1. Material Requirement材料要求
1.1 Each patch of the rebar must be identified with tag, ex-shop quality certificate and test
report. The rebar delivered to the site shall be inspected as per the patch number and the diameter for acceptance. The acceptance includes tag and visual appearance inspection as well as random sampling for dynamic test in compliance with related codes. Only when the random sampling for dynamic test is qualified can the material be used. During the fabrication of rebar, if any abnormal phenomenon such as breaking, bad welding performance or distinct dynamics deficiency occurs, chemical component test or other special tests shall be performed.
钢筋应有出厂质量证明书和试验报告单，每捆（盘）钢筋均应有标牌。进场时应按炉罐(批)号及直径分批验收。验收内容包括检查标牌，外观检查，并按有关标准的规定抽取试样做力学性能试验，合格后方可使用。钢筋在加工过程中如发现脆断、焊接性能不良或力学性能显著不正常现象时，应进行化学成分检验或其它专项检验。
a) Electric welding or gas cutting are forbidden to be used for rebar sampling.

Execution Plan 执行计划 截取钢筋试样，严禁动用电焊，气焊切割。
b) The specification and brand of all the welding electrodes/wires must be in compliance with
the design requirement.
工程所有电焊条的规格、牌号，必须符合设计要求。
c) On site the delivered rebar must be kept by separately by the category, specification,
performance so as to prevent rusting and contamination.
钢筋进场后，必须按不同的品种规格、性能分别堆放，防止锈蚀和污染。
d) All the stacked rebar, products and by products must be labeled with indication of the
description, specification, quantity and where it is to be used with the aim of preventing mishandling and contamination by greasy contents.
堆放的钢筋及成品、半成品、必须逐一挂牌，标明其名、规格、数量及使用部位，以免发生差错，并防止油脂类污染。
1.6 Welding electrodes/wires shall be kept on the wooden (steel) shelf by the specification and
type so as to avoid moistening. The electrodes must be baking-treated before being used.
电焊条应分规格、牌号放置在木（铁）制的材料架上，不使其变潮，电焊条在使用前必须按规定进行烘陪处理。 2. Quality Criteria质量标准
