ASME B89.6.2 - Temperature and Humidity Environment for Dimensional Measurements

B

BOBSKY

Our objective in the near future is to be compliant to the latest requirements, I have heard 50% humidity is spec. for ambient temp of 65 to 75 degrees does anyone know where this is written? our lab is 21 c and usually around 23% humidity, how many dollars required to bump to 50% if required? and contacts in Ontario Canada.

THANKS BOBSKY.

I have found some ISO specs for test and calibration that state required temperature but not humidity. I think it depends on the type of M&T's being performed. What are you calibrating?

Hi,
If you would acquire ASME B89.6.2 entitled " Temperature and Humidity Environment for Dimensional Measurement", I think this will answer your questions.

Hi
I am Yew, we also facing the same problem.
Our auditor asking us how our company setup the temperature and humidity for inhouse calibration laboratory.
Our temperature setting are 23 +/- 2°C
Humidity setting : 55 +/-10% RH.
Do any one have any reference regarding laboratory temp and humidity specification to be share.
I also found under NCSL laoboratory design them only mention about temperature control for laboratory. 23°c for electrical laboratory.

Regards,
Yew Seng Chuan.

Noted and thank for advice.
Do any one have reference such as below.
1.ASME B89.6.2 or
2.NCSL Recommended Practice RP-7: Laboratory Design
I need them be my reference to determine my inhouse calibration laboratory temperature and humidity setting.
I try to seach through internet the reference above, but unable to get.

Thank.

Regards,

Welcome to the forum.

The ASME standard should be copyrighted and hence you can't find any in the web but I am not too sure about RP-7.

We do have 2 other threads where you should be able to gather bits and pieces of info:

Calibration Environment - Micrometers - NCSL RP 7 - Laboratory Design

Environmental Conditions for Calibration - Temperature and Humidity‎

An a2la link is provided in one of the post. Use it to see if you can access RP-7, otherwise they are available from sellers like SAI.
