technology (see 6.7, A.10 of this Edition);
--- Moved all specific operating conditions to Annex A (see Annex A of this Edition; Clause
7 of the 2018 Edition);
--- Add general test conditions and new specific test conditions (e.g., robotic equipment)
(see A.8.11 of this Edition);
--- Change the statistical evaluation-based conformity requirements in the main text and
give in the form of an Annex (see Annex D of this Edition; Clause 8 of the 2018 Edition).
This Document equivalently adopted CISPR 14-1.2020 Electromagnetic Compatibility –

Electromagnetic Compatibility Requirements for Household Appliances, Power Tools
and Similar Appliances - Part 1.Emission;
--- Adjust the order of abbreviations in 3.10;
--- Add "Note. P = only the rated power of the motor” in Table 8, which is consistent with
Tables 6 and 7;
--- Correct “see Figures 12 to 19” in Table 9 into “see Figures 15 to 22”;
--- Add the description “The lower limit is applied at transition frequency” in footnote a of
Table 11, which is consistent with Tables 2, 5, 6 and 9;
--- Correct “(see Figure 12 for construction details)” in 5.1.6 into “(see Figure 10 for
construction details)”;
--- Correct “(see 10)” in 5.2.1.2.2 into “(see Figure 10)”;
--- Correct “(see 3)” in 5.2.2.1 to “(see Figure 3)”;
--- Correct “(see Clause 9)” in 5.4.2.3 into “(see Clause 7)”;

to keep it consistent with the text;
--- Correct "Use Figure 6" in the last block diagram of Figure 9 into "Use Figure 8";
--- Change the c in Figure 16 from the origin plus a line segment into an arrow plus a line
segment to make it clear that c refers to the cable in the figure;
--- Correct "0.3 0.4" in Figures 23, 24, and 25 to "0.3~0.4" to make it clear that the length
of the outer cable bundle is a range value;
--- Change “click rate. N=n2 ×f/T (see 5.4.2.2)” in Table B.1 into “click rate. Ns=ns × f/Ts (see
5.4.2.3)” to keep it consistent with the text;
--- Correct "5.4.3.4" in the last paragraph of Annex C.3 into "5.4.3.5";
--- Correct the arrow pointing position of x1 in Figure D.1.
