Please advise whether you mean official spark test from laboratory(Spectrometer test).
From our Q.A.’ s NC Report was done in-house by hand grinding machine and also mentioned its result in that report. If you need official chemical analysis report, we will send to lab. Please note that there will be an expense that we need to charge to LJC. Please advise if you accept, we will send a sample to test.
Should you have any, please feel free to contact me.
