When we test the quality of reinforcing bars, we will certainly not say that all batches will be sent for inspection. First, it is a waste of time and second, it is inefficient. Today, we will introduce to you how the quantity and batch of samples are stipulated in the code for reinforcing bars sampling.

　　钢筋取样规范之热轧带肋钢筋。每批由同一牌号、同一炉罐号、同一规格的钢筋组成。每批重量通常不大与60t。每批钢筋应做两个拉伸实验、两个弯曲试验。超过60t的部分，每增加40t（或不足40t的余数），增加一个拉伸试样和一个弯曲试样。

　　Hot rolled ribbed steel bars in the Code for Reinforcement Sampling. Each batch consists of steel bars of the same brand, the same tank number and the same specification. Each batch usually weighs less than 60 tons. Two tensile tests and two bending tests should be done for each batch of reinforcing bars. For the part over 60 t, a tensile specimen and a bending specimen are added for each additional 40 t (or less than the remainder of 40 t).

　　热轧光圆钢筋每批由同一牌号、同一炉罐号、同一规格的钢筋组成。每批重量通常不大与60t。每批钢管应做两个拉伸实验、两个弯曲试验。超过60t的部分，每增加40t（或不足40t的余数），增加一个拉伸试样和一个弯曲试样。

　　Each batch of hot rolled bars consists of bars of the same brand, the same furnace tank number and the same specification. Each batch usually weighs less than 60 tons. Two tensile tests and two bending tests should be done for each batch of steel tubes. For the part over 60 t, a tensile specimen and a bending specimen are added for each additional 40 t (or less than the remainder of 40 t).

　　钢筋取样规范之余热处理钢筋，每批由重量不大于60t的同一牌号、同一炉罐号、同一规格、同一交货状态的钢筋组成。每批钢筋应做两个拉伸实验、两个弯曲试验。

　　Each batch of waste heat treatment steel bars in the code for steel bar sampling consists of steel bars of the same brand, the same furnace tank number, the same specification and the same delivery status with a weight of not more than 60 tons. Two tensile tests and two bending tests should be done for each batch of reinforcing bars.

　　碳素结构钢每批由重量不大于60t的同一牌号、同一炉罐号、同一等级、同一品种、同一尺寸、同一交货状态的钢筋组成。用《碳素结构钢》（GB/T700—2006）验收的直条钢筋每批应做1个拉伸实验、1个弯曲试验。

　　Each batch of carbon structural steels consists of steel bars of the same brand, the same tank number, the same grade, the same variety, the same size and the same delivery status, which weigh no more than 60 tons. One tensile test and one bending test should be done for each batch of straight bars accepted by "Carbon Structural Steel" (GB/T700-2006).

　　冷轧钢筋每批由同一牌号、同一外形、同一规格、同一生产工艺和同一交货状态的钢筋组成、每批不大于60t。逐盘或逐捆做一个拉伸实验，牌号CRB550每批做两个弯曲试验，CRB650批号及以上每批做两个反复弯曲试验。

　　Each batch of cold-rolled steel bars is composed of steel bars of the same brand, shape, specification, production process and delivery status. Each batch is not more than 60 tons. Make a tension test one by one or one by one, CRB550 do two bending tests in each batch, CRB650 batch and above do two repeated bending tests in each batch.
