    Author:中認(rèn)聯(lián)科 time:2021-11-27 Ctr:1147

    Bluetooth speakers refer to audio equipment with built-in Bluetooth chips that replace traditional wire connections with Bluetooth connections. By connecting with Bluetooth playback devices such as mobile phones, tablets, notebooks, etc., it is convenient and quick. But generally, if such products want to be sold on domestic e-commerce platforms, a quality inspection report is required.

    What is a quality inspection report?

    The so-called quality inspection report refers to the safety and performance testing of the product, successfully entering other platforms such as Tmall, JD.com or supermarkets, or as a reference standard for consumers. According to the three-level standard (national standard, ministerial standard and enterprise's own standard), carry out quality assessment, make basic evaluation, and analyze the reasons for qualified or unqualified quality. This is the main part of the quality inspection report. It is necessary to have a laboratory authorized by China Metrology Certification (CMA) + China National Accreditation Service for Conformity Assessment (CNAS), and the quality inspection report issued by it is valid.
