Filter precision of voltage regulation box
Thread Content
The filtration precision of the voltage regulation box should not be lower than 50μm. How to understand it. Which is better, 40μm or 60μm?
This is a bit ambiguous. In terms of precision, 40um is clearly higher, while 60um is lower. It should not be less than 50um, which means the precision is greater than or equal to 50um; therefore, 40um is **acceptable. So. . . . . .
The logic is correct. But the literal interpretations seem inconsistent.
You are right. This topic is derived from clause 5.1.6 of \"CJ/T 275-2008 Urban Gas Regulating Boxes\": the filtration accuracy of regulating boxes should not be lower than 50um. ” This clause is prone to ambiguity. :lol
