11、ding screws Test methods DIN ISO 10228:2011-10 4Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each m
12、ember body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
13、Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards a
14、dopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of 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 p

20、 is used for testing the binding mounting area to ensure 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
21、 dimensions, i.e. diameter length. EXAMPLE Test screws with a nominal diameter of 6,3 mm and a length of 18 mm would be designated: Test screw ISO 10228 6,3 18 DIN ISO 10228:2011-10 75 Requirements 5.1 General The strength requirements and typical application characteristics of cross-country ski-bin
22、ding test screws 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 reces
23、s type Z No. 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 with
24、in the major 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
25、coated or plated 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 thickn
26、ess of 5 m (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
27、screw shall 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 duc
28、tility test. DIN ISO 10228:2011-10 85.5.3 Fastening characteristics The mean static pull-out resistance shall correspond to at least that of a reference screw complying with the requirements of ISO 1478, type F, and having a nominal diameter of 6,3 mm.
