The tightness of interior space in condition of a high speed train with its side door, side window closed called train air-tightness. The paper introduces the air tightness of the high speed train and the basic methods for air tightness testing. It also applies a constant pressure leak model to test and points out that the importance of air tightness for high speed train.

We have studied and analyzed status and metrological supervision of blood glucose monitors, individual devices for a person’s blood glucose level measurement. It has been indicated that nowadays blood glucose monitors like other individual devices for medical measurement are not allowed to be involved in telemedicine public service. This accounts for absence of metrological supervision with these measurement devices in telemedicine. In addition, the key problem is absence of safe methods and means of remote verificaition, calibration and transmission of measurement data to health care centers. The article offers a remote test method for blood glucose monitors using a number of resistors with values correlating with measured blood glucose level. The available method has been successfully trialed in real practice.
