We should have the quality certificate of materials from manufactory and approved by classification society, otherewise the materials can be used after being re-inspection in presence of surveyor according to classification society relation requirement.1.3在合同规定的图样、技术文件和本标准中未注明技术要求的产品或零部件，均按中华人民共和国国家标准，或相应的专业标准（部标准）、企业标准的要求或工厂惯例进行。As for the technological requirement of these products and accessory which not mentioned in the draft and technologic document of contract relgulation, then the draft、technologic document and this standard, must be subjected to PRC standard, or relative professional standard (department standard)、requirement of enterprise standard and factory convention.1.4对各种试验方法，本标准不作详细规定，除另有规定外一般可按工厂的技术文件进行。系泊与航行试验按中华人民共和国国家标准，及船东与验船师认可的系泊机航行试验大纲进行。The various test methods are not included in this standard. In general, test should be implement according to the technological documents of the factory, except additional requirement. Mooring test and sea trial is to be carried out according to national standard and outline of mooring test and sea trial approved by Owner and supervisor.1.5对批量建造的船舶，其倾斜试验、系泊试验及航行试验的项目，在船东和验船师认可的情况下，可从第二艘船起适当减少。For a set of ships constructions, the items of inclining test, mooring test and sea trial may properly reduce from second vessel under the approval by Owner and supervisor.2. 检验与建造Inspection and construction2.1船东在按本标准规定进行检查、验收时，对本标准未作规定的专用设备的检查、验收，可事先与本公司协商决定。The Owner takes an inspection and acceptance to the equipment according to this standard, as for the inspection and acceptance of the special equipment that not mentioned in this standard, Owner should discuss to decide with us before inspection and acceptance.2.2除规定每周按检验计划执行检验任务外，本公司还可用书面要求船东到场检验，一般应在隔日提出需检验的项目、时间和地点。We can also ask Owner to be present for inspecting in written, except regular inspection according to inspection plan of weekly. In general, we should supply inspection item, time and place in advance by one day.船东现场检验期间，本公司应提供所有保证实施检验的条件。During the inspection in presence of surveyor on the spot, we should ensure the inspection condition in good order.船东应在指定的时间和地点进行检验。事先接到本公司检验通知未表示异议，而届时又未到现场，则验船师或本公司验收合格后即认为所检验项目有效。The inspection should be taken in appointed time and place for owner If Owner has no objection about the notice sent by us before inspection, but he is absent for the inspection due to himself. So the inspection item will be considered effective after approved by supervisor or us.2.3本公司应与船东紧密地联系，向船东提供详细的造船进度、试验项目和试验程序等资料。船东在检验中发现问题，应及时向本公司提出。We should be frequently touch with Owner.

Owner should point it out to us in time3. 转包设备Subcontract equipment3.1在规定的检验项目内，对船东选定需要检验的转包设备，本公司应将制造厂预定的试验或检查的时间、地点通知船东。In regular inspection item, we should notified Owner about the planned test or inspection time and place of the subcontract equipment which are chosen for inspection by Owner.如果本公司认为制造厂的质量保证体系完善，所提供的设备符合质量要求，则可建议船东免除参加制造厂对所提供设备的试验和检查。但本公司需向船东提供制造厂设备出厂合格证或产品证书。If the manufactorys quality guarantee system is considered complete and the supplied equipment accod the quality requirement, there is no need for Owner to test and inspect the equipment at the manufactory. In this case, we need to provide certificate or certificate of product at manufactory.3.2 转包设备应符合船级社规范的要求或相应的国家标准、专业标准（部标准）、企业标准及本标准的规定。Subcontract equipment should be in accordance with classification society requirement, relative national standard, professional standard (department standard), requirement of enterprise standard and this standard4. 无损检查Non-destructive test4.1一般要求General requirement4.1.1无损检查的项目，应符合船级社规范、技术规格书和本标准的规定。Non-destructive test item should be in accordance with classification society rules, technical specification and this standard4.1.2船级社规定需作无损检查的材料，原则上应在制造厂进行，并出具有关证书。The materials are needed to take no-destruction test according to classification society requirement. This test should be taken in the manufactory in principle, and the certificate should be issued at the same time.4.1.3对要求作无损检查的物件，凡在图样上没有标注者，船厂可按惯例进行。If there are no marks on the objects that require to be taken non-destructive test, the shipyard can carry out the test according to the usual practice.4.2 无损检查要求Requirement of non-destructive test4.2.1船厂应按船级社规范及已批准的图样对焊缝进行射线探伤检查。射线探伤标准可按船级社规范或相应标准的规定。The shipyard should carry out the x-ray defection on welding seam according to classification society rules and approved design. The standard of x-ray defection should in accordence classification society rules or relative standard.4.2.2根据需要，可用超声波探伤检查代替射线探伤检查，亦可采用磁粉法、着色渗透法，或其他方法进行探伤检查。Based on situation, ultrasonic defection may be used instead of x-ray defection. Magnetic test, penetration colored and other methods also may be adopted.第一篇 建造精度Chapter 1 Construction Accuracy范围Notes本标准适用于以柴油机为动力常规钢质海船的建造，对于专业性的。特殊用途及内河运输的船舶可参照使用。This standard applies mainly to the conventional sea-going steel ship driven by diesel plant.
