Foreword
This standard replaces GB/T 3518-1995 "flake graphite."
Compared with GB/T 3518-1995, this standard the following modifications.
--- Increased product marking;
--- Table 3 (carbon graphite technical requirements) in "LC150-99" changed to "LG150-99";
--- Increase in Tables 3 and 4 for comments. Determination of graphite, fixed carbon content of non-volatile requirements may Except volatile;
--- 7.4.2 deletes the original standard time on product quality objection handling;
--- Table 4 fixed carbon content ≥85% moisture "≤1.00%" modify "≤0.50%", Table 5 in the water
"≤2.00%" modify "≤1.00%";
--- Table 5 carbon graphite technology requirements, "the sieve ≤25.0%" modify "≤20.0";
--- In Chapter 8 logo increased product marking.
