GB9706 Hydraulic Testing Machine

GB9706.1-2020Medical electrical equipment - Part 1: General requirements for basic safety and basic performance

If both of the following conditions are met simultaneously, the pressure vessel should be able to withstand the hydrostatic test pressure:

Complies with clause 9.7.5 of GB9706.1-2020 "Medical Electrical Equipment Part 1: General Requirements for Basic Safety and Basic Performance" standard;

2、 Test requirements:

-Pressure greater than 50kPa; and

-The product of pressure and volume of a pressure vessel is greater than 200 kPa · 1

Use the following tests to verify compliance with requirements:

The hydrostatic test pressure should be the maximum allowable working pressure multiplied by a coefficient obtained from Figure 32.

Gradually increase the pressure to the specified test value and maintain this value for 1 minute.
