GB/T 28618-2012Remanufacturing - General technical requirements for mechanical products (English PDF)

1 Scope

China's national general technical requirements for the remanufacturing of mechanical products. It specifies the general rules and the general technical requirements for remanufacturing, applies to the remanufacturing of mechanical products, and may be used as a reference for the remanufacturing of other products. Remanufacturing is not repair and it is not recycling, and the standard's value begins with holding that line. Repair restores a product to working order; recycling destroys the product to recover its material. Remanufacturing dismantles a used product to its components, restores those components to as-new condition by industrial process, and reassembles them into a product that meets the performance and the warranty of a new one. The used product is the raw material, and the output is a product sold as a product. The economics are what make it worth standardising. A remanufactured engine, gearbox, pump or hydraulic cylinder embodies the energy and material already invested in the original casting and machining, so it costs a fraction of a new one in both money and carbon while performing identically. China has a very large installed base of machinery and a policy interest in exactly that arithmetic. What stands in the way is trust: a buyer has to believe that a remanufactured unit is not a cleaned-up used one. So the general rules require compliance with the resource and environmental legislation, and the technical requirements cover the whole route - the acceptance and assessment of the used core, the dismantling and cleaning, the inspection and classification of components, the restoration processes, the reassembly, the testing of the finished product against the requirements for a new one, and the marking that identifies it as remanufactured. Issued on 29 June 2012 and in force since 1 December 2012.

This standard specifies the general technical requirements for remanufacturing of mechanical products. This standard applies to the remanufacturing of mechanical products, and can also be used as a reference for the remanufacturing of other products.
