The preface of HG/T 20519-2009 clearly states that \"the original provision in HG20519.9-1992 regarding ‘equipment installation drawings’ has been removed.\"
Reply to 2# jintchinssen: Thank you. The version I downloaded didn’t have a preface, so I didn’t see it; I was wondering about that. It wasn’t found in the explanatory notes either. So, isn’t there any reason given in the preface? Moved to another major?
The preface also does not outline specific reasons; it merely provides a general statement that, with the advancement of technology, some outdated provisions have been removed or modified. However, regarding the deletion of the “equipment installation drawings,” I personally think it should fall under the responsibility of the equipment specialty, that is, the equipment specialty should put forward requirements to the civil engineering or structural engineering specialties.
Are there any new standards for equipment installation diagrams?
