Please I need your input on this. We purchased magnets to be used to fulfill one of our prerequisite programs. I am wondering what documents I need to get from the supplier of the magnet. I requested for calibration certificate and initial strength of the magnet. They can not provide these two but only certificate of conformity that says the magnet meet the standard and specification of MMPA-0100-00. The certificate provided does not mention the type of magnet either. They just told us verbally that it is a rare earth magnet. The magnets were purchased from Bunting. Imo, the certificate of conformity is not enough. But I don't know what to request for as they claimed no customer has ever requested for calibration certificate from them.
