Acceptance criteria  \n(1) Testing of mechanical couplers should be in accordance with Code of Practice for Structural Use of Concrete.  \n(2) Testing of mechanical couplers by accredited laboratories should be in accordance with PNAP APP-118.  \n(3) Mechanical couplers should comply with Code of Practice for Structural Use of Concrete.  \n(4) Installation of mechanical couplers should be strictly in accordance with the manufacturer’s specifications/recommendations.  \n(5) The following documents should be included in the submission for checking:  \nMechanical couplers for steel reinforcing bars without ductility requirement:  \n(a) Quality control documentation relating to the production of the mechanical couplers. This should include specifications for the couplers, the constituent materials used to manufacture the coupler, and the steel reinforcing bars used with the coupler in the final assembly, description on the manufacturing processes, labeling of the coupler to ensure traceability and quality control, description of the test procedures, and the conditions of acceptance, for incoming materials and for in-process and/or final product testing, etc. Documents should also be submitted to prove  \nthat manufacturing of the couplers and the process of any strength hardening and threading of the connecting ends of steel reinforcing bars are by a factory or factories with ISO 9001 quality assurance certification,  \n(b) Calculations to justify the structural adequacy of the couplerand the connecting ends of the steel reinforcing bars.  \n(c) Sample mill certificates of the constituent materials used to produce the couplers.  \n(d) Test results should be submitted to establish that criteria as specified in clause [3.2.8.3](3.2.8.3) of the CoP for Structural Use of Concrete 2013 are complied with. The tests should be carried out by laboratories accredited under the HOKLASor other laboratory accreditation bodies which have reached mutual recognition agreements/arrangements with the HOKLAS for the particular tests concerned.  \nMechanical couplers for steel reinforcing bars with ductility requirement:  \n(e) Calculations to justify the structural adequacy of the couplerand the connecting ends of the steel reinforcing bars should  \nbe included in structural submission,(f) Information in respect of quality control:  \n(i) Name of the coupler including model number, if applicable;  \n(ii) All relevant specifications for the coupler, the components and/or constituents used to manufacture the coupler, and the steel reinforcing bars used with the coupler in the final assembly;  \n(iii) Place where the coupler and components are manufactured. If the manufacturing of a portion of the process or supply of a component is by another company, description should be made on how those components or portions of the process can comply with the manufacturer’s specifications;  \n(iv) Brief description of the manufacturing process. A flowchart would be helpful;  \n(v) Description of the test procedures, and the conditions of acceptance, for incoming materials and for inprocess and/or final product testing;  \n(vi) Name of the inspection agency; and  \n(vii) Description of how the coupler is labelled. The labelling system should provide a means to trace the coupler back to the production and quality control records at the manufacturing facility;  \n(g) Documents in respect of quality control:  \n(i) Documents to prove that manufacturing of the couplers and the process of strength hardening and threading of the connecting ends of steel reinforcing  \nbars are by a factory or factories with ISO 9001 quality assurance certification;  \n(ii) Test results to establish that the splicing assemblies comply with the requirements of Type 2 mechanical couplers as specified in ","cbCaidfR7KOazxyu","https://ap.wps.com/l/cbCaidfR7KOazxyu","pdf",831850,35,"English","# A.
