Current pump noise testing standards
Thread Content
Yesterday I posted a post about the measurement of GB10890-89 noise. The moderator deducted 30 points, explaining that this standard has been invalidated. However, after searching online for a long time, I could not find the current noise testing standards, including standards for pumps and pharmaceutical factories. Could you please share them with me?~~
I'm also looking for it, I'm looking for pump operating noise, bearing vibration, temperature, etc.* * Industry related standards.
GB Z 1-2002 Hygiene standards for industrial enterprise design
Wow! Thirty points were deducted. What a tragedy.
I searched all morning and found two standards: GB/T21271-2007 Vacuum Technology Vacuum Pump Noise Measurement JB/T8098-1999 Pump Noise Measurement and Evaluation Methods Among them, JB/T8098-1999 has been published in the standard sharing area, GB/T21271-2007. I can’t find a free one. I hope you guys can help.
Where did 85db come from? Many people are asking for this now. It's simply not possible. In addition, the motor itself is very high
:lol:lol:lol Metering pump noise should not be high
85db is a general standard requirement. Generally, small pumps can achieve it without any problem, but it is more difficult for large pumps.
