HG/T21543 is a big standard, and .5 and .12 in it are all minor items.
Big standards will emerge. 1.2.3.4 .....
This is the album, there are no extensions or sub-sections. This is the first time I used this standard. Maybe I didn’t look carefully and didn’t see the clues?
What comes with it is the construction drawing purchased separately, which saves our designers from having to draw it. It is a bit expensive. It is the same as the standard manhole drawing. You can draw the construction drawing yourself according to the simplified diagram in the text.
I looked at the relevant content based on the drawings, and it seems to be the page numbers in this standard. But the expression of item 5 is very straightforward (page P34). The other two are like this. I don’t know if my guess is correct? !
