c. 測試:取一個新的大PE袋剪開,將PE袋內側覆蓋于管口并用管帽封堵管口一側(或在管口外側套PE袋用潔凈膠帶加固);將上述b步驟中的測試樣倒入管中,用同樣的方法封堵管口另一側(或在管口外側套PE袋用潔凈膠帶加固),并將短管搖晃5分鐘。
Testing: Take a new big PE bag and cut it, cover the inside of the PE bag with the pipe and seal the side of the pipe with the cap (or use PE bag tape on the outside of the pipe to be reinforced with clean tape); pour the sample in step b above into the pipe, and use the same method to block the other side of the pipe (or use a PE bag on the outside of the pipe to be reinforced with clean tape), and shake the short pipe for 5 minutes.

Testing Sampling: Pour the shaken material in the short pipe into a metal sample bag, a carbon sample glass jar and a boron sample bag, get a set of test samples and remarks.
e. 將所有樣品送至實驗室檢測。(優先檢測金屬,金屬數據不合格,將管道直接退回;金屬數據合格,則進一步檢測碳硼樣,合格則接受,不合格則退回。)
Send all samples to the lab for testing. (Priority test for metal, if the metal data is unqualified, the pipeline will be returned directly; if the metal data is qualified, the carbon and boron sample will be further tested, if it’s qualified, it will be accepted; if it’s not, it will be returned.)

After the first acid rinsing, the metal test data is unqualified. Rinsing the short pipe with acid for 10-15 minutes (HF: HNO3 = 1: 8, Acid: water = 1: 3), and then repeat steps a-e above. If the metal data is qualified, the carbon and boron samples will be further tested, if it’s qualified, it will be accepted; if it’s not, it will be returned.
