Scope

GB/T 32792-2016 is the English-translated version of 镁合金加工产品包装、标志、运输、贮存.

China's national standard for the packing, marking, transport and storage of wrought magnesium alloy products. It applies to magnesium alloy castings, forgings, plates, strips, tubes, bars, profiles, wire and powder, and it specifies the general rules for packing, the packing methods for each product form, the marking, the transport and the storage. Magnesium is the reason this standard is separate from the equivalent one for aluminium. It is the lightest structural metal in use, which is why it is wanted, and it is also the most chemically active: a magnesium surface corrodes readily in the presence of moisture, and magnesium in finely divided form - chips, powder, swarf - burns and cannot be extinguished with water. Packing a magnesium product is therefore not only a matter of preventing mechanical damage in transit but of keeping moisture away from a reactive surface for however long the product sits in a warehouse, and packing magnesium powder is a dangerous goods problem, which is why GB 190 for dangerous goods package labels appears among the normative references alongside the ordinary handling marks of GB/T 191. The standard sets out the packing method by product form, since a coil of strip, a bundle of extruded profile and a drum of powder present entirely different problems, and it prescribes the marking that must travel with each package. Transport and storage close the document, covering the conditions under which the products may be moved and held. Issued on 29 August 2016 and in force since 1 July 2017.
