Good stuff. Thank you moderator! Thumbs up! ! !

Good resource, worth downloading and learning* .

I was so dizzy after seeing it, the stuff is very good, it would be better to categorize it!

JJG130~2004 Calibration Regulations for Working Liquid-in-glass Thermometers seems to have been replaced by JJG130~2011 Calibration Regulations for Working Liquid-in-glass Thermometers. :)

Where can I download the things listed in this directory?

There are so many standards, haha. I’m doing the testing. I can come over and take a look in the future.
