29、ed in millimetres and specified by the purchaser NOTE It is the basis for the determination of the values of all the characteristics of the wire for acceptance purposes. BS EN 10264-1:2012EN 10264-1:2012 (E) 5 3.2 actual diameter arithmetic mean of the perpendicular measurements on one section, in a

30、ccordance with EN 10218-1 3.3 out of roundness arithmetic difference between the maximum diameter and the minimum diameter measured perpendicularly on one section of wire 4 Information to be supplied by the client In the order, the purchaser shall specify clearly the product, the delivery conditions

31、 and the type of inspection document to be supplied. The product is clearly defined by the designations described in EN 10264 parts 2, 3 and 4. For a clear definition of a delivery of rope wire, the following additional information should be given: mass and length of delivery (total mass); unit mass

32、; type of packaging. 5 Characteristics of and requirements for wire 5.1 Diameter tolerances All the diameter values measured in accordance with EN 10218-2 on one section of wire shall be within the tolerance limits given in the respective tables. The level of tolerance corresponds to level T4 of EN

33、10218-2 for drawn wire and level T1 for class A coated wire. The out of roundness shall not be greater than half the tolerance specified in the respective tables referred to in EN 10264 parts 2, 3 and 4. 5.2 Tensile strength 5.2.1 Tensile strength grade - permitted variations The tensile strength gr

34、ades are specified in EN 10264 parts 2, 3 and 4. Additional grades are possible by agreement between supplier and user at the time of order. All other mechanical property requirements are for the next highest tensile grade. These values are the lower limits for tensile strength of each grade. The pe

35、rmitted upper limit for non alloy steel wire for ropes for each grade shall not exceed the lower limit by a value greater than the values given in Table 1. BS EN 10264-1:2012EN 10264-1:2012 (E) 6 Table 1 Permitted tensile strength variations Nominal dimension wire diameter: d or profile: h Permitted

In the case of alloy steel wire for ropes, the maximum value shall not be greater than the m

37、inimum value plus 15 %. 5.2.2 Procedure for tensile test The tensile test shall be carried out in accordance with EN 10218-1. The loading rate may be greater than that specified in EN 10218-1, depending on the number of tests to be carried out for the batch inspection. However, it shall not exceed t

38、he rate corresponding to a 25 % elongation between anchorage heads in 1 min. In the event of a dispute, the tensile test shall be carried out strictly in accordance with EN 10218-1, in particular with regard to the loading rate. 5.3 Reverse bend test This test is specified for steel wire for ropes a

39、s specified in EN 10264 parts 2 and 3 with a diameter greater than 0,5 mm. It shall be carried out in accordance with EN 10218-1. If agreed between customer and supplier at the time of order, this test can be used for wires under 0,5 mm diameter; values for acceptance will be agreed between parties.

40、 5.4 Torsion test This test applies only to non alloy steel wire, of diameter greater than or equal to 0,5 mm. It shall be carried out in accordance with EN 10218-1. The wire shall show no signs of breaking for a minimum number of turns as specified in EN 10264 parts 2 and 3. If agreed between custo

41、mer and supplier at the time of order, this test can be used for wires below 0,5 mm diameter; values for acceptance will be agreed between parties. 5.5 Tensile test on knotted wire This test replaces the alternate bending and torsion tests for dimensions below 0,50 mm. It is a tensile test on a wire

42、 with a simple knot in the middle. This test shall be carried out in accordance with EN 10218-1 and the result shall be greater than or equal to 50 % of the nominal strength specified. BS EN 10264-1:2012EN 10264-1:2012 (E) 7 5.6 Coatings The coatings generally used are zinc and zinc alloy. The stand

43、ard coatings shall be classes A and B in accordance with EN 10244-2. If another class of coating is requested or if other metallic coatings are required, these shall be the subject of agreement at the time of ordering. The coating method is not specified. The class of the coating is defined by the m

44、inimum mass per unit of surface area (usually g/m2) and its adherence. The mass of coatings shall be in accordance with the requirements specified in EN 10264 parts 2 and 3. 6 Inspection documents In accordance with the purchasers order, inspection documents shall be drafted in accordance with EN 10

45、204. 7 Sampling and compliance criteria These parameters shall satisfy the requirements of EN 10021. If the rope manufacturer wants acceptance tests to be carried out, the sample sizes and acceptance criteria shall be in accordance with the minimum requirements of Table 2 unless otherwise specified

46、by agreement between the purchaser and the supplier. To ensure representative sampling, the samples shall be taken at random. Usage of statistical methods is recommended, in order to reduce the number of tests required. If the number of non-complying results is greater than that defined in the 3rd c

47、olumn of Table 2, all the units (product units) shall be 100 % inspected, but only with regard to the defective characteristic(s). If one or more of these new tests prove unsatisfactory, the non-complying units shall be rejected. The acceptance or rejection of a non-complying batch shall be decided

48、by agreement between the parties involved.
