BS 541:2006 pdf download – Aluminium and aluminium alloys — Rolled products for cans, closures and lids — Specifications e) quantity: mass, area or number of pieces; f) any requirements for inspection documents; g) any special requirements for packaging: mass per coil and per packaging unit; number of sheets per stack; position of coil axis (vertical or horizontal); direction of winding (see Clause 10); design of pallet; h) any special requirements agreed between supplier and purchaser: marking of products; flagging of joints. 4.2 Requirements 4.2.1 Production and manufacturing processes Unless otherwise specified in the order, the production and manufacturing processes shall be left to the discretion of the manufacturer. Any changes in the processes for subsequent and similar orders which significantly affect the properties of the product, whether or not specified in this standard, shall be agreed by the purchaser. 4.2.2 Quality control The supplier shall be responsible for the performance of all inspection and tests required by this European Standard and/or the particular specification prior to the shipment of the product. 4.2.3 Chemical composition The chemical composition shall comply with the requirements as specified in EN 573-3 and for alloy EN AW-5006 as specified in Annex D and EN 602. 4.2.4 Freedom from defects The product shall be free from defects prejudicial to its suitable and proper use. 4.3Test procedure4.3.1Sampling 4.3.1.1 Samples for chemical analysis Sampling shall be carried out at the time of casting according to EN 14361.The average content of eachsample shall be within the specification for the chemical composition. NOTE EN 14361 includes criteria for how to determine the number, volume and shape of samples, the time and loca-tion of sampling and the design and maintenance of the tools, in order to make sure that the average chemical composi-tion of the sample represents the average chemical composition of the whole melt. 4.3.1.2Specimens for mechanical testing 4.3.1.2.1 Number of specimens Unless otherwise specified, at least one specimen shall be taken from each master coil of an inspection lot.4.3.1.2.2Location and size Specimens shall be taken from samples in such a way that it is possible to orientate the test pieces parallelwith the rolling direction (longitudinal direction). The specimens shall be sufficiently large enough to allow the manufacture of the test pieces necessary tocarry out the required tests and shall include sufficient metal to allow the manufacture of test pieces for anyretests required. 4.3.1.2.3ldentification of specimens Each specimen shall...
