Manufacture5.1 The tube shall be produced by drawing an extruded tube made from hollow extrusion ingot (cast in hollow form or pierced)and extruded by use of the die and mandrel method.6. Responsibility for Qua
38、lity Assurance6.1 Responsibility for Inspection and TestsUnless otherwise specified in the contract or purchase order, the producer isresponsible for the performance of all inspection and test requirements specified herein. The producer may use his own or any othersuitable facilities for the perform
39、ance of the inspection and test requirements specified herein, unless disapproved by the purchaserin the order or at the time of contract signing. The purchaser shall have the right to perform any of the inspections and tests setforth in this specification where such inspections are deemed necessary
40、 to assure that material conforms to prescribed requirements.6.2 Lot DefinitionAn inspection lot shall be defined as follows:6.2.1 For heat-treated tempers, an inspection lot shall consist of an identifiable quantity of material of the same mill form, alloy,temper, and thickness traceable to a heat-
41、treated lot or lots, and subjected to inspection at one time.4Available from Standardization Documents Order Desk, Bldg. 4 Section D, 700 Robbins Ave., Philadelphia, PA 19111-5098.4Available from Aluminum Association, Inc., 1525 Wilson Blvd., Suite 600, Arlington, VA 22209, http:/www.aluminum.org.5A

Chemical Composition7.1 LimitsThe tube shall conform to the chemical composition limits in Tab
45、le 1. Conformance shall be determined by theproducer by analyzing samples taken at the time the ingots are poured, or samples taken from the finished or semi-finished product.If the producer has determined the chemical composition of the material during the course of manufacture, he shall not be req
46、uiredto sample and analyze the finished product. . Conformance shall be determined by the producer by analyzing samples taken at thetime the ingots are poured in accordance with E716 and analyzed in accordance with E607, E1251, E34 or EN 14242. At least onesample shall be taken for each group of ing
47、ots poured from the same source of molten metal. If the producer has determined thechemical composition of the material during the course of manufacture, he shall not be required to sample and analyze the finishedproduct.NOTE4It is standard practice in the United States aluminum industry to determin
48、e conformance to the chemical composition limits prior to furtherprocessing of ingots into wrought products. Due to the continuous nature of the process, it is not practical to keep a specific ingot analysis identified witha specific quantity of finished material.7.2Number of SamplesThe number of sa
49、mples taken for determination of chemical composition shall be as follows:7.2.1When samples are taken at the time the ingots are poured, at least one sample shall be taken for each group of ingots pouredsimultaneously from the same source of molten metal.7.2.2When samples are taken from the finished or semi-finished product, a sample shall be taken to represent each 2000 kg, orfraction thereof, of material in the lot, except that not more than one sample shall be required per piece.7.3Methods of SamplingSamples for determination of chemical
