I know they are supposed to be in acordance with J-STD-001D, but what does that entail? All I can find on the internet is that J-STD-001D allows a maximum of 1.56 micrograms/cm2 NaCl equivalent when tested in accordance with IPC-TM-650, Test Method 2.3.25 or 2.3.26. </div> <div class="e_p"> Also, I am curious as to whether DI water removes non dissolved solids and not dissolved solids. Is that true? </div> </div>
