8、bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizat
9、ions, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in th
10、e ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of
11、the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 10228 was prepared by Technical Committee ISO/TC 83, Sports and
12、 recreational equipment, Subcommittee SC 4, Snowsports equipment. This second edition cancels and replaces the first edition (ISO 10228:1991), which has been technically revised.

13、bility of measurement data, which are determined by the manufacturer or other institutions by testing the binding mounting area of cross-country skis.

14、t screws 1 Scope This International Standard specifies the dimensions, mechanical properties and fastening characteristics of test screws used for testing the binding mounting area of cross-country skis. 2 Normative references The following referenced documents are indispensable for the application
15、of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

17、re the comparability of measurement data 4 Designation Test screws in accordance with this International Standard shall be designated by: a) the words “Test screw”; b) the reference to this International Standard, i.e. ISO 10228; c) their nominal dimensions, i.e. diameter length. EXAMPLE Test screws
18、 with a nominal diameter of 6,3 mm and a length of 18 mm would be designated: Test screw ISO 10228 6,3 18 BS ISO 10228:2011ISO 10228:2011(E) 2 ISO 2011 All rights reserved5 Requirements 5.1 General The strength requirements and typical application characteristics of cross-country ski-binding test sc
19、rews shall be tested in accordance with ISO 7795. 5.2 Materials Test screws shall be made of steel as specified in ISO 2702, which shall comply with the additional requirements in 5.4 and 5.5 of this International Standard. 5.3 Dimensions 5.3.1 Screw head Test screws shall be cross recess type Z No.
20、 3 with a recommended minimum penetration depth of 2,72 mm to 3,18 mm (see ISO 4757). If screws having countersunk heads are used, the angle of countersinking 2090+ is recommended. 5.3.2 Thread and end configuration The cross-section of the test screw may be circular or non-circular within the major
21、 diameter of 00,156,3 mm mm(see Figure 1). The thread length shall be at least 1 mm longer than the penetration depth, irrespective of the shaft length. The tolerance on the length of the screw shall be 0,6 mm. The shaft end shall correspond to Figure 1. 5.4 Surface Test screws shall be coated or pl
22、ated with materials which provide adequate protection against corrosion and ensure a reproducible coefficient of friction. For example, a suitable coating would be a zinc electroplated coating, Fe/Zn 5c (see ISO 4042), having a clear chromate conversion coating and a minimum local thickness of 5 m (
23、batch average 4 min., 6 m max.), when measured on the top surface of the screw head. During electroplating, adequate precautions shall be taken to avoid hydrogen embrittlement. 5.5 Application characteristics 5.5.1 General The specified fastening and mounting characteristics of the test screw shall
24、be based on a uniform drill diameter of 0,1503,6 mm mm.+5.5.2 Strength requirements The breaking moment for test screws under a torque of the same axis and direction as the driving torque shall be not less than 10 Nm. The screws shall not break when subjected to the conditions of the ductility test.
