Since February 2019, the Japanese have a pencil series of three standards are revised, February 20, 2019 issued a JIS S 6005:2019 "シ ャ ー プ ペ ン シ ル with core" (see figure 1).On March 23, 2020 issued a JIS S 6006:2020 "pencil, color pencil and び そ れ ら に with い る core" (see figure 2).On March 23, 2020 issued a JIS S 6013:2020 "シ ャ ー プ ペ ン シ ル" (see figure 3), makes Japanese pencil series standard more perfect.
In three new revision of the standard, JIS S 6006-2020 of the pencil, color pencil and び そ れ ら に with い る core "of the change is more, while our country's" pencil "standard GB/T 26704-2011 for nearly ten years time no revisions, the differences between the two, should cause us more attention and enough attention.
