Search on Baidu: Air tightness test of hydrogen system per week - weekly closed light test
pneumatic sealing test
I suggest changing “per week” to “weekly”; I’m not sure why, but I think PER implies something quantitative. .
“per week” is more accurate; “weekly” can be understood to mean about a week or so, as you said, it’s not a precise figure
The term \"air tightness test\" seems inappropriate here
pressure leak check
weekly leakage test for hydrogen system
The term “weekly pneumatic sealing test per week” generally refers to the overall time period of “each week,” rather than meaning that the test is carried out once per week. Therefore, if we say that the airtightness test is performed once a week, we should specify it as \"test once per week\"; if it is done twice a week, then it should be specified as \"test twice per week\". Weekly generally refers to once a week. Weekly meeting = regular weekly meeting ； Weekly test = an experiment once a week.
