A small mistake in the new regulations
Thread Content
Article 8.4.1(2) "The accuracy of the pressure gauge shall not be lower than level 1.6", which should be level 1.5.
This post was last edited by baictq on 2009-11-4 19:04. The measurement accuracy levels of general pressure gauges are 1.0, 1.6, 2.5, and 4.0. That’s right~ The 1.5 level seems to have been replaced by 1.6~
If you look at the new "Capacity Regulations" ("Safety Technical Supervision Regulations for Stationary Pressure Vessels"), you will know the origin. The pressure gauge has been changed to 1.6 level, so...!
The measurement accuracy levels of precision pressure gauges are 0.1, 0.16, 0.25, and 0.4 respectively.； The measurement accuracy levels of general pressure gauges are 1.0, 1.6, 2.5, and 4.0 respectively. Level 1.5 is the old standard and has long been replaced.
Rong Gui is right. If you find a problem and raise it, it doesn’t matter even if you are wrong. Let’s learn together * , improve together.

study* , raise questions and solve them, so that everyone can learn * Profound.
What criteria are used to determine level 1.6? Thanks
It's okay to make mistakes. People summarize theories and improve themselves through mistakes.
It seems that I thought I was promoted, haha
