Sweeper battery UN38.3 Certification: The "invisible guardian" of family safety

In the rapid popularization of smart home devices, sweeping robots have become the "cleaning small expert" of modern families, and the lithium batteries that provide power for them are building a security line through UN38.3 certification. This seemingly professional technical certification is closely related to the safety of each user's home.

First, the safety pillar behind smart cleaning

Sweeping robots free people's hands through autonomous navigation and intelligent algorithms, but lithium batteries, as their core power source, may face risks such as extreme temperatures and mechanical shocks during transportation and use. UN38.3 certification is the international standard for the safety of lithium battery transportation, covering eight categories of test items such as height simulation, thermal shock, overcharge, etc., to verify the stability of the battery in air transportation and daily use. According to statistics, in the global transportation accidents caused by lithium batteries in 2023, the proportion of products that have not passed UN38.3 certification is as high as 78%.

Second, the "customs clearance secret" of certification declaration

1, enterprises apply for UN38.3 certification need to prepare three core information:

2, technical documents: including cell/battery specifications, BMS protection circuit description

3, sample data: provide battery batch number, charge and discharge cycle test report

4, compliance certification: ISO9001 system certification, raw material MSDS documents

Through the four-step process of "pre-assessment - sample delivery testing - report review - Certificate issuance", certification can usually be completed within 25 working days. The vibration test and heat abuse experiment are the "ultimate test", which simulates the severe turbulence and high temperature environment that may be encountered in transportation.

Third, the triple value of certification enables products

1, safety upgrade: through 72 hours of high-altitude low-pressure simulation test, to ensure the stability of the battery under 10,000 meters of high-altitude cabin pressure of the cargo plane

2, market access: recognized by international organizations such as IATA and ICAO, cross-border e-commerce platform access rate increased by 40%

3, brand value added: the end product packaging can be affixed with UN marks, consumer purchase intention increased by 25%

In the wave of smart home boom, UN38.3 certification has jumped from basic compliance to a catalyst for industry innovation. Consumers gain peace of mind through the certified logo, and companies open up access to global markets. With the iteration of new technologies such as solid-state batteries, the certification system will continue to optimize the safety assessment dimension. The deep integration of technological innovation and safety standards is leading the smart home appliance industry to a safer and more sustainable future.
