What are the errors in the total height or total length of the heat exchanger during the manufacturing process?

What are the errors in the total height or total length of the heat exchanger during the manufacturing process? For example, the total height of my device is 1000 mm, but in actual production it is 990 mm. May I ask the experts: is such a device considered qualified? Are there any standard regulations? I am extremely grateful.
It is specified in detail in GB151, page 93, 6.16.1.
In 151, the total length of the heat exchanger seems to be represented only by a letter, but there is no specific numerical value! I wonder if there are any more tips?
For the 2# sus321 heat exchanger, the total length seems to be indicated in 6.16.1 with only one character ‘L’ specified, without any actual numerical value.
This can be used to check the free tolerance, right? I often heard people talk about it in the workshop before, but I don’t know exactly how to do it
I know that there are regulations in the tema regarding the allowable dimensional tolerances for various components. That is, the error within this range is allowed.
