BS EN 2898:20084 1 Scope This standard specifies the performance and test requirements for corrosion and heat resisting solid steel rivets intended for aerospace applications. It applies whenever it is specified
16、 in the document defining the rivet. Its use, after agreement between the customer and the supplier, for solid rivets made from other materials, requires determination, case by case, of the minimum tensile and double shear loads. 2 Normative references The following referenced documents are indispen

21、 one material, batch from the same heat treatment furnace with the same surface treatment, and deriving from the same wire coil and the same place of manufacture The maximum mass of each batch is limited to 25 kg. 1) Published as ASD Prestandard at the date of publication of this standard. 2) Publis
22、hed as ASD Standard at the date of publication of this standard 3) In preparation at the date of publication of this standard. BS EN 2898:20085 3.2 rivet wire samples for test, each rivet batch shall be accompanied by rivet wire samples taken from each end of the coil used to manufacture the batch.
23、The samples shall be submitted to the same heat treatment as the rivets of that batch 3.3 rivet samples rivet samples intended for tests shall be chosen at random from each batch 4 Required characteristics The rivets shall conform with the requirements of the document defining the rivet and those pr
24、escribed in Table 1. Inspections and tests are to be carried out by the rivet manufacturer. Table 1 Technical requirements and test methods Subclause Characteristics Technical requirements Inspection and test methods Number of samples 4.1 Materials Shall conform with the requirements of the material
25、 standard quoted in the document defining the rivet. See material specification. 4.2 Dimensions Shall conform with the requirements of the document defining the rivet. Methods are at manufacturers option. In case of dispute, the projection method at 25 magnification for diameter of up to 8 mm and 10
26、 for diameter above shall be used as a reference method. The inspection shall be carried out at three equidistant points around the rivet. Table 2 4.3 Heat treatment Shall conform with the condition of use defined in the material standard. See 4.5. 4.4 Surface treatment Shall be in conformity with t
27、he defining document. Methods are at manufacturers option. 4.5 Mechanical properties Shall be checked either by a double shear test or by a tensile test combined with a hardness test. 4.5.1 Double shear Non-assembled rivets (i.e. without post-formed head) shall conform with the values specified in T
28、able 4. See EN 3238. If the rivets are not long enough for the double shear test, it shall be carried out on the wire samples. Table 3 4.5.2 Tension Rivet wire samples shall conform with the values specified given in Table 5. See EN 2002-001. Table 3 continued BS EN 2898:20086 Table 1 Technical requ
29、irements and test methods (continued) Subclause Characteristics Technical requirements Inspection and test methods Number of samples 4.5.3 Hardness Hardness values for rivet wire samples shall conform with the requirements of the corresponding material standard. Hardness values for rivets shall corr
30、espond with the rivet hardness values within a tolerance of 5 %. See EN 2002-7. Table 3 4.5.4 Upset test After upset the head of the rivet shall be free from cracks or folds when viewed at a magnification of 10. Rivets shall be placed in a test fixture substantially conforming to Figure 1 a). The fr
31、ee end of the rivet shall be upset using a flat tool to obtain a head conforming to the requirements of Figure 1b). Table 3 This test to be performed only at the request of the purchaser 4.6 Surface condition, appearance Rivets shall be free from seams, burrs, laps, crevices, incrustations, clefts,
32、tooling marks, scores, cracks and other defect prejudicial to the use of the rivet. Rivets shall be examined visually with or without magnification. Magnification is limited to 6. Table 2 4.7 Identification and marking Each rivet shall be marked in conformity with the defining document, except for p
33、articular indications requested by the customer. No sharp edges or other defect detrimental to the correct set ting of the rivet shall be present. Visual examination. 4.8 Packaging Rivets shall be delivered in strong and durable packages, capable of protecting them from physical and corrosive deteri
34、oration. Any particular or additional packaging requirements shall be specified in the order. If the rivets delivered come from different batches, each batch shall be packed and identified separately. Unless particularly specified in the order, the number of rivets in the same package is left to the
35、 manufacturers discretion. However, maximum mass is 25 kg. A copy of the manufacturers delivery note relating to the rivet batch shall be included in the package but may, on the other hand, be sent separately on request. continued BS EN 2898:20087 Table 1 Technical requirements and test methods (con
