Does anyone know what spec defines a Temperature range of 68°-72° for dimensional measurement? Every spec Ive looked at thus far defines the temp as 68° period. If you deviate from that temp you must compensate for thermal effects. The reason Im asking is because we are manufacturing a magnesium housing that has a 23.501" +/-.001 dia. If we check it in the shop (71°) it checks 23.501, check it in the lab (68°) it checks 23.499 which obviously is undersize..
Ok
2013_junkie I can probably email you the standard
DAN_M is correct with the 50% RH but the +/- thing is incorrect. It's 68° in that standard too. If it's anything other than that temperature then there are formulas you use to calculate from your results. If you want to get into it that deep I will gladly send you a copy. and I was wrong this actually relates to the 73 version. So the 72° thing not sure of where that came from.
Here is just an example. This $hit goes on and on.
