test coupon

Generally, the procedure qualification test shall be carried out on the product, or on the relevant test coupon.

工艺评定试验一般应在产品上进行，也可在相应的试块上进行。

Renewal of qualification may be made for any process by welding a single test coupon of either plate or pipe, and by testing of that coupon as required by QW-301 and QW-302.

如需重新获得资质，则该焊工需要遵照QW-301和QW-302的要求，在一个板材附件试片，或一个管材附件试片上，进行焊接试验。

A Welding Procedure Qualification Record ( Form No.: FN09/ 02-02) is a record of the welding data used to weld a test coupon.

焊接程序检定记录（表号：FN09/02-02）为焊接数据记录文件，用于附体试片的焊接操作。

When flow velocity reaches 2.62 m/ s, the local corrosion is pitting corrosion and the protective corrosion product film can not form on the test coupon surface at the temperature of 100 ℃ and the CO_2 pressure of 0.03 MPa.

在流体速度为2.62m/s的情况下，温度为100℃、CO2分压为0.03MPa时，发生的局部腐蚀主要为点蚀，试样表面未能形成保护性腐蚀产物膜；

Consideration of Standard on Mechanical Properties Test of Welding Coupon of Pressured Equipment

对承压设备产品焊接试件的力学性能检验标准的思考

To test resistor R 1, first energize Ch. 1 to bias the test coupon.

若要测试电阻器R1, 首先激励通道1,向测试样板加电压.

The laboratory assessment tests showed that, at a concentration of 60 mg/ 1, the corrosion rate of test coupon was 0.029 mm/ yr and the cohesion rate was 4.32 mcm, which were at the best levels.

实验室评定表明：在药剂浓度为60mg/L的情况下，碳钢试样的腐蚀率为0.029mm，a，粘附速度为4.32mcm，均达到很好级；
