c. 测试：取一个新的大PE袋剪开，将PE袋内侧覆盖于管口并用管帽封堵管口一侧（或在管口外侧套PE袋用洁净胶带加固）；将上述b步骤中的测试样倒入管中，用同样的方法封堵管口另一侧（或在管口外侧套PE袋用洁净胶带加固），并将短管摇晃5分钟。

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.

d. 测试取样：将短管中摇晃过的料分别倒入1个金属取样袋、1个碳样玻璃瓶和1个硼样袋，得到一组测试样并备注。

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. 将所有样品送至实验室检测。（优先检测金属，金属数据不合格，将管道直接退回；金属数据合格，则进一步检测碳硼样，合格则接受，不合格则退回。）

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.)

2. 碳化硅套管

Silicon Carbide Sleeve

a. 吹扫：用高压氮气吹扫测试短管3-5分钟，然后将短管放置于1号洁净室缓冲区备用，尽可能保证管道清洁不受污染。

Purge: Purge the test short pipe for 3-5 minutes with high-pressure nitrogen, and then place the short pipe in the buffer zone of cleaning room 1 for spare use, as far as possible to ensure that the pipeline is cleaning.

b. 取样：

EGPH种晶线取样：取一个金属样，作为对照样并备注；另取一个大PE袋，取1/2袋的样品作为种晶金属测试样品

Sampling: EGPH seed line, take a metal sample as a reference sample and remarks; take another big PE bag and take 1/2 bag of seed for testing.

EGPH正常产品处理线取样：分别取碳样、硼样各一个，作为对照样并备注；另取一个大PE袋，取1/2袋的样品作为碳硼测试样品。(Samples must from the same FIBC)

Sampling: Take metal sample、carbon sample、boron sample each one respectively from the EGPH line, these samples regard as a reference sample and remarks; take another big PE bag and take 1/2 bag of product for testing.(Samples must from the same FIBC)
