In the case of coils, the retest specimens
32、shall be taken from a distance of at least one lap away, but with a maximum of 20 m from the end of the coil. 7.7 Inspection documents If agreed at the time of ordering, one of the inspection documents specified in EN 10204 shall be supplied. 8 Marking A label shall be attached to each coil or bundl
33、e containing at least the following information: name or mark of the manufacturers works; full designation (see 4.2); nominal dimensions of the product; identification number; order number; mass of the coil or bundle. 9 Packing If not otherwise agreed at the time of ordering the packing requirements
34、 for the product shall be left at the discretion of the supplier. 10 Storage and transportation 10.1 Moisture, in particular condensation between the sheets, laps of the coil or other adjacent parts made of hot-dip zinc-aluminium coated flat products can lead to the formation of corrosion products.
35、The possible types of surface protection are given in 5.5. However if there is lengthy contact with moisture the protection may be reduced locally. As a precaution, the products should be transported and stored dry and protected from moisture. 10.2 During transportation, dark spots may appear on the
36、 coated surfaces as a result of friction. Generally, they only impair the appearance. Friction is reduced by oiling the products. However, the following precautionary measures should be taken: secure packing, laid flat, no local pressure spots. 11 Disputes EN 10021 is applicable to disputes after de
37、livery and their settlement. 12 Information to be supplied by the purchaser The following information is required from the purchaser so that the manufacturer may supply the products to conform with the requirements of this standard: a) product type (strip, sheet, cut length); b) nominal dimensions (
38、thickness, width and, in the case of sheet and cut lengths, length); c) quantity; d) complete designation (see 4.2); e) limiting mass and sizes of the coils and individual bundles of sheets; f) any products desired with different coating masses on each surface (see 5.2.2); g) any low carbon steel pr
39、oducts suitable for the manufacture of a specific part (see 6.2.2); h) any products supplied free from coil breaks (see 6.4); i) any maximum or minimum value for the coating mass per product surface (see 6.6.2); j) notification of which surface has been inspected (see 6.8.1); k) any testing at the m
40、anufacturers works (see 7.1.1 and 7.1.2); l) any supply of an inspection document and type of document (see 7.7); m) any requirements for packing (see clause 9).

41、nex A (normative) Reference method for determination of the coating mass A.1 Principle The sample shall be at least 5 000 mm2 in area. Using a sample with a surface area of 5 000 mm2, the loss of mass in grams when the coating is dissolved, multiplied by 200, will represent the coating mass in grams
42、 per square metre of the product, including both sides. A.2 Reagent and preparation of the solution Reagent: Hydrochloric acid (HCl 20 = 1,19 g/cm3) Hexamethylenetetramine Preparation of the solution: The hydrochloric acid is diluted with deionized or distilled water in the ratio one part pure HCl t
43、o one part water (50 % dilution). Hexamethylenetetramine is then added, stirring, in the ratio of 3,5 g per litre of dilute hydrochloric acid solution. This prepared solution permits the execution of numerous successive dissolutions under satisfactory conditions of attack of the coating, both from t
44、he point of view of speed and accuracy. A.3 Apparatus Balance capable of weighing samples to an accuracy of 0,01 g. For the test, use a take-off device. A.4 Procedure The following operations are applied to each sample: a) if necessary, degrease the sample with an organic solvent which will not atta
45、ck the coating, then dry the sample; b) weigh the sample to an accuracy of 0,01 g; c) place the sample in the hydrochloric acid solution with hexamethylenetetramine inhibitor at ambient temperature (20 C to 25 C). Leave the sample immersed in the solution until the release of hydrogen ceases or only
46、 a few bubbles are released; d) after the attack, the sample is washed and brushed under running water, dried with a cloth and then by heating to around 100 C and cooled or dried by blowing with warm air; e) weigh the sample again to an accuracy of 0,01 g; f) determine the difference between the mas
47、s of the coated sample and that of the sample without its coating. This difference, calculated in grams, represents the mass m of the coating.
