtained from analysis should be rounded to the nearest unit in the last right-hand place of figures used in expressing the specified limit.

This International Standard specifies the chemical composition of cast unalloyed magnesium. It specifies classification, designation, testing rules, marking, packing, transportation, storage, and information contained in the contract. This International Standard is for cast unalloyed magnesium produced by the silicon-thermo process or molten salt electrolysis process.

This International Standard specifies wet analytical methods for lead and cadmium. There are two methods for the simultaneous determination of lead and cadmium in magnesium and its alloys. Method A uses a matrixmatching technique for unalloyed magnesium and its alloys by inductively coupled plasma/atomic emission spectrometry (ICP/AES) or flame atomic absorption spectrometry (FAAS). Method B uses an extraction method for magnesium alloys with pretreatment procedures. Generally, Method A is recommended; also, Method B is designated where the matrix-matching method cannot be adopted due to complicated preparation of the assay standard solutions or where the combination of solvent extraction and FAAS is useful for analysts. These methods are applicable to the determination of lead and cadmium in the ranges of mass fractions of 0,0005 % to 0,04 % and 0,0005 % to 0,07 %, respectively.
