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.

　　鋼筋取樣規范之熱軋帶肋鋼筋。每批由同一牌號、同一爐罐號、同一規格的鋼筋組成。每批重量通常不大與60t。每批鋼筋應做兩個拉伸實驗、兩個彎曲試驗。超過60t的部分，每增加40t（或不足40t的余數），增加一個拉伸試樣和一個彎曲試樣。

　　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).

　　熱軋光圓鋼筋每批由同一牌號、同一爐罐號、同一規格的鋼筋組成。每批重量通常不大與60t。每批鋼管應做兩個拉伸實驗、兩個彎曲試驗。超過60t的部分，每增加40t（或不足40t的余數），增加一個拉伸試樣和一個彎曲試樣。

　　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).

　　鋼筋取樣規范之余熱處理鋼筋，每批由重量不大于60t的同一牌號、同一爐罐號、同一規格、同一交貨狀態的鋼筋組成。每批鋼筋應做兩個拉伸實驗、兩個彎曲試驗。

　　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.

　　碳素結構鋼每批由重量不大于60t的同一牌號、同一爐罐號、同一等級、同一品種、同一尺寸、同一交貨狀態的鋼筋組成。用《碳素結構鋼》（GB/T700—2006）驗收的直條鋼筋每批應做1個拉伸實驗、1個彎曲試驗。

　　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).

　　冷軋鋼筋每批由同一牌號、同一外形、同一規格、同一生產工藝和同一交貨狀態的鋼筋組成、每批不大于60t。逐盤或逐捆做一個拉伸實驗，牌號CRB550每批做兩個彎曲試驗，CRB650批號及以上每批做兩個反復彎曲試驗。

　　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.
