How should the inspection requirements for the airtightness test be specified on the drawings?

GB150 stipulates that when a gas-tightness test is required, the test pressure, test medium, and inspection requirements shall be specified in the drawings. The first two items are fine, but as for how to write that inspection requirement and what the basis for it is, none of the drawings I’ve seen include such information. Does anyone know?
First 10%, then to 50%, and gradually 10% at a time up to 100%
Thank you! However, what the guy provided are probably the steps for a pressure test; what I want to ask about are the inspection requirements for a leak test.
The airtightness test is used to evaluate the sealing performance of containers, focusing on the sealing quality of the sealing surfaces and welds. It can be conducted using soapy water; no leakage indicates that the container meets the requirements
