3.1 Type testing of mechanical properties
3.1.1 General Each design shall conform to the requirements of Clause 2.4. NOTE 1 The test of each design is known as the type test, which determines the adequacy of the design for achieving the required performance. NOTE 2 Each change in manufacturing process, grade of material, design, and size necessitates separate type testing, to demonstrate conformance with the requirements of Clause 2.4. NOTE 3 In addition to type testing, effective quality control necessitates systematic testing of each lot to ensure continuing conformance with the requirements of Clause 2.4. 3.1.2 Test for deformation Each design shall be tested in accordance with the relevant requirements of Appendix G, and shall sustain the manufacturing axial proof force specified for the component in Table ..2. Following the removal of the force, the dimensions shall conform to the manufacturer’s specifications. Permanent set shall conform to Clause 3.4[b] after the manufacturing proof force has been applied and removed as described in Clause 3.2.2. 3.1.3 Type test Each design shall be tested to destruction in accordance with Appendix G. in both axial and transverse. Each sample shall have a breaking force at least equal to the minimum value specified for the component in Table 2.2. After testing to destruction, fractured members shall exhibit permanent set before fracture. NOTE This test may be carried out on the same components subjected to the deformation test. 3.1.4 Testing for transverse strength Tests shall be carried out to ensure conformance with the working loads for transverse loading (refer Figure G.1]). 3.1.5 Test samples The number of samples selected for testing shall be determined in accordance with Clause H.4 and shall not be less than one for each design for each test.
3.2 Manufacturing tests
3.2.1 Manufacturing examination All finished components shall be visually examined for conformity to the requirements of Clauses 2.3. 3.2.2 Manufacturing proof test Collared eyebolts and eyenuts in their finished condition (except they may be painted or unpainted) shall, where required by Appendix H and under the conditions specified in Clause G.3, be subjected to a proof force at least equal to the manufacturing proof force specified in Table 2.2. After removal of the force, there shall be no visible defects, and the permanent set shall conform to Clause 3.4(b). 3.2.3 Non-destructive test Where required by Appendix H, the forged surfaces of collared eyebolts and eyenuts, shall, after heat treatment and de-scaling, be subjected to magnetic particle or dye penetrant examination in accordance with AS 1171 or AS 2062 [or international equivalent). Any such examination shall be undertaken by operators qualified in accordance with AS ISO 9712 (or international equivalent). Indications greater than 2 mm in length shall not be permitted in areas of the collared eyebolts and eyenuts subjected to tensile stresses, in all foreseeable service conditions. Where grinding is required to remove such indications then, after grinding, the collared eyebolts and eyenuts shall conform to the dimensions and tolerances specified by the manufacturer. A final examination shall show no indications greater than 2 mm in length in areas subject to tensile stresses, in all permissible service conditions. NOTE Care should be taken to ensure that the direction and roughness of grinding does not create starting points for fatigue failure and cause excessive heating, which may have a local effect on the heat-treated condition, or may cause cracks. 3.3 Proof loading Where required by the customer or user, each eyebolt and eyenut shall be subjected to a force that is not less than the relevant minimum proof test force specified in Table 2.2 applied under the conditions specified in Appendix G.
