    Shelf life of two-part methacrylate

    MintJulep, you make an excellent point. This adhesive is unique to this application and has been put in MRB and can not be issued without a formal deviation. The deviation is time specific not to exceed 30 days. I share your concern about the "slippery slope". Thank you.

    Shelf life of two-part methacrylate

    Have an ISO audit starting today and wanted to get an internal deviation in place. I've expedited the next shipment of adhesive and will use the expired product under this deviation until the new shipment arrives. Thanks again for your able assistance.

    Shelf life of two-part methacrylate

    We use a two-part methacrylate in a manufacturing process. The adhesive has a 6 month shelf life and the activator 12 months after date of shipment from the manufacturer. Sometimes when we get it from the distributor, it has only two months shelf life left. We have some adhesive that expired in...

    Our customer has requested that we verify the .400 +/- .002 at FA on the CMM then hard gauge for production.

    Gauge callout on drawing

    Thanks all. So it seems the .400 and 2.900 values are somewhat arbitrary and the .400 is just what 2.900 yields when trigged out. Have I got it? See attached. http://files.engineering.com/getfile.aspx?folder=5888d124-91d1-4820-a5a1-1ad30a9a77af&file=Eng-tips_sketch.doc

    Gauge callout on drawing

    I have a drawing with GAUGE attached to two dimensions. Have not seen this callout before and am unsure what it means. The attached sketch is representative of the drawing. If you can shed some light, I'd appreciate it.
