Through the leak-rate comparison with PTB using standardleak, the reliability of uncertainty evaluation results has been verified.
通过传递标准漏孔与德国PT B开展了漏率比对,验证了测量不确定度评估结果的可靠性。

In the following test cycle the standardleak will be connected through the chamber at that moment where the test sample will be filled with test pressure.
在测试中,标准泄漏此时将接到气室,而气室内的试件就充满了测试压力。测试结束时,结果就显示在屏幕上。

The standard covers dimensions and gaging of plastic tapered National Pipe Threads (NPT) for leak-tight joints, and it is now referenced in all ASTM Standards for plastic piping products.
