Adhesives Application -Temperature & Humidity Control 8.5.4 , 8.5.1p -

Hello Everyone,
I would like to address the records necessity for adhesives to fulfill the control of temp/ humidity requirements.
A big part of it goes to
-the mix up time (in the case of two parts mix adhesives)
-application start up time
- finish application time
All if them are tied up with temp/ humidity

Let's start with this:
The AS 9100 standard in it's 8.5.4 , 8.5.1p talks about securing the shelf life/ and .making sure the temp/hum. are under control while handling of the adhesives.

Respectively 8.5.1 p describes the requirements for storing in a controlled environment if such requirement for specific chemicals exist.

The objective evidence to fulfill this requirement would have been to demonstrate the monitoring of temperatures and humidity either by handy process or electronic system.

That is pretty straightforward to understand.

I have been wondering about other adjacent reqs. Namely many adhesives have a application time (meaning adhesives still remains a consistency and properties covered by spec) , tack time (a time after which that adhesive will not adhere to the surface)


These in turn if not controlled within a standard temp and humidity of e.g B2 seleant- temp 77 F and 50% of relative humidity , could lead to reducing the application time greatly.

Humidity greater the standard values could lead to reduce a application time, or cause to dispose the material hence the material structure can be contaminated by humidity.

Question:

Dependent on varying temperatures/ humidities right in the center of the shop floor area what is the best practical way to capture these changing factors either by mechanics or by the system to meet the AS 9100 standard for controlling application time.



Would they be just automatic sensors with display that would have told mechanics "you have a max application time by XXX Hour from now". I this case we would not have had an actual start / finish application time.


Would it be hand process dictating mechanics to write down the temp/ hum. values at each stage

: mixing time

: start of application time

: finish of application time


Or you encountered a way different method to fulfill this AS9100 req in practice.



Would you please advice?

Thank you

Andy

 

Happy New Year to All!
Thanks Andy,
The intention was to bring up 8.5.1p)
"the control and monitoring of utilities and supplies (e.g., water, compressed air, electricity, chemical products)
to the extent they affect the conformity to product requirements ..."
In my mind this one (e.g for sealant used to produce conforming products) does not just affect the special processes only. It also touches other processes that could impact quality of products (for example: primers, glues, and other chemical items)

This kind of control could be dual (storage area) as well as application phisical area.
Both need to have infrastructure and controls in place to achieve that goal, otherwise I think it is just guessing under which enviromental conditions both activities were carried out.
Now, if there are handling implications conditions (where temp/ humudity) could have a significant during application phase the question goes.

Is this still outside of AS9100 8.5.1p requirement as per your view, and these type of chemical items as above beyond the special process do not fall under the standard?
