        Bluetooth audio quality inspection report processing——ZRLK

        Author:中認聯(lián)科 time:2021-12-31 Ctr:1513

        Bluetooth audio is a speaker product that transmits sound through Bluetooth. It has a built-in Bluetooth chip and connects to Bluetooth playback devices such as mobile phones, tablets, and notebooks, replacing traditional wire-connected wireless devices with Bluetooth connections. However, in general, if such products want to be put on the domestic e-commerce platform, 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.

        Why do you want to make a quality inspection report?

        Common reporting purposes are:

        ◆ Enter online shopping malls such as JD.com and Tmall;

        ◆ Bidding/bidding;

        ◆ Report for project acceptance;

        ◆ Supplier requirements;

        ◆ Publicity report;

        ◆ Settled in 4S shop (general car supplies);

        ◆ Reports required for TV shopping;

        ◆ Reports required by stores (such as Wal-Mart, Carrefour, Rainbow, Guoanju, B&Q, etc.).

        Note: If electronic and electrical products enter JD.com and Tmall, you need to confirm whether the product needs 3C certification. If it is not in the 3C range, the test report is useful. If it is in the 3C range, you need to provide 3C certification first.
