    Basic standards and certification items for CQC certification of lithium batteries

    Author:中認(rèn)聯(lián)科 time:2020-07-08 Ctr:1155

    CQC mark certification is one of the voluntary product certification services carried out by the China Quality Certification Center. The CQC mark is applied to indicate that the products meet the relevant quality, safety, performance, electromagnetic compatibility and other certification requirements. The scope of certification involves mechanical equipment and electrical equipment. , Electrical appliances, electronic products, textiles, building materials and more than 500 products. The GB31241 standard for lithium batteries began to be enforced on August 1, 2015, replacing the previous 3306 standard. The certification rule implemented is CQC certification. (It can also be said that the test standard for CQC certification is GB31241) So how do you apply for CQC certification for lithium batteries?

    CQC certification GB31241 applicable product range:

    This standard applies to the following portable electronic products lithium-ion batteries and battery pack examples are as follows:

    (a) Portable office products: notebook computers, PDAs, etc.;

    (b) Mobile communication products: mobile phones, cordless phones, Bluetooth headsets, intercoms, etc.;

    (c) Portable audio and video products: portable TV sets, portable DVD players, MP3/MP4 players, cameras, video cameras, voice recorders, etc.;

    (d) Other portable products: electronic navigators, digital photo frames, game consoles, e-books, etc.
