With the rise of multimedia equipment, the International Electrotechnical Commission introduced the new standard IEC / CISPR 32,35. This new standard combines the previous information broadcast acceptance functions, PC mainframe, and television standards in various fields. Therefore, RRA has also updated the test standards and test methods accordingly. From January 1, 2016, KN 32 and KN 35 officially replaced KN 13, KN20, KN 22 and KN 24, KN32 reference standard CISPR 32 d1.0 (2012.01.), KN35 reference standard CISPR 35 I / 412 / CDV (2012.01.).
