NIST has a temperature reference for dimensional calibration


http://ts.nist.gov/WeightsAndMeasures/Publications/gentechlength.cfm


Also, the National Conference for Standardizing Laboratories has a

publication, RP-7, for site selection and design of a metrology

laboratory.


Plagiarizing from "Guidelines for Laboratory Design", J. Wiley & Sons

(1987), p.41, "The temperature in most laboratory buildings does not

require close regulation, that is, no better than +/- 3 F."  This book

also refers to a draft ANSI-ASHRAE ventilation standard 86-62 (1986)

which recommended air exchange rates for public, commercial and

industrial areas. Local building codes were mentioned as sources. 


The CRC Handbook of Laboratory Safety, 5th edition has a large chapter

titled Laboratory Facilities - Design and Equipment.


I think there may be OSHA suggestions for temperatures of general office

areas.

Subject: [DCHAS-L] laboratory/office environmental control questions


I have been challenged by my engineering group to consider the following


questions as they pertain to a mixed use office/laboratory building. Any


input would be useful.


What is the target (set point) temperature, by space type.

What is the acceptable range of temperature, by space type.

What is the response time requirements of the temperature controlling 

system

What is the target (set point) humidity, by space type.

What is the acceptable range of humidity, by space type.

What is the response time requirements of the humidity controlling

system

What is the minimum number of room air changes per hour, by space type.

What is the maximum number of room air changes per hour, by space type.

What are the pressure level requirements between / relative to each

space 

type.

What is the response time requirements of the pressure controlling

system.



Kind regards,
