32、(normative) Notes to purchasers A.1 The following requirements shall be specified in tender invitations and in each order or contract: a) the grade designation of the alloy (see 4.3 and table 1); b) the total mass of the consignment; c) the form of the product (see 4.4); d) whether a certificate of

33、analysis is to accompany each consignment (see 6.3). A.2 The following requirements shall be agreed upon between the purchaser and the manufacturer: a) the method of manufacture (see 4.2); b) the limits for elements not given in table 1 (see 4.3); c) the method of chemical analysis (see 5.2.1); d) a

34、ny special packing requirements (see 6.1.2 and 6.1.4). Annex B (normative) Rounding-off rules When the results of chemical analysis are being recorded, the number that represents the result for any value specified in the standard shall be expressed to the same number of decimal places as the corresp

35、onding number in this standard. The following rounding-off rules shall be applied: a) When the figure immediately after the last figure to be retained is less than 5, then the last figure to be retained remains unchanged. b) When the figure immediately after the last figure to be retained exceeds or

36、 is equal to 5 and is followed by at least one figure other than zero, then the last figure to be retained is increased by one. c) When the figure immediately after the last figure to be retained is 5 and is followed by zeros only, then the last figure to be retained remains unchanged if even, and i

37、s increased by one if odd. SANS 711:2008 Edition 2.1 8 Annex C (informative) Quality verification of primary aluminium ingots for remelting C.1 When a purchaser requires ongoing verification of the quality of primary aluminium ingots for remelting, it is suggested that, instead of concentrating sole

38、ly on evaluation of the final product, he also direct his attention to the manufacturers quality system. In this connection it should be noted that SANS 9001 covers the provision of an integrated quality system. Amdt 1 C.2 If no information about the implementation of quality control or testing duri

39、ng manufacture is available to help in assessing the quality of a consignment, and a purchaser wishes to establish, by inspection and testing of samples of the final product, whether a consignment of the primary aluminium ingots complies with this standard, then a sampling plan based on acceptable s

40、tatistical tables should be agreed upon between the manufacturer and the purchaser.
